Port Speed

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 2 describes the port speed configuration at PIC Level - Chassis Hierarchy.

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

• If an even port is configured in channelized mode (4x10G or 4x25G), then you cannot use the subsequent odd port and need to configure the port as unused.

Use the speed command to set the speed on tri-rate SFP port. To configure the speed of non-channelized interfaces, use Table 4. To configure the speed of channelized interfaces, use Table 5.

Table 1 summarizes the port speed support on ACX7024 routers.

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 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.

To view the supported transceivers, optical interfaces, and DAC cables on MPC7E-MRATE, see Hardware Compatibility Tool (HCT).

Table 32 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. Therefore, if you configure 100G as the operating speed of a PIC, the PIC is rebooted and the ports 0, 1, 3, and 4 are disabled. However, 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.

Table 35 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

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.

Table 38 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

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

• By default, all ports of the MIC-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 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.

• 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.

To view the supported transceivers, optical interfaces, and DAC cables on MX10003 MPC, see Hardware Compatibility Tool (HCT).

Table 43 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

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.

  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.

• 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.

To view the supported transceivers, optical interfaces, and DAC cables on MX204, see Hardware Compatibility Tool (HCT).

Table 50 summarizes the Packet Forwarding Engine mapping and the supported port speeds for MX204.

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.

Table 56 summarizes the supported port speeds on MX304 router.

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

• By default, the MX304 router comes up with PIC mode where all the interfaces operate at the same speed of 100 Gbps. By default, both the PICs (PIC0 and PIC1) operate at 100 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.

• By default, ports are configured in 100G pic-mode. When a specific port, such as port 0, is configured in 10G port-mode, only that port's IFD (Interface Definition) will be created based on the configuration. Other ports that do not have any configuration will not be created in any mode. To configure a port in port-mode, a speed configuration must be present for that port.

• 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.

• 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.

• 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 all ports in 100 Gbps at the same time.

• 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 100 Gbps, the port bounces back automatically. The 100-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 fpc continues to operate with the last available configuration. If the fpc is rebooted with Invalid configuration, the fpc move to the default mode.

• Starting in Junos OS Release 23.1R1, the MX304 supports 1G speeds in addition to the previously supported speeds of 400G, 100G, 40G, 25G, and 10G.

• Starting in Junos OS Release 23.2R1, the MX304 supports 1G Class-of-Service (Cos) on 1G ports.

Table 57 lists the interface naming conventions for MX304.

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

To view the supported transceivers, optical interfaces, and DAC cables on MIC-MACSEC-20GE, see Hardware Compatibility Tool (HCT).

Table 58 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

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.

Table 60 summarizes the Packet Forwarding Engine mapping and the supported port speeds.

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 64 for list of supported active ports on MPC10E-10C-MRATE.

• By default, the MPC10E-15C-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, PIC1 and PIC 2) 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 69 for list of supported active ports on MPC10E-15C-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.

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

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.
