Port Speed

SUMMARY Learn about port speed on a device or line card, support for multiple port speed details, guidelines and how to configure the port speed.

Port Speed Overview

Port speed refers to the maximum amount of data that the line card transmits through a port at any given second. Port speed is measured as follows:

  • Kilobits per second (Kbps)

  • Gigabits per second (Gbps)

  • Terabits per second (Tbps)

Table 1 describes the different types of port speed configuration.

Table 1: Types of Port Speed Configuration

Port Speed Configuration Type

Description

PIC or MIC Level

You can configure all the ports in one PIC or MIC to operate at the same speed. For example, you can configure all the ports of a PIC that support port speed of 100 Gbps to operate at 100 Gbps speed. If you do not specify the speed by using the pic-mode statement, then the port operates in the default speed.

Port Level

You can configure each port to operate at a different speed and thus enable each port. When you configure the port speed at the port level, you have the flexibility of operating the ports of the line card at different supported speeds.

When you change the speed of a specific port in a given PIC using the speed statement, then only the speed of that port is modified. All other ports in the PIC remain unaffected. For example, you can configure four 10-Gigabit Ethernet interfaces on port 0, one 40-Gigabit Ethernet interface on port 1, and one 100-Gigabit Ethernet interface on port 2.

Table 2: Port Speed Configuration at PIC Level– Chassis Hierarchy

Configuration Steps

PIC Level

Step 1: At the PIC level, specify the operating speed for the PIC.

[edit chassis fpc fpc-slot pic pic-number]
user@host# set pic-mode pic-speed

For example:

[edit chassis fpc 0 pic 0]
user@host# set pic-mode 100g

Step 2: (Optional) At the PIC level, configure the number of active physical ports that operate at the speed configured in Step 1.

[edit chassis fpc fpc-slot pic pic-number]
user@host# set number-of-ports number-of-active-physical-ports

For example:

[edit chassis fpc 0 pic 0]
user@host# set number-of-ports 4

Step 3: (Optional) Specify the number of logical interfaces that you want to create on a physical port.

[edit chassis fpc fpc-slot pic pic-number]
user@host# set number-of-sub-ports number-of-sub-ports

For example:

[edit chassis fpc 0 pic 1]
user@host# set number-of-sub-ports 4

Step 4: (Optional) Specify the port number that you want to power off.

[edit chassis fpc fpc-slot pic pic-number]
user@host# set port port-number unused

For example:

[edit chassis fpc 0 pic 1]
user@host# set port 2 Unused 

Step 5: Verify the configuration.

[edit chassis fpc 0 pic 0]
user@host# show 
pic-mode 100G;
number-of-ports 4;
[edit chassis fpc 0 pic 1]
user@host# show 
number-of-sub-ports 4;

Step 6: Commit the configuration.

Table 3: Port Speed Configuration at Port Level– Chassis Hierarchy

Configuration Steps

Port Level

Step 1: At the port level, specify the operating speed for the port.

[edit chassis fpc fpc-slot pic pic-number]
user@host# set port port-number speed (10g | 40g | 100g)

For example:

[edit chassis fpc 0 pic 0]
user@host# set port 0 speed 40g
user@host# set port 1 speed 100g

Step 2: (Optional) Specify the number of logical interfaces that you want to create on a physical port.

[edit chassis fpc fpc-slot pic pic-number]
user@host# set number-of-sub-ports number-of-sub-ports

For example:

[edit chassis fpc 0 pic 1]
user@host# set number-of-sub-ports 4

Step 3: (Optional) Specify the port number that you want to power off.

[edit chassis fpc fpc-slot pic pic-number]
user@host# set port port-number unused

For example:

[edit chassis fpc 0 pic 1]
user@host# set port 2 Unused 

Step 4: Verify the configuration.

[edit chassis fpc 0 pic 0]
user@host# show 
port 0 {
    speed 40g;
}
port 1 {
    speed 100g;
}
[edit chassis fpc 0 pic 1]
user@host# show 
port 1 {  
number-of-sub-ports 4;
}

Step 6: Commit the configuration.

Table 4 describes the steps to configure the port speed for non-channelized interfaces from the [edit interfaces] hierarchy.

Table 4: Port Speed Configuration for non-channelized interfaces -Interfaces Hierarchy

Configuration Steps

Non-Channelized Interfaces

Step 1: To indicate the speed at which the ports operate, configure the speed statement for the desired interfaces.

[edit interfaces interface-name]
user@host# set speed (10g | 25g | 40g | 50g| 100g | 400g)

For example:

[edit interfaces et-1/0/3]
user@host# set speed 100g

Step 2: To configure the speed for a group of ports.

[edit ]
user@host# wildcard range set interfaces interface-name speed speed

For example:

[edit ]
user@host# wildcard range set interfaces et-1/0/[0-5] speed 100g 

Step 3: To specify the number of interfaces you want to configure per port.

Not applicable

Step 4: (Optional) To control the number of interfaces created on a physical port, use the unused statement. If you configure a port as unused, no interfaces are created for that port irrespective of the port profile configuration for that port.

[edit]
user@host# set interfaces interface-name unused 

For example:

[edit]
user@host# set interfaces et-2/0/3 unused

In this example, no interfaces (channelized or non-channelized) are created on port 3 of the line card installed in the FPC slot 2.

Step 5: Verify the configuration.

et-x/y/z { 
speed 100g;
 
 unit 0 { 
    ...
 } 
  ... 

 unit N {
    ... 
 }

}
...
et-x/y/z { 
unused;
 
}

Step 6: Commit the configuration.

Table 5: Port Speed Configuration for channelized interfaces -Interfaces Hierarchy

Configuration Steps

Channelized Interfaces

Step 1: To indicate the speed at which the ports operate, configure the speed statement for the desired interfaces.

[edit interfaces interface-name]
            user@host# set speed (10g | 25g | 40g | 50g| 100g | 400g)
        

For example:

[edit interfaces et-1/0/3]
            user@host# set speed 100g
        

Step 2: To configure the speed for a group of ports.

[edit ]
            user@host# wildcard range set interfaces interface-name speed speed
        

For example:

[edit ]
            user@host# wildcard range set interfaces et-1/0/[7-12] speed 100g 
        

Step 3: To specify the number of interfaces you want to configure per port.

[edit interfaces interface-name]
                user@host# set number-of-sub-ports number-of-sub-ports
            

For example:

[edit interfaces et-1/0/3]
                user@host# set number-of-sub-ports 4
            

In this example, in Step 1 and Step 2, you configure 4x100GE channelized interfaces.

Step 4: (Optional) To control the number of interfaces created on a physical port, use the unused statement. If you configure a port as unused, no interfaces are created for that port irrespective of the port profile configuration for that port.

[edit]
                        user@host# set interfaces interface-name unused 
                    

For example:

[edit]
                        user@host# set interfaces et-2/0/4 unused
                    

In this example, no interfaces (channelized or non-channelized) are created on port 4 of the line card installed in the FPC slot 2.

Step 5: Verify the configuration.

et-x/y/z { 
                            speed 100g;
                            number-of-sub-ports 4;
                            
                            et-x/y/z:0 { 
                            unit 0{

                            } 
                            }
                            
                            et-x/y/z:1 { 
                            unit 0{ 
                            ...
                            } 
                            }
                            
                            et-x/y/z:2 { 
                            unit 0{ 
                            ...
                            } 
                            }
                            
                            et-x/y/z:3 { 
                            unit 0{ 
                            ...
                            } 
                            }
                            
                            ...
                        
et-x/y/z:6 { 
                            unused;
                            
                        }

Step 6: Commit the configuration.

Interface Naming Conventions

Each interface name includes a unique identifier and follows a naming convention. When you configure the interface, use the interface name. You can either configure a port as a single interface (non channelized interface) or partition the port into smaller data channels or multiple interfaces (channelized interfaces).

When multiple interfaces are supported on a physical port, you use the colon (:) notation in the interface naming conventions as a delimiter to differentiate the multiple interfaces on a physical port. In the interface naming convention, xe-x/y/z:channel:

  • x refers to the FPC slot number.

  • y refers to the PIC slot number.

  • z refers to the physical port number.

  • channel refers to the number of channelized interfaces.

When the 40-Gigabit Ethernet interfaces (et-fpc/pic/port) are channelized as 10-Gigabit Ethernet interfaces, the interface appears in the xe-fpc/pic/port:channel format, and channel is a value of 0 through 3.

Table 6 describes the naming formats for the channelized and non-channelized interfaces.

What is Oversubscription?

Oversubscription occurs when you configure the speed of a port at the PIC level, and all ports that support that speed are enabled. To prevent oversubscription, you can configure the number of active ports that operate at the configured speed. Interfaces are created only for active ports. When oversubscription of Packet Forwarding Capacity is not supported, the demand on each Packet Forwarding Engine should be less than or equal to its forwarding capacity.

For information on the line card, see MX Series 5G Universal Routing Platform Interface Module Reference.

To view the hardware compatibility matrix for optical interfaces, transceivers, and DACs supported on MPC7E-MRATE, see Hardware Compatibility Tool (HCT).

Table 7 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

Follow these guidelines when you configure the speed of a port:

  • By default, all ports of the MPC7E-MRATE MPC operate as four 10-Gigabit Ethernet interfaces. Therefore, when booting the MPC:

    • If you have not configured the port speed or if you have configured an invalid port speed, an alarm is generated to indicate that the configuration is invalid. All the ports operate as four 10-Gigabit Ethernet interfaces.

    • If valid port speeds are configured, the PIC and MIC operate at the configured speed.

  • When you change an existing port speed configuration at the port level, you must reset the MPC7E-MRATE PIC for the configuration to take effect. An alarm is generated indicating the change in port speed configuration.

  • When you change an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid. For example, on the MPC7E-MRATE, if you configure the port speed of port 3 as 100 Gbps, it is an invalid configuration. MPC7E -MRATE supports 100 Gbps only on ports 2 and 5. The MPC continues to operate using the existing port speed configuration or the default port speed.

  • You cannot configure the port speed at the PIC level and the port level simultaneously. Error messages are displayed when you attempt to commit such configurations.

  • When you configure the port speed at the port level, only the configured ports are enabled. Other ports are disabled.

For information on how to configure the speed at the PIC level, see Table 2. For information on how to configure the speed at the port level, see Table 3.

Starting with Junos OS Release 20.4R1, you can configure 1-Gbps speed on 10-Gigabit Ethernet ports of the MPC7E-10G.

Each of the forty 10-Gigabit Ethernet ports can be configured to operate as 1-Gigabit Ethernet port. To configure the operating speed of the 10-Gbps port to 1-Gbps, use the speed statement at the [edit interfaces interfacename gigether-options] hierarchy level. After you commit the configuration, the operating speed of the 10-Gbps port changes to 1-Gbps speed without any MPC, PIC, or interface bounce. To view the speed configured on the interface, use the show interfaces extensive command. In the output, the Speed Configuration field displays the current operating speed of the interface. If the interface is configured with 1-Gbps speed, then the Speed Configuration field displays 1G; if the interface is configured with 10-Gbps speed, Speed Configuration displays AUTO.

Follow these guidelines when you configure the speed of the port:

  • By default, all ports of the MPC7E-10G MPC operate as four 10-Gigabit Ethernet interfaces. Therefore, when booting the MPC:

    • If you have not configured the port speed or if you have configured an invalid port speed, an alarm is generated to indicate that the configuration is invalid. All the ports operate as four 10-Gigabit Ethernet interfaces.

    • If valid port speeds are configured, the PIC and MIC operate at the configured speed.

  • When you change an existing port speed configuration at the port level for MPC7E-10G, you must restart the MIC for the configuration to take effect.

    An alarm is generated indicating the change in port speed configuration.

  • When you change an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid.

  • You cannot configure the port speed at the PIC level and the port level simultaneously. Error messages are displayed when you attempt to commit such configurations.

  • When you configure the port speed at the port level, only the configured ports are enabled. Other ports are disabled.

For information on how to configure the speed at the PIC level, see Table 2. For information on how to configure the speed at the port level, see Table 3.

Port Speed on MX10003 MPC Overview

For information on the line card, see MX Series 5G Universal Routing Platform Interface Module Reference.

For information about platform support, see Hardware Compatibility Tool (HCT).

Table 18 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

Table 18: Port Speed for MX10003 MPC

PIC

Port Number

Port Speed Supported

PIC 0 (Fixed-port PIC)

0-5

40-Gigabit Ethernet

All the 4x10-Gigabit Ethernet ports can operate in 1 Gbps mode.

PIC 1 (Multi-Rate MIC)

0-11

40-Gigabit Ethernet

4x10-Gigabit Ethernet

100-Gigabit Ethernet

On the non-MASCEC MIC, all the 4x10-Gigabit Ethernet ports can operate in 1 Gbps mode.

Follow these guidelines when you configure the speed of a port:

  • By default, the MX10003 router comes up with the PIC mode where all the interface operates at the same speed of 10-Gbps. That is, by default, both the PICs (PIC 0 and PIC 1) operate at 10-Gbps speed. To use different port speeds, you must first switch to the port mode and then change the default speed.

    To change the default speed, you must select a port and configure a different port speed on it and reset both the PICs for the configuration to take effect. For example, select 40GE or 100GE on PIC 1 and 10GE on PIC 0. For this configuration to take effect, you must reset both PICs.

  • Regardless of the line card— MIC (PIC1) or fixed-port PIC (PIC0) installed —you must configure both the PICs and all the associated ports, under the [edit chassis] hierarchy. Configuring ports on only one of the PICs results in an invalid configuration.

  • The port speed configuration on the fixed-port PIC and the MIC must be homogenous. However, at port level you can configure port speeds in heterogeneous mode.

    For example, if you want to configure the port speed as 10 Gbps, the port speed of the fixed-port PIC and the MIC should be configured to 10 Gbps. If you want to configure the port speed as 40 Gbps, the port speed of the fixed-port PIC and the MIC should be configured to 40 Gbps. However, if you choose to configure all ports of the MX10003 MPC to operate as 100-Gigabit Ethernet interfaces, the ports on the MIC have to be configured to 100 Gbps and the number-of-ports number-of-active-physical-ports statement on the fixed-port PIC must be set to 0.

  • When you configure the port speed at the port level, only the configured ports are active. Other ports are disabled.

  • When you choose an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid.

  • You cannot configure the ports which will oversubscribe the Packet Forwarding Engine. For example, a combination of eleven 100-Gigabit Ethernet interfaces on the MIC and ten 10-Gigabit Ethernet interfaces on the fixed-port PIC will result in an invalid configuration. If you try to commit an invalid configuration, the configuration will get committed. However, the port will not be activated. You can execute the show chassis alarms to display the error message. The valid configuration in this case would be eleven 100-Gigabit Ethernet interfaces on the MIC and eight 10-Gigabit Ethernet interfaces on the fixed-port PIC.

  • You cannot configure the speed of the port at the PIC level and the port level simultaneously. Error messages are displayed when you try to commit such configurations.

  • When you change an existing port speed configuration at the port level, you must reset the PIC for the configuration to take effect. When you change an existing port speed configuration at the PIC level, the MPC automatically resets the PIC.

For information on how to configure the speed at the PIC level, see Table 2. For information on how to configure the speed at the port level, see Table 3.

Follow these guidelines when you configure the speed of the port:

  • By default, the MX204 router comes up with PIC mode where all the interfaces operate at the same speed of 10-Gbps. By default, both the PICs (PIC0 and PIC1) operate at 10-Gbps speed. To use different port speeds, you must first switch to the port mode. When you switch modes, either from PIC mode to port mode or from port mode to PIC mode, the PIC restarts automatically.

  • To change the default speed, you must select a port and configure a different port speed on it and reset both the PICs for the configuration to take effect. For example, select 40GE or 100GE on PIC0 and 10GE on PIC1. For this configuration to take effect, you must reset both PICs.

  • You cannot configure 1-Gbps speed at PIC level and port level. But, you can configure the port configured at 10-Gbps speed to operate at 1-Gbps speed by using the speed statement. After you commit the configuration, the operating speed of the 10-Gbps port changes to 1-Gbps speed, but the show interface command displays the speed configuration (operating port speed) as 1GE.

  • Regardless of the line card— MIC (PIC1) or fixed-port PIC (PIC0) installed —you must configure both the PICs and all the associated ports, under the [edit chassis] hierarchy. Configuring ports on only one of the PICs results in an invalid configuration.

  • In PIC mode, the MX204 router does not support heterogeneous mode. That is, in PIC mode if 40-Gbps or 100-Gbps speed is configured on PIC 0, then the number-of-ports on PIC 1 must be configured to 0 only. The heterogeneous mode is supported only on port mode.

  • When you configure the port speed at the port level, only the configured ports are active. Other ports are disabled.

  • When you choose an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid.

  • You cannot configure port speed at the PIC level and the port level simultaneously. Error messages are displayed when you try to commit such configurations.

For information on how to configure the speed at the PIC level, see Table 2. For information on how to configure the speed at the port level, see Table 3.

Port Speed on MIC-MACSEC-20GE Overview

For information on the MIC, see MX Series 5G Universal Routing Platform Interface Module Reference.

To view the hardware compatibility matrix for optical interfaces, transceivers, and DACs supported on MIC-MACSEC-20GE, see Hardware Compatibility Tool (HCT).

Table 31 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

10-Gigabit Ethernet

Default: 10-Gigabit Ethernet

Follow these guidelines when you configure the speed of the port:

  • By default, all ports of the MIC-MACSEC-20GE MIC operate as 1-Gigabit Ethernet interfaces. In this mode, the ports in the MIC are created as “ge” interfaces distributed across PIC0 and PIC1.

  • The twenty 1-Gigabit Ethernet SFP ports distributes the ports across PIC0 and PIC1, that are logical PICs on the physical MIC. The two 10-Gigabit Ethernet are created by distributing the ports in either of the PICs.

  • The MIC-MACSEC-20GE MIC also provides 128-bit and 256-bit MACsec encryption on all the twenty 1-Gigabit Ethernet and on the two 10-Gigabit Ethernet ports. By default, 128-bit MACsec encryption is supported.

  • In 10-Gigabit Ethernet mode, the ports in the MIC will be created as “xe” interfaces one each on PIC 0 and PIC 1. In this mode, the 10G ports physically maps to the front panel port 8 and 9 on the second PIC of the MIC (that is marked on the front panel of the MIC). In the 10G mode, only the marked ports are operational and other physical ports are disabled.

  • Use the pic-mode 10G command to set the PIC to operate in 10G mode. Both the PICs on the MIC must be configured in the same pic-mode, otherwise the configuration does not take effect. Any mis-configuration results in the PICs operating in default pic-mode, that is, to be in 20x1GE where all ports are in 1-GE port speed.

  • When you change the speed of the port from 1-Gbps to 10-Gbps or vice versa, the Flexible PIC Concentrator (FPC) in MX240, MX480, MX960 routers and the Forwarding Engine Board (FEB) in MX80, MX104 routers undergoes an automatic bounce or a reboot.

  • The 10-Gbps-capable ports (ports 8 and 9) of the MIC-MACSEC-20GE MIC may display the link status as up while the peer side is down. In this case, it is recommended to disable auto-negotiation and set the speed to 1-Gbps on the peer side to bring the link up on the peer side.

For information on how to configure the speed at the PIC level, see Table 2. For information on how to configure the speed at the port level, see Table 3.

Follow these guidelines when you configure the speed of a port:

  • By default, the MPC10E-10C-MRATE comes up with the PIC mode where all the interface operates at the same speed of 100-Gbps. That is, by default, all the PICs (PIC 0 and PIC 1) operate at 100-Gbps speed.

  • When you change the speed at the PIC level, the PIC restarts automatically with the new configured speed.

  • When you configure the speed of a port at the port level, then only the speed of that port is modified. All other ports in the PIC remain unaffected.

  • You cannot configure the port speed at the PIC level and the port level simultaneously. Commit fails when you configure the port speed at the PIC level and port level simultaneously.

  • Oversubscription of Packet Forwarding Engine (PFE) capacity is not supported. The demand on each PFE must be less than or equal to its forwarding capacity.
  • You can configure active ports to prevent oversubscription. See Table 37 for list of supported active ports on MPC10E-10C-MRATE.

For information on how to configure the speed at the PIC level, see Table 2. For information on how to configure the speed at the port level, see Table 3.

Port Speed Support on MPC10E-10C-MRATE

Different PICs in the MPC10E-10C-MRATE can operate at different speeds. That is, PIC speed of one PIC does not apply to the other PICs in the MPC.

Follow these guidelines when you configure the speed of a port:

  • If you do not configure the port speed at the PIC level using the pic-mode option, then the default port speed is 100 Gbps.

  • Ports 0 through 4 on each PIC of the MX2K-MPC11E MPC supports speeds of 100 Gbps.

  • When you change the speed at the PIC level, the PIC restarts automatically with the new configured speed.

  • You cannot configure the port speed at the PIC level and the port level simultaneously. Error messages are displayed when you attempt to commit the configuration.

  • When you change the port configuration at the port level, the interfaces corresponding to the affected port are deleted and then re-created.

  • You can configure a maximum bandwidth of 500 Gbps per PIC. For example, if you configure the speed of Port 0 of a PIC to 400 Gbps, and the speed of Port 1 of a PIC to 100 Gbps, then you cannot configure any additional ports on that PIC. If you attempt to configure an additional port, it is an invalid configuration.

  • If you configure the port speed of a port on any PIC to 100 Gbps and then configure the port speed of port 0 of the same PIC to 400 Gbps, an alarm is generated to indicate that you must restart the PIC. The 400-Gigabit Ethernet interface is created only after you manually restart the PIC.

  • When you change an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid. The MPC continues to operate using the existing port speed configuration or the default port speed.

For information on how to configure the speed at the PIC level, see Table 2. For information on how to configure the speed at the port level, see Table 3.

Software Feature Support

Description

Forward Error Correction (FEC)

  • By default, 200-Gigabit Ethernet interfaces and 400-Gigabit Ethernet interfaces support KP4 FEC mode. You cannot disable FEC mode explicitly.

  • FEC mode is based on the type of optics connected. With non juniper optics, you can enable FEC mode by manually configuring it. When you manually configure the FEC mode, all the interfaces on a port must be configured with same FEC mode. For example, for a 4x100-Gigabit Ethernet configuration mode, each of the four 100-Gigabit Ethernet interfaces must be configured with either all FEC74 or all FEC91-KR4 mode.

For information about FEC support, see fec (gigether).

Maximum Transmission Unit (MTU) Size

Maximum MTU of size 16000 bytes for transit traffic. Ingress interface limits is 9000 bytes.

Port Speed Configuration

  • For Junos OS Evolved Releases 19.4R1S1 and 20.1R1, you can configure the port speed at the [edit chassis ] hierarchy.

  • For Junos OS Evolved Releases 20.1R2, 20.2R1, and later, you can configure the port speed at the [edit interfaces] hierarchy.

Default: All the active ports operate in 400-Gigabit Ethernet mode.

Starting in Junos OS Evolved Release 20.1R2 and 20.2R1, we now support a new port profile configuration to configure port speeds on the PTX10K-LC1201 line card. You can now configure the port speed on the PTX10K-LC1201 line card by using the port profile configuration commands in the [edit interfaces] hierarchy. To streamline the configuration, the new port profile configuration commands are migrated from the [edit chassis] hierarchy to the [edit interfaces] hierarchy for the PTX10K-LC1201 line card.

Starting in Junos OS Evolved Release 20.4R1, you can configure 10Gbps speed and select the wavelength with SFP+ optics by plugging in the QSA adapter on the QSFP/QSFP+ ports of PTX10K-LC1201 line card. You can now configure the 10Gbps speed by using the set interfaces et-<fpc>/<pic>/<port> speed <10g> or set interfaces et-<fpc>/<pic>/<port> speed <10g> number-of-sub-ports (1) commands. You can select the wavelength of the SFP+ ports by using the set interfaces et-<fpc>/<pic>/<port>:channel number optics-options wavelength wavelength command and view the output using the show interfaces diagnostics optics name command.

Follow these guidelines when you configure the speed of a port:

  • On non-channelized interfaces, the prefix et- is used irrespective of the speed configured. If you do not configure the speed, by using the optional speed command, default speed is assigned to the interface.

  • On channelized interfaces, the prefix et- is used irrespective of the speed configured. All channelized interfaces have the same speed. You cannot configure an individual speed for each channelized interface. You can configure the number of channelized interfaces by using the number-of-sub-ports command.

  • You can configure the active physical ports in a PIC. By default, all the physical ports in an interface are active. To control the number of interfaces created on a physical port in a PIC, use the unused command. If you configure a port as unused, no interfaces (channelized or non-channelized) are created for that port.

  • When you change the speed of the port, or change the number-of-sub-ports per port, or configure or remove the number-of-sub-ports, the interfaces will be deleted and re-created for that port.

  • If you have not configured the port profile for a specific port and the port is active, interfaces are created for the port with default speed based on the platform or FPC. You can control the number of interfaces created by using the unused command.

  • Interfaces are created irrespective of the physical presence of optics. If the plugged in optics does not match the interface speed, the interfaces are marked down.

  • You can configure port profiles in the command line interface without the physical presence of an FPC. If an invalid port profile configuration is detected while booting a FPC, an alarm is generated. Also, the default port profile is selected for that PIC. Also, if the port profile configuration is changed while the FPC is up and running, and the new configuration is invalid, an alarm is generated. The existing port profile configured continues to be used for that PIC.

For information about how to configure the speed of a port for a non-channelized interface using the new interfaces hierarchy, see Table 4. For information about how to configure the speed of a port for a channelized interface using the new interfaces hierarchy, see Table 5.

Description

Port speed configuration

Supports interfaces [edit interfaces interface-name] hierarchy.

MTU size

ACX7100-48L router WAN interfaces support maximum MTU size of 9216 bytes for transit traffic.

Forward Error Correction (FEC) support

By default, FEC119 (KP4) is enabled on 400-Gigabit Ethernet and 200-Gigabit Ethernet interfaces.

The FEC mode is based on the type of optics connected. When you configure the FEC mode, you must configure all interfaces on the port with the same FEC mode. For example, if you channelize a 40-Gigabit Ethernet port to operate as four 10-Gigabit Ethernet interfaces, you must configure each of the four 10-Gigabit Ethernet interfaces with either all FEC74 or all FEC91-KR4.

For information about FEC support, see fec (gigether).

To configure the speed of non-channelized interfaces, see Table 4. To configure the speed of channelized interfaces, see Table 5.

Follow these guidelines when you configure the speed of a port:

  • Use the speed command to set the speed on tri-rate SFP port. Use the show chassis pic fpc-slot 0 pic-slot 0 command to view supported port speeds.
  • Port Macro does not support the combination of port speed, 25Gbps and 50Gbps. For example, for ports 0-7, you can specify the speed for port 4 as 50G and for port 2 as 10G. Alternatively, you can specify the speed of port 4 as 25G and for port 2 as 10G. When you configure the speed for port 4 as 50G and for port 2 as 25G and commit the configuration, an alarm is generated.

  • An alarm is raised when optics does not support configured speed.

Description

PIC Level or Port Level Configuration

Only port level speed configuration is supported.

Port speed configuration:

  • Supports only [edit interfaces interface-name] hierarchy from Junos OS Evolved Release 20.3R1 onwards.

  • Supports [edit chassis] hierarchy in Junos OS Evolved 20.2 releases.

MTU size

PTX10001-36MR router WAN interfaces support maximum MTU of size 16000 bytes for transit traffic. However for the traffic that is destined to host or is originating from host (such as protocol traffic), the maximum MTU limit is 9500 bytes. If any of the host bound packets or host originating packet is above 9500 bytes, then the packet will be dropped. Hence, if you are expecting host packets greater than 9500 bytes, then the WAN interface MTU value must be set as value less than or equal to 9500 bytes.

Forward Error Correction (FEC) support

  • By default, KP4 FEC is enabled on 400 and 200-Gigabit Ethernet interfaces.

    Since it is mandatory to enable KP4 FEC option for 200 and 400-Gigabit Ethernet interfaces, you cannot disable KP4 FEC explicitly.

  • The FEC mode is based on the type of optics connected, but it in some cases (with non juniper optics) can be enabled through manual configuration as well. In such case, all the interfaces on a port must be configured with same FEC mode. For example, for a 4x100-Gigabit Ethernet configuration mode, each of the four 100-Gigabit Ethernet interfaces must be configured with either all FEC74 or all FEC91-KR4 mode.

For information about FEC support, see fec (gigether).

Table 62: Channelization and FEC support on 400- and 200-Gigabit Ethernet capable ports

Speed Supported

You can channelize to:

400-Gigabit Ethernet capable ports

  • One or two 200-Gigabit Ethernet interfaces (1x200G or 2x200G)

  • Four 100-Gigabit Ethernet interfaces or two 100-Gigabit Ethernet interfaces (4x100G or 2x100G)

  • Two 50-Gigabit Ethernet interfaces or eight 50-Gigabit Ethernet interfaces (2x50G or 8x50G)

  • Four 25-Gigabit Ethernet interfaces or eight 25-Gigabit Ethernet interfaces (4x25G or 8x25G)

  • One 40-Gigabit Ethernet interface (1x40G)

  • Four 10-Gigabit Ethernet interfaces (4x10G)

100-Gigabit Ethernet capable ports

You can configure all four 100-Gigabit Ethernet capable ports (ports 4, 5, 6, and 7) to operate at 100-Gbps speeds.

Note that, you can configure port 4 and port 6 to operate at 1x100-Gbps, 4x10-Gbps, 4x25-Gbps, or 1x40-Gbps speeds with the following conditions:

  • When port 4 is configured in 4x10-Gbps, 4x25-Gbps, or 1x40-Gbps, then port 5 must be configured as 'unused'.

  • When port 6 is configured in 4x10-Gbps, 4x25-Gbps, or 1x40-Gbps, then port 7 must be configured as 'unused'.

Starting in Junos OS Evolved Release 20.3R1, you can configure the port speed on the PTX10001-36MR router by using the port profile configuration commands in the [edit interfaces] hierarchy. To streamline the configuration, the port profile configuration commands are migrated from the [edit chassis] hierarchy to the [edit interfaces] hierarchy for the PTX10001-36MR router.

From Junos OS Evolved Release 21.2R1, we support autonegotiation and linktraining using 400G DAC cable for PTX10001-36MR. This is not a default behavior. Use auto-negotiation under [edit interfaces interface-name ether-options] hierarchy level to enable autonegotiation and link training. Enabling autonegotiation automatically enables link training. This advertises configured speed on the interface hierarchy. It does not upgrade or downgrade speed based on peers advertised capability.

Autonegotiation and link training is supported only on the following channelization:

  • One 400-Gigabit Ethernet interfaces (1x400G)
  • Two 200-Gigabit Ethernet interfaces (2x200G)
  • Four 100-Gigabit Ethernet interfaces (4x100G)

Configure speed at Port Level

To configure the PTX10001-36MR router at port level, follow the configuration steps in Table 3 in 20.2 releases. See speed for more details.

From Junos OS Evolved Release 20.3R1 you must use, set interfaces et-<fpc>/<pic>/<port> speed <10g | 25g | 50g | 40g | 100g | 200g | 400g>, or set interfaces et-<fpc>/<pic>/<port> speed <10g | 25g | 50g | 40g | 100g | 200g | 400g> number-of-sub-ports (1|2|4|8) commands to configure the speed on the ports.

You can configure port profiles in the command line interface without the physical presence of an FPC. If an invalid port profile configuration is detected while booting a FPC, an alarm is generated. Also, the default port profile is selected for that PIC.

If the port profile configuration is changed while the FPC is up and running, and the new configuration is invalid, an alarm is generated. The existing port profile configured continues to be used for that PIC.

You can configure any supported speed on 400-Gbps capable ports. Configuring speed on one of the 400-Gbps capable port will not disrupt the traffic on any other ports.

But, for 100-Gbps capable ports only speeds of 100-Gbps, 25-Gbps, 40-Gbps, and 10-Gbps are valid.

You must explicitly configure the ports that must be powered off, using the following command:

set chassis fpc fpc-slot pic pic-slot port port-num unused.

From Junos OS Evolved Release 20.3R1 you must use, the following command:

set interfaces et-<fpc>/<pic>/<port> unused

If you configure Unused command for a physical port in a PIC, then no channelized and non-channelized interfaces will be created. See Unused for more information.

The Table 65 specifies which ports must be marked unused. If this rule is violated, then an alarm indicating port speed configuration error is raised. In such case, the existing running configuration will continue to be applied on such ports.

If the router reboots with such an invalid configuration, then the port with 40-Gbps, 4x10-Gbps, or 4x25-Gbps speed configuration and its counterpart port will not have any interfaces created for them.

Table 63 provides you the ports that you must power-off while configuring different speeds.

0/2/5 and 0/2/7

Note:

You can configure a port with more than one type of channelization mode for a given speed. For example, you can channelize a port to 1x100-Gbps, 2x100-Gbps, or 4x100-Gbps to configure the port to operate in 100-Gbps speed.

To specify which of these channelization modes the port should operate in, execute the following command:

set chassis fpc fpc-slot pic pic-slot port port-num number-of-sub-ports (1|2|4|8)

From Junos OS Evolved Release 20.3R1 to specify which of these channelization modes on the ports, you must execute the following command at the [edit interfaces] hierarchy:

set interfaces et-<fpc>/<pic>/<port> speed <10g | 25g | 50g | 40g | 100g | 200g | 400g> number-of-sub-ports (1|2|4|8)

See number-of-sub-ports for information on how to operate at different channelized speed.

When the number-of-sub-ports are not specified, the number of channels are created as per Table 64:

Table 64: Number of sub-ports supported for a particular speed

Port speed

Valid values for number-of-sub-ports

200-Gbps

1, 2, 4

40-Gbps

1

50-Gbps

2, 8

25-Gbps

4, 8

10-Gbps

4

Follow these guidelines when you configure the speed of a port:

  • The default number of channels is considered as 1 for all speeds if number of sub-ports is not configured explicitly.

  • If the number-of-sub-ports, do not match the type of optic connected and the configuration is invalid, then even though the interfaces are created, the links would remain down. A syslog entry will be added indicating usage of the wrong optic type. For example, if a port is channelized for eight channels and the optics inserted is for four channels, then the links will be down.

  • If the number-of-subports configuration is incorrect, then the error will be logged in syslog and an alarm is raised.

  • The router has a fabric capacity of 9.6 Tbps. When the router operates in 24 400-Gigabit Ethernet mode, the fabric does not experience an oversubscription. The oversubscription occurs when the router is configured in 24 400-Gigabit Ethernet and 12 100-Gigabit Ethernet mode.

  • To avoid oversubscription of a PIC, the sum of total speed configured on ports 4 to 11 within the PIC must be less than 1.6 Tbps.

Use the show chassis pic fpc-slot 0 pic-slot 0 command in 20.2 release at the [edit chassis] hierarchy to know the speed that each port is configured for in the PIC. From Junos OS Evolved Release 20.3R1 you must use the operational command show interfaces port-profile.

Port Speed on PTX10K-LC1202-36MR Overview

For information on the line card, see PTX10008 Line Card Components and Descriptions.

For information about platform support, see Hardware Compatibility Tool (HCT).

PTX10K-LC1202-36MR is a new fixed-configuration line card with 36 built-in ports which you can install in PTX10008 routers. On the PTX10K-LC1202-36MR, you can choose to configure the line card:

  • To operate at 3.6T mode, configure all the 36 ports to 100-Gbps speed, or

  • To operate at 4.8T mode, configure the four 400 GE ports (4, 10, 24, and 30) to operate at 400-Gbps speed and the remaining ports to operate at 100-Gbps speed.

Table 66 summarizes the supported port speeds on PTX10K-LC1202-36MR for PTX10008 Routers.

Table 4 and Table 5 describe the steps to configure the port speed for channelized and non-channelized interfaces from the [edit interfaces] hierarchy.

To configure ports at different speed, use the set interfaces et-<fpc>/<pic>/<port> speed <10g | 25g | 40g | 100g | 400g> number-of-sub-ports <1|2|4|8> command.

For the steps to configure the port speed from the [edit interfaces] hierarchy. See speed for more details.

To channelize an interface, use the number-of-sub-ports command. The number-of-sub-ports specifies the number of channelized interfaces that you can configure on a physical port with the specified speed. Each channel operates at the specified speed. The default value of number-of-sub-ports per optics is 1. See number-of-sub-ports.

When the number-of-sub-ports are not specified, the number of channels are created as per Table 67:

Table 67: Number of sub-ports supported for a particular speed

100-Gbps

You can configure channelization on port 0 to port 3 and port 18 to port 21 with the following guidelines:

  • The 1x10-Gigabit Ethernet, 4x10-Gigabit Ethernet or 1x40-Gigabit Ethernet and 4x25-Gigabit Ethernet channelization is supported only on even numbered ports (that is, 0, 2, 18, 20).

  • When the even port x is channelized, you must set the odd port x+1 as unused. You must explicitly configure the ports that must be set as unused, using the following command:

    set interface et-<fpc>/<pic>/<port> unused

    See Table 5 and Unused for more details.

  • You cannot configure 1x10-Gigabit Ethernet, 4x10-Gigabit Ethernet or 1x40-Gigabit Ethernet and 4x25-Gigabit Ethernet simultaneously on the following ports:

    • port 0 and 2

    • port 18 and 20

You can configure port profiles in the command line interface without the physical presence of an FPC. If an invalid port profile configuration is detected while booting a FPC, an alarm is generated. Also, the default port profile is selected for that PIC.

If the port profile configuration is changed while the FPC is up and running, and the new configuration is invalid, an alarm is generated. The existing port profile configured continues to be used for that PIC.

To configure FEC mode, see fec (gigether).

You can configure every interface to loopback mode, see loopback.

Table 68 lists the naming conventions used for interfaces on PTX10K-LC1202-36MR (for 100-Gbps, 2x100-Gbps, 400-Gpbs, and 4x100-Gbps speeds) for PTX10008 routers. PTX10008 routers support eight PTX10K-LC1202-36MR line cards.

Introduction to Port Speed

Use this topic to understand more about port speed in a network device or in a network component such as a line card.

Port Speed for Routing Devices

The total port speed of the MIC/MPC cannot exceed the forwarding capacity of the Packet Forwarding Engine.

Port Speed on MPC7E-MRATE

MPC7E (MPC7E-MRATE) is a fixed-configuration MPC and is supported on MX240, MX480, MX960, MX2010, and MX2020 routers. MPC7E-MRATE contains two built-in PICs, PIC 0 and PIC 1. Each PIC has six physical ports that support quad small form-factor pluggable plus (QSFP+) transceivers. The default port speed is 10 Gbps for all ports. Each of the six ports of PIC 0 and PIC 1 supports speeds of 10 Gbps and 40 Gbps. However, only ports 2 and 5 on both the PICs support 100 Gbps speed.

MPC7E-MRATE has an aggregate forwarding capacity of 480 Gbps and a forwarding capacity of 240 Gbps on each Packet Forwarding Engine. Oversubscription of Packet Forwarding Engine capacity is not supported. The demand on each Packet Forwarding Engine must be less than or equal to its forwarding capacity. For instance, for MPC7E-MRATE, the demand on each Packet Forwarding Engine must be less than or equal to 240 Gbps.

For information about the naming conventions for interfaces on MPC7E-MRATE MPC, see Interface Naming Conventions for MPC7E-MRATE.

Starting with Junos OS Release 20.4R1, you can now configure 1-Gbps speed on 10-Gigabit Ethernet ports of the MPC7E-10G.

Each of the forty 10-Gigabit Ethernet ports can be configured to operate as 1-Gigabit Ethernet port. To configure the operating speed of the 10-Gbps port to 1-Gbps, use the speed statement at the edit interfaces interfacename gigether-options hierarchy level. After you commit the configuration, the operating speed of the 10-Gbps port changes to 1-Gbps speed without any MPC, PIC, or interface bounce. To view the speed configured on the interface, use the show interfaces extensive command. In the output, the Speed Configuration field displays the current operating speed of the interface. If the interface is configured with 1-Gbps speed, then the Speed Configuration field displays 1G; if the interface is configured with 10-Gbps speed, Speed Configuration displays AUTO. For more information, see speed. Use the show interfaces extensive command to view the speed of the interface.

Port Speed on MIC-MRATE

MPC8E (MX2K-MPC8E) and MPC9E (MX2K-MPC9E) support two separate slots for MICs as field replaceable units (FRUs). Each of the MIC slots supports only one MIC– MIC-MRATE. MIC-MRATE consists of 12 physical ports that support QSFP+ transceivers and multiple port speeds of 100  Gbps, 40  Gbps, and 10  Gbps. You can configure a port to operate in a specific speed based on your requirement. The default port speed is 10  Gbps for all ports. MIC-MRATE also supports breakout transceivers, which you can use to split a 40-Gigabit Ethernet port into four 10-Gigabit Ethernet ports. MIC-MRATE ports can be split into a maximum of 48 10-Gigabit Ethernet interfaces.

MPC8E has an aggregate forwarding capacity of 960  Gbps and a forwarding capacity of 240  Gbps on each Packet Forwarding Engine. MPC9E has an aggregate forwarding capacity of 1600  Gbps and a forwarding capacity of 400  Gbps on each Packet Forwarding Engine. Oversubscription of Packet Forwarding Engine capacity is not supported. The demand on each Packet Forwarding Engine must be less than or equal to its forwarding capacity. For instance, for MPC8E, the demand on each Packet Forwarding Engine must be less than or equal to 240  Gbps and for MPC9E, the demand per Packet Forwarding Engine must be less than or equal to 400  Gbps.

On MPC8E with MIC-MRATE, you can configure four 100-Gigabit Ethernet interfaces and two 40-Gigabit Ethernet interfaces per MIC. All other interfaces are automatically disabled. On MPC9E with MIC-MRATE, you can configure eight ports as 100-Gigabit Ethernet interfaces and the other ports can be configured only as 40-Gigabit Ethernet Interfaces or 10-Gigabit Ethernet interfaces.

For information about the naming conventions for interfaces on MPC8E and MPC9E, see Interface Naming Conventions for MIC-MRATE.

Port Speed on JNP10K-LC2101

JNP10K-LC2101 is a fixed-configuration MPC and is supported on MX10008 routers. JNP10K-LC2101 contains six built-in PICs, PIC 0 to PIC 5. Each PIC has four physical ports that support quad small form-factor pluggable plus (QSFP+) transceivers. The default port speed is 10 Gbps for all ports. Each of the four ports of PIC 0 to PIC 5 supports speeds of 10 Gbps (using breakout cables), 40  Gbps, and 100  Gbps.

MX10008 routers support eight JNP10K-LC2101 MPCs. By default, each JNP10K-LC2101 MPC provides a maximum bandwidth of 1.44  Tbps. JNP10K-LC2101 has six Packet Forwarding Engines, each providing a maximum bandwidth of up to 240  Gbps, which cannot be oversubscribed. You can configure JNP10K-LC2101 to provide an increased bandwidth of 2.4  Tbps. The demand on each Packet Forwarding Engine must be less than or equal to its forwarding capacity. For instance, by default, for JNP10K-LC2101, the demand on each Packet Forwarding Engine must be less than or equal to 240  Gbps. However, if you have configured JNP10K-LC2101 to provide an increased bandwidth of 2.4  Tbps, the demand on each Packet Forwarding Engine must be less than or equal to 400  Gbps.

For information about the naming conventions for interfaces on JNP10K-LC2101 MPC, see Interface Naming Conventions for JNP10K-LC2101.

Starting with Junos OS Release 19.4R1, you can now configure 1-Gbps speed on 10-Gigabit Ethernet ports of the JNP10K-LC2101 MPC.

Each of the 40-Gigabit Ethernet port can be split to four 10-Gigabit Ethernet ports that can be configured to operate as 1-Gigabit Ethernet port. You must use 4x10GE LR breakout optics (QSFPP-4X10GE-LR) at the MX10008 or MX10016 end and 1-Gigabit Ethernet EX optics at the remote end. It is only optional to use Juniper optics (SFP-GE40KM) at the remote end, as any vendor's EX (not SX or LX) optics can be used. Refer to the Hardware Compatibility Tool for the list of pluggable transceivers supported on the MX10008 router.

Note:

Any interface operating at 10-Gbps speed can be independently converted to 1-Gbps speed. For example, in multi–rate connections through split cables, when one of the ports operates at 1-Gbps speed, the other three ports can be configured either with 1-Gbps speed or 10-Gbps speed.

To configure the operating speed of the 10-Gbps port to 1-Gbps, use the speed statement at the edit interfaces interfacename gigether-options hierarchy level. After you commit the configuration, the operating speed of the 10-Gbps port changes to 1-Gbps speed without any MPC, PIC, or interface bounce. To view the speed configured on the interface, use the show interfaces extensive command. In the output, the Speed Configuration field displays the current operating speed of the interface. If the interface is configured with 1-Gbps speed, then the Speed Configuration field displays 1G; if the interface is configured with 10-Gbps speed, Speed Configuration displays AUTO. For more information, see speed.

When you use the show interfaces extensive command to view the speed of the interface, the output does not display support for auto-negotiation. However, autonegotiation is supported when the interface speed is configured for 1-Gbps speed.

Note:

You cannot configure the 10-gigabit Ethernet interface, operating with a speed of 1-Gbps, as a member interface of a link aggregation group (LAG).

Port Speed on MIC-MACSEC-20GE

The MIC-MACSEC-20GE MIC provides 128-bit and 256-bit MACsec encryption on all the twenty 1GE and on the two 10GE ports in the following hardware configuration:

  • Installed directly on the MX80 and MX104 routers

  • Installed on MPC1, MPC2, MPC3, MPC2E, MPC3E, MPC2E-NG, and MPC3E-NG line cards on the MX240, MX480, and MX960 routers

By default, 128-bit MACsec encryption is supported.

The twenty 1-Gigabit Ethernet SFP ports distribute the ports across PIC0 and PIC1, that are logical PICs on the physical MIC. The two 10-Gigabit Ethernet SFP+ ports are physically located on PIC1. But, the 10-Gigabit interfaces are created by distributing the ports in either of the PICs. For information about the naming conventions for interfaces on MIC-MACSEC-20GE, see Interface Naming Conventions for MIC-MACSEC-20GE.

Note:
  • When the pic-mode is changed from 1-Gbps to 10-Gbps or vice versa, the Flexible PIC Concentrator (FPC) in MX240, MX480, MX960 routers and the Forwarding Engine Board (FEB) in MX80, MX104 routers undergoes an automatic bounce or reboot.

  • When the MIC-MACSEC-20GE is operating in the 10-Gbps mode, all the other 1-Gbps ports are disabled.

Guidelines for Configuring Port Speed on Routing Devices

This topic describes the guidelines to consider when configuring rate selectability at the port level or the PIC or MIC level.

Guidelines for Configuring Port Speed for MIC-MRATE MIC and MPC7E-MRATE MPC

This topic describes the guidelines to consider when configuring rate selectability at the port level or the PIC level for MIC-MRATE MIC and MPC7E-MRATE MPC:

  • If rate selectability is not configured, all ports of the MIC-MRATE MIC and MPC7E-MRATE MPC operate as four 10-Gigabit Ethernet interfaces by default. Therefore, when booting the MPC:

    • If rate selectability is not configured or if invalid port speeds are configured, an alarm is generated to indicate that the configuration is invalid. All the ports operate as four 10-Gigabit Ethernet interfaces.

    • If valid port speeds are configured, the PIC and MIC operate at the configured speed.

  • When you change an existing port speed configuration at the port level, you must reset the MPC7E-MRATE PIC for the configuration to take effect.

    Similarly, when you change an existing port speed configuration at the port level for MPC8E or MPC9E, you must reset the MIC for the configuration to take effect. You can use the request chassis mic mic-slot mic-slot-number fpc-slot fpc-slot-number (offline | online) command to reset the MIC and apply your configuration changes.

    An alarm is generated indicating the change in port speed configuration.

  • When you change an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid. For example, on the MPC7E-MRATE, if you configure the port speed of port 3 as 100 Gbps, it is an invalid configuration. MPC7E -MRATE supports 100 Gbps only on ports 2 and 5. The MPC continues to operate using the existing port speed configuration or the default port speed.

  • You cannot configure rate selectability at the PIC level and the port level simultaneously. Error messages are displayed when you try to commit such configurations.

  • When you configure rate selectability at the port level, only the configured ports are enabled. Other ports are disabled.

Guidelines for Configuring Port Speed for JNP10K-LC2101

This topic describes the guidelines to consider when configuring rate selectability at the port level or the PIC level for JNP10K-LC2101:

  • Each port on the JNP10K-LC2101 MPC supports speeds of 10 Gbps (using breakout cables), 40 Gbps, and 100 Gbps. However, JNP10K-LC2101 MPC does not support bandwidth oversubscription. So, when you configure the ports on all PICs, ensure that the demand on each Packet Forwarding Engine is less than or equal to its forwarding capacity. The default port speed for all PICs is 10G.

  • When you change an existing port speed configuration at the port level, you must reset the PIC for the configuration to take effect. When you change an existing port speed configuration at the PIC level, the JNP10K-LC2101 automatically resets the PIC.

  • When you change the number of active ports using the number-of-ports command, you must reset the PIC for the configuration to take effect. Interfaces are created only for active ports. Only the ports you configure are known as the active ports. The number of active ports enables you to handle bandwidth oversubscription.

    Note:

    You cannot configure the number of active ports at the port level. If you attempt to configure the number of active ports at the port level, an error message is displayed.

  • You cannot configure rate selectability at the PIC level and the port level simultaneously. Error messages are displayed when you try to commit such configurations.

  • When you change an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid. The MPC continues to operate using the existing port speed configuration or the default port speed.

Guidelines for Configuring Port Speed for MPC11E

This topic describes the guidelines to consider when configuring rate selectability at the port level or the PIC level for MPC11E:

  • If you do not configure rate selectability at the PIC level using the pic-mode option, then the default port speed is 100 Gbps.

  • Ports 1 through 4 on each PIC of the MPC11E MPC supports speeds of 100 Gbps.

  • On MPC11E, you cannot configure the number of active ports or the number of channelized-interfaces to be created on a port. The number-of-ports and number-of-sub-ports statements are not supported.

  • You cannot configure rate selectability at the PIC level and the port level simultaneously. Error messages are displayed when you attempt to commit the configuration.

  • When you configure rate selectability at the port level, only the configured ports are created in that PIC. Other ports are not created. When you change the port configuration at the port level, the interfaces corresponding to the affected port are deleted and then re-created.

  • When you change an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid. The MPC continues to operate using the existing port speed configuration or the default port speed.

MX10003 MPC Port Speed Overview

MX10003 MPC supports a Multi-Rate 12xQSFP28 Ethernet Modular Interface Card (MIC) and a fixed-port PIC (6xQSFPP). The MX10003 Packet Forwarding Engine has 6x40GE QSFPP ports on the fixed-port PIC and 12x100GE QSFP28 ports on the MIC. For more information see MX10003 MPC (Multi-Rate). Rate selectability enables you to configure the port speed either at the port level or at the MIC level. To configure all ports to operate at the same speed, you configure rate selectability at the MIC or PIC level. For more information see Configuring Port Speed on MX10003 MPC to Enable Different Port Speeds.To configure different port speeds for each port, you configure rate selectability at the port level, in which case only the ports that are configured are enabled. For more information see Configuring Port Speed on MX10003 MPC to Enable Different Port Speeds.

The ports on the MX10003 MPC are called rate-selectable or multirate ports as they support multiple port speeds. You can choose to configure all supported ports of the fixed port PIC or the MIC to operate at the same speed or configure all the ports at different supported speeds. However, all the PIC or MIC ports do not support all the port speeds. For example, you can choose to configure:

  • A port in 4x10GE mode using QSFPP-4x10GE optics and 4x10GE breakout cables.

  • A port in 40GE mode using QSFPP optics.

  • A port in 100GE mode using QSFP28 optics.

  • A port in 1GE mode (for the ports that is already operating in 10GE mode only) using QSFPP-4x10GE optics on fixed PIC and non-MacSEC MIC.

Note:
  • You can use the port-checker tool to check whether the combination of ports you want to use is valid or not.

  • You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on MX10003 router.

The MX10003 MPC supports three Packet Forwarding Engines. The forwarding capacity of each Packet Forwarding Engine is 400Gbps which cannot be oversubscribed.

The MIC supports 12 ports. Each Packet Forwarding Engine is mapped to 4 ports of the MIC. Port 0 through port 3 are mapped to PFE0, port 4 through port 7 are mapped to PFE1, and port 8 through port 11 are mapped to PFE2. The fixed-port PIC supports 6 ports. Each Packet Forwarding Engine is mapped to two ports of the fixed-port PIC. Port 0 and port 1 are mapped to PFE0, port 2 and port 3 are mapped to PFE1, and port 4 and port 5 are mapped to PFE2. You can use the command show chassis pic fpc-slot slot-number pic-slot slot-number to display Packet Forwarding Engine mapping information and port speed information.

Table 70 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

Note:

On non-MACsec MIC, you can configure one or all the 4X10-Gigabit Ethernet port to 1-Gigabit Ethernet mode.

Starting with Junos OS Release 18.1R1, the non-MACsec MIC on the MX10003 routers support 1-Gigabit Ethernet mode also on 10-Gigabit Ethernet mode ports.

Each of the 100-Gigabit Ethernet or 40-Gigabit Ethernet port can be split to four 10-Gigabit Ethernet ports that can be configured to operate as 1-Gigabit Ethernet port. You can also use 4x10GE LR breakout optics (QSFPP-4X10GE-LR) at the MX10003 end and 1-Gigabit Ethernet EX optics at the remote end. It is only optional to use Juniper optics (SFP-GE40KM) at the remote end, as any vendor's EX (not SX or LX) optics can be used. Refer to Hardware Compatibility Tool for the list of pluggable transceivers supported on MX10003 router.

On MX10003 routers, when the port operates in 10-Gbps speed, you can change the operating speed to 1Gpbs using the configuration speed 1G as follows:

set interfaces interface-name gigether-options speed 1g

Refer speed (Gigabit Ethernet interface) for more details.

Once you commit this configuration, the operating speed of the 10-Gbps port changes to 1-Gbps speed, but the show interface command displays for the field Physical interface (that is, the interface name prefix) as XE /_/ and the Speed Configuration (that is, operating port speed) as 1GE. On fixed-port PIC and non-MACsec MIC, you can configure one or all 10-Gbps port operating in 4X10-Gbps speed to operate in 1-Gbps speed.

1-Gbps speed is only supported in non-autonegotation mode.

Note:
  • Any interface operating at 10-Gigabit Ethernet mode can be independently converted to 1-Gigabit Ethernet mode. For example, in multi–rate connections through split cables, when one of the ports operates at 1GE mode, the other three ports can still be configured in 1GE or 10GE mode.

  • The MACsec MIC does not support 1-Gbps speed.

  • The rate selectability at PIC level and port level does not support 1-Gbps speed. But you can configure the port configured at 10-Gbps speed to operate at 1-Gbps speed using the speed (Gigabit Ethernet interface) configuration statement at Gigabit Ethernet interface level.

  • The 1-Gbps operation mode is only supported in non-autonegotiation mode.

  • ISSU is not supported for the interfaces that are configured with 1-Gigabit Ethernet mode. If ISSU upgrade is carried out in 1-Gigabit Ethernet mode, then the behavior is unexpected and traffic loss can be expected. Refer request vmhost software in-service-upgrade for more details.

To view the speed configured for the interface, execute the show interfaces extensive command. The Speed Configuration output parameter in the command output indicates the current operation speed of the interface. If the interface is configured with 1-Gbps speed, then Speed Configuration displays 1G; if the interface is configured with 10-Gbps speed, Speed Configuration displays AUTO.

For example:

In this example, the Speed Configuration output parameter displays 1G, which means the operation speed of xe-0/1/11:0 interface is 1-Gbps speed.

MX10003 MPC has an aggregate forwarding capacity of 1.2 Tbps and a forwarding capacity of 400 Gbps on each Packet Forwarding Engine. Oversubscription of Packet Forwarding Engine capacity is not supported. The demand on each Packet Forwarding Engine must be less than or equal to its forwarding capacity. For more information see, Supported Active Physical Ports for Configuring Port Speed to Prevent Oversubscription on MX10003 MPC. For instance, for MX10003 MPC, the demand on each Packet Forwarding Engine must be less than or equal to 400 Gbps.

For example, on the fixed-port PIC, if you configure the port speed on one ports as 40 Gbps or on two port as 40 Gbps, then you can configure the ports on the MIC in one of the following ways:

  • Three 100-Gigabit Ethernet interfaces

  • Two 100-Gigabit Ethernet and two 40-Gigabit Ethernet interfaces

  • Two 100-Gigabit Ethernet and eight 10-Gigabit Ethernet interfaces

The same rule is applicable to all Packet Forwarding Engines independently.

Note:

Only the Interface that is already operating at 10GE mode can be configured to operate at 1GE mode using speed (Gigabit Ethernet interface) configuration statement as follows:

set interfaces interface-name gigether-options speed 1g

Note the following caveats while configuring rate selectability on the MX10003 MPC:

  • By default, the MX10003 router comes up with the PIC mode where all the interface operates at the same speed of 10-Gbps. That is, by default, both the PICs (PIC 0 and PIC 1) operate at 10-Gbps speed. To use different port speeds, you must first switch to the port mode and then change the default speed.

    To change the default speed, you must select a port and configure a different port speed on it and reset both the PICs for the configuration to take effect. For example, select 40GE or 100GE on PIC 1 and 10GE on PIC 0. For this configuration to take effect, you must reset both PICs.

  • Regardless of the line card— MIC (PIC1) or fixed-port PIC (PIC0) installed —you must configure both the PICs and all the associated ports, under the [edit chassis] hierarchy. Configuring ports on only one of the PICs results in an invalid configuration.

  • The port speed configuration on the fixed-port PIC and the MIC must be homogenous. However, at port level you can configure port speeds in heterogeneous mode. For more information, see Configuring Rate Selectability on MX10003 MPC at Port Level.

    For example, if you want to configure the port speed as 10 Gbps, the port speed of the fixed-port PIC and the MIC should be configured to 10 Gbps. If you want to configure the port speed as 40 Gbps, the port speed of the fixed-port PIC and the MIC should be configured to 40 Gbps. However, if you choose to configure all ports of the MX10003 MPC to operate as 100-Gigabit Ethernet interfaces, the ports on the MIC have to be configured to 100 Gbps and the number-of-ports number-of-active-physical-ports statement on the fixed-port PIC must be set to 0.

  • When you configure rate selectability at the port level, only the configured ports are active. Other ports are disabled.

  • When you choose an existing port speed configuration with an invalid port speed configuration, an alarm is generated indicating that the port speed configuration is invalid.

  • You cannot configure the ports which will oversubscribe the Packet Forwarding Engine. For example, a combination of eleven 100-Gigabit Ethernet interfaces on the MIC and ten 10-Gigabit Ethernet interfaces on the fixed-port PIC will result in an invalid configuration. If you try to commit an invalid configuration, the configuration will get committed. However, the port will not be activated. You can execute the show chassis alarms to display the error message.

  • You cannot configure rate selectability at the PIC level and the port level simultaneously. Error messages are displayed when you try to commit such configurations.

  • When you change an existing port speed configuration at the port level, you must reset the PIC for the configuration to take effect. When you change an existing port speed configuration at the PIC level, the MPC automatically resets the PIC.

Invalid Port Configuration

You cannot configure the ports which will oversubscribe the Packet Forwarding Engine.

For example, a combination of eleven 100-Gigabit Ethernet interfaces on the MIC and ten 10-Gigabit Ethernet interfaces on the fixed-port PIC will result in an invalid configuration. If you try to commit an invalid configuration, the configuration will get committed. However, the port will not be activated. You can execute the show chassis alarms to display the error message. The valid configuration in this case would be eleven 100-Gigabit Ethernet interfaces on the MIC and eight 10-Gigabit Ethernet interfaces on the fixed-port PIC.

MX204 Router Port Speed Overview

The maximum amount of data that can be transmitted through a port at any given second either by a network device or by a component of the network device (such as a line card) is known as the port speed. Port speed is measured in kilobits per second (Kbps), gigabits per second (Gbps), and terabits per second (Tbps). If a port can be configured to support both single and multiple speeds, the port is known as a rate-selectable port. Because the port is part of a network device (router or switch) or a network component (such as MPC, MIC) the component is known as a rate-selectable component. Rate selectability enables you to configure different port speeds at the port level or at the PIC level.

The MX204 has four rate-selectable ports (referred to a PIC 0 ports) that can be configured as 100-Gigabit Ethernet ports or 40-Gigabit Ethernet port, or each port can be configured as four 10-Gigabit Ethernet ports (by using a breakout cable). The MX204 also has eight 10-Gigabit Ethernet ports (referred to as PIC 1 ports). On PIC 1, you can configure the 10-Gigabit Ethernet port(s) to operate in 1-Gigabit Ethernet mode (using speed (Gigabit Ethernet interface) command). The four rate-selectable ports supports QSFP28/QSFP+ transceivers, whereas the eight 10-Gigabit Ethernet ports supports SFP+ transceivers. Knowing the exact details of the port speeds for the PICs helps you to choose the speeds to configure on the ports or on the PICs. You can view the port speeds of the PIC by executing show chassis pic command. For more information, see MX204 Router Overview and Supported Active Physical Rate-Selectable Ports to Prevent Oversubscription on MX204 Router.

Note:
  • By default, the MX204 router comes up with the PIC mode where all the interface operates at the same speed of 10-Gbps. that is, by default, both the PICs (PIC 0 and PIC 1) operate at 10-Gbps speed. To use different port speeds, you must first switch to the port mode. When you switch modes, either from PIC mode to port mode or port mode to PIC mode, the PIC restarts automatically.

    To change the default speed, you must select a port and configure a different port speed on it and reset both the PICs for the configuration to take effect. For example, select 40GE or 100GE on PIC 0 and 10GE on PIC 1. For this configuration to take effect, you must reset both PICs.

  • Not all port combinations will work. So, it is recommended to use the port-checker tool to check whether the combination of ports you want to use is valid or not.

  • You can use the Hardware Compatibility Tool to find information about the pluggable transceivers supported on MX204 router.

The MX204 router supports two types of rate selectability configuration options:

  • PIC Level Configuration: To configure all ports to operate at the same speed, you configure rate selectability at the PIC level.

  • Port Level Configuration: To configure different port speeds for each port, you configure rate selectability at the port level, in which case only the ports that are configured are enabled.

To configure all ports to operate at the same speed, configure rate selectability at the PIC level, in which case you cannot configure the speed of individual ports. To configure rate selectability at the PIC level, use the pic-mode statement and specify the port speed. To configure different port speeds for each port, configure rate selectability at the port level, in which case only the ports that are configured are enabled. To configure rate selectability at the port level, use the speed statement to specify the speed of individual ports.

The examples below show the sample CLI command output of the port speed capability of the 4-port PIC 0 with QSFP+ transceivers and the 8-port PIC 1 with SFP+ transceivers on the MX204 router.

Note:

Supports 1–Gbps speed on 10 Gigabit Ethernet ports.

Starting with Junos OS Release 18.1R1, the 10-Gbps port can operate in 1-Gbps mode also.

Each of the four 100-Gigabit Ethernet or 40-Gigabit Ethernet port can be split to four 10-Gigabit Ethernet ports that can be configured to operate as 1-Gigabit Ethernet port. You can also use 4x10GE LR breakout optics (QSFPP-4X10GE-LR) at the MX204 end and 1-Gigabit Ethernet EX optics at the remote end. It is only optional to use Juniper optics (SFP-GE40KM) at the remote end, as any vendor's EX (not SX or LX) optics can be used. Refer to Hardware Compatibility Tool for the list of pluggable transceivers supported on MX204 router.

MX204 router also support 1-Gigabit Ethernet port on the fixed 10-Gigabit Ethernet SFPP ports with 1GE SFPs in it.

On MX204 routers, when the port is operating in 10-Gbps speed, you can change the operating speed to 1Gpbs using the configuration statement Speed 1G as follows:

set interfaces interface-name gigether-options speed 1g

Refer speed (Gigabit Ethernet interface) for more details.

Once you commit this configuration, the operating speed of the 10-Gbps port changes to 1-Gbps speed, but the show interface command displays for the field Physical interface (that is, the interface name prefix) as XE /_/ and the Speed Configuration (that is, operating port speed) as 1GE.

On MRATE PIC, each channel per port can be configured individually as 1-Gigabit Ethernet port.

Note:
  • The interface name prefix must be xe.

  • The rate selectability at PIC level and port level does not support 1-Gbps speed. But you can configure the port configured at 10-Gbps speed to operate at 1-Gbps speed using the speed (Gigabit Ethernet interface) configuration statement at Gigabit Ethernet interface level.

  • The 1-Gbps SFP port supports auto-negotiation. You can configure auto-negotiation by using the command set interfaces interface-name gigether-options auto-negotiation. For more information, see auto-negotiation.

To view the speed configured for the interface, execute the show interfaces extensive command. The Speed Configuration output parameter in the command output indicates the current operation speed of the interface. If the interface is configured with 1-Gbps speed, then Speed Configuration displays 1G; if the interface is configured with 10-Gbps speed, Speed Configuration displays AUTO.

For example:

In this example, the Speed Configuration output parameter displays 1G, which means the operation speed of xe-0/1/11:0 interface is 1-Gbps speed.

Note:

The MX204 router does not support heterogeneous mode. That is, in PIC mode if 40-Gbps or 100-Gbps speed is configured on PIC 0, then the number-of-ports on PIC 1 must be configured to 0 only.

On PIC 0, if ports 0, 1, and 2 are set to 100-Gbps, and port 3 is set to 10-Gbps or 40-Gbps, then you should configure all the 8 ports at PIC 1 to 0 (using number-of-port statement), and so on as listed in the below table.

The following table only lists few valid combination of port speeds on PIC 0 and PIC1 of MX204 router. You are not limited to configure only the below mentioned example port configurations. For more valid port configuration values, refer port-checker tool.

PTX10003 Router Port Speed Overview

PTX10003 Packet Transport Routers feature flexible interface configuration options with universal multi-rate double-density Quad Small Form-factor Pluggable (QSFP-DD) optics. The PTX10003-80C port panel has 40 physical ports and the PTX10003-160C port panel has 80 physical ports. The physical ports are in groups of five QSFP-DD ports. You can configure different data rates for each port group as long as the specified guidelines are met. Any port can be used as a 100-Gigabit Ethernet interface, 40-Gigabit Ethernet interface, 25-Gigabit Ethernet interface, or 10-Gigabit Ethernet interface. You choose the speed by plugging in the appropriate transceiver.

Note:

The center port in each port group (port 2 and port 7) cannot support 1x200 Gbps. To configure a 200 Gbps data rate for those ports, you’ll need to configure them as 2x100 Gbps. For more details, see Understanding QSFP-DD Interfaces and Configurations. Also, only ports 0,4,5, or 9 on each PIC can support 400 Gbps or 4x100 Gbps. To configure the speed, you must plug in the appropriate transceiver and configure the speed.

You can channelize the Gigabit Ethernet interfaces on PTX10003 routers to create multiple independent Gigabit Ethernet interfaces and then use breakout cables to connect the channelized ports to other servers, storage devices, and routers. Here’s the allowable channelization configurations for the optical transceivers supported by the PTX10003:

Note:

For more details about supported transceivers and cable specifications, see the PTX10003 Packet Transport Router Hardware Guide .

By default, all PTX10003 QSFP-DD interfaces are configured for a data rate of 2x100 Gbps. The interface names appear in the et-fpc/pic/port:channel format.

The port speed can be configured at the PIC-level by using the set chassis fpc slot-number pic slot-number pic-mode pic-mode command. The pic-mode statement can take values 10G, 40G, or 100G to operate all ports in 4x10G, 1x40G, or 1x100G.

To configure the port speed or channelize a port:

  1. Issue the following command to set the port speed: set chassis fpc slot-number pic pic-number port port-number number-of-subports [1 | 2| 4  |8] speed [10G | 40G | 100G |200G |400G]

    For example, to configure the second port in the first port group as a 1x40 Gbps interface, issue the set chassis fpc 0 pic 0 port 1 number-of-subports 1 speed 40g command.

  2. Type the commit command.

    After you commit this configuration, the second port in PIC 0 will operate at 1x40 Gbps.

    Note:

    When a port speed and sub-port-number are configured, the configured values override the default port speed for the transceiver. If you try to configure a port speed that is not supported by the transceiver, the port will be disabled. If there isn’t a port speed configured on a valid optical port, the PTX10003 uses a default port speed of 2x100 Gbps. Also, if number-of-subports is not configured, a 1x 40G | 100G |200G |400G] data rate is assumed. A 1x10G sub-port is not supported.

    When a port is channelized, the interface name has a colon followed by the port channel to signify the four separate channels. For example, on a PTX10003 with port 2 on PIC 1 configured as four 25-Gigabit Ethernet ports, the interface names are et-0/1/2:0, et-0/1/2:1, et-0/1/2:2, and et-0/1/2:3.

    There is no commit check when you channelize a port or configure the speed of the port.

PTX10K-LC1201 Port Speed Overview

The PTX10K-LC1201 line card is a fixed-configuration, rate-selectable line card with 36 built-in ports. The ports on the PTX10K-LC1201 are called rate-selectable or multi-rate ports as they support multiple port speeds. Rate selectability enables you to configure the port speed either at the port level or at the PIC level. To configure all ports to operate at the same speed, configure rate selectability at the PIC level, in which case you cannot configure the speed of individual ports. To configure rate selectability at the PIC level, use the pic-mode statement and specify the port speed. You can choose to configure all ports to operate at the same speed or configure all the ports to operate at different supported speeds. The default port speed is 400Gbps for all ports. Each PTX10K-LC1201provides a maximum bandwidth of 14.4Tbps.

On the PTX10K-LC1201, you can choose to configure all 36 ports with the following port speeds:

  • 4x10 Gbps, 4x25 Gbps, and 2x50 Gbps

  • 40 Gbps, 100 Gbps, 200 Gbps, and 400 Gbps

Note:

When you change the speed at the PIC level, the existing interfaces are deleted and new interfaces are created based on the new configuration. When you change the speed of a particular port explicitly by using the speed statement, only that port is affected. All other ports in that PIC remain unaffected.

For information about how to configure rate selectability, see Configuring Port Speed on PTX10K-1201 line card to Enable Different Port Speeds.

Table 78 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

Interface Naming Conventions

The interface name uniquely identifies an individual network connector in the system. Use the interface name when you configure the interface. Every device follows it own naming convention. Use this topic to understand more about the interface naming conventions for the line cards and devices.

Interface Naming Conventions for MPC7E-MRATE

MPC7E (MPC7E-MRATE) is a fixed-configuration MPC and contains two built-in PICs, PIC 0 and PIC 1. Each of the six ports of PIC 0 and PIC 1 support multiple port speeds of 100 Gbps, 40 Gbps, and 10 Gbps and can be configured as 10-Gigabit Ethernet and 40-Gigabit Ethernet interfaces. However, you can configure only ports 2 and 5 on both the PICs as 100-Gigabit Ethernet interfaces.

MPC7E-MRATE has an aggregate forwarding capacity of 480 Gbps and a forwarding capacity of 240 Gbps on each Packet Forwarding Engine. Oversubscription of Packet Forwarding Engine capacity is not supported. The demand on each Packet Forwarding Engine must be less than or equal to its forwarding capacity. For instance, for MPC7E-MRATE, the demand on each Packet Forwarding Engine must be less than or equal to 240 Gbps.

The 40-Gigabit Ethernet and 100-Gigabit Ethernet interfaces configured on the MPC7E-MRATE MPC follow the naming convention et-fpc-slot/pic-slot/port-number. The 10-Gigabit Ethernet interfaces configured on the MPC7E- MRATE MPC follow the naming convention xe-fpc-slot/pic-slot/port-number:[logical-port-number].

For example, et-0/0/2 indicates either a 40-Gigabit Ethernet or a 100-Gigabit Ethernet interface configured on port 2 of PIC 0 of the MPC7E-MRATE MPC that is installed in the MPC slot 0. xe-0/0/1:3 indicates a 10-Gigabit Ethernet interface configured on logical port 3 of physical port 1 of the MPC7E-MRATE MPC that is installed in the MPC slot 0.

Table 79 lists the naming conventions for interfaces on MPC7E-MRATE for MX240, MX480, MX960, MX2010, and MX2020 routers.

Interface Naming Conventions for MIC-MRATE

MIC-MRATE consists of twelve ports that support multiple port speeds of 100 Gbps, 40 Gbps, and 10 Gbps. MIC-MRATE is supported on MPC8E (MX2K-MPC8E) and MPC9E (MX2K-MPC9E) on MX2000 line of routers.

Starting with Junos OS Release 17.3R1, MIC-MRATE is supported on MX10003 MPC on MX10003 routers.

Note:

By default, the MIC-MRATE ports are configured as 10-Gigabit Ethernet ports.

MPC8E has a forwarding capacity of 240 Gbps for each Packet Forwarding Engine. In Junos OS Release 16.1R1 and later, you can upgrade MPC8E to provide an increased bandwidth of 1600 Gbps (1.6 Tbps), by using an add-on license. After you configure the bandwidth 1.6T statement, MPC8E provides an increased bandwidth of 1.6 Tbps. The forwarding capacity is increased to 400 Gbps for each Packet Forwarding Engine.

MPC9E has a forwarding capacity of 400 Gbps for each Packet Forwarding Engine. Packet Forwarding Engine oversubscription is not supported. So, demand on each Packet Forwarding Engine should be less than or equal to its forwarding capacity. For MPC8E, demand on each Packet Forwarding Engine should be less than or equal to 240 Gbps and for MPC9E, demand on each Packet Forwarding Engine should be less than or equal to 400 Gbps.

Note:

On MPC8E with MIC-MRATE, you can configure four ports as 100-Gigabit Ethernet interfaces. On MPC9E with MIC-MRATE and on MPC8E configured to operate at 1.6 Tbps by using an add-on license, you can configure eight ports as 100-Gigabit Ethernet interfaces.

The 40-Gigabit Ethernet and 100-Gigabit Ethernet interfaces configured on the MIC-MRATE MIC follow the naming convention et-fpc-slot/pic-slot/port-number. The 10-Gigabit Ethernet interfaces configured on the MIC-MRATE MIC follow the naming convention xe-fpc-slot/pic-slot/port-number:[logical-port-number].

For example, xe-0/0/1:3 indicates a 10-Gigabit Ethernet interface configured on logical port 3 of physical port 1 of the MIC-MRATE MIC that is installed in the MPC slot 0. The interface name et-0/0/2 indicates either a 40-Gigabit Ethernet interface or a 100-Gigabit Ethernet interface configured on port 2 of MIC-MRATE MIC that is installed in the MPC slot 0.

Table 80 lists the naming conventions used for interfaces on MIC-MRATE when installed on slot 0 of MPC8E and MPC9E. Table 81 lists the naming conventions used for interfaces on MIC-MRATE when installed on slot 1 of MPC8E and MPC9E. MPC8E and MPC9E support two MIC-MRATE MICs each.

Note:

The x in et-x/0/0 and xe-x/0/0:[0-3] refers to the MPC slot number.

Interface Naming Conventions for MX10003 MPC

The MX10003 MPC supports a Multi-Rate 12xQSFP28 Ethernet MIC (model numbers: JNP-MIC1 and JNP-MIC1-MACSEC) and the fixed-port PIC (6xQSFPP).

Each of the 6 ports of the PIC supports 10-Gigabit Ethernet and 40-Gigabit Ethernet interfaces. Each of the 12 ports of the modular MIC supports 10-Gigabit Ethernet, 40-Gigabit Ethernet, and 100-Gigabit Ethernet interfaces. All the ports of the modular MIC can be configured as 100-Gigabit Ethernet interfaces.

The 40-Gigabit Ethernet and 100-Gigabit Ethernet interfaces configured on the MX10003 MPC follow the naming convention et-fpc-slot/pic-slot/port-number. The 10-Gigabit Ethernet interfaces follow the naming convention xe-fpc-slot/pic-slot/port-number:[logical-port-number].

For example, xe-1/1/1:3 indicates a 10-Gigabit Ethernet interface configured on logical port 3 of physical port 1 of the modular MIC that is installed in the MPC slot 1. The interface name et-1/1/2 indicates either a 40-Gigabit Ethernet interface or a 100-Gigabit Ethernet interface configured on port 2 of modular MIC that is installed in the MPC slot 1.

Note:

The x in et-x/0/0 and xe-x/0/0:[0-3] refers to the MPC slot number.

Table 83 lists the naming conventions used for interfaces on the fixed-port PIC when installed in slot 0 of the MX10003 MPC. Table 84 lists the naming conventions used for interfaces on the modular MIC when installed in slot 1 of the MPC.
