Interface Naming Conventions for Rate Selectability

 

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 rate selectability.

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 1 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 2 lists the naming conventions used for interfaces on MIC-MRATE when installed on slot 0 of MPC8E and MPC9E. Table 3 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 JNP10K-LC2101

JNP10K-LC2101 is a is a fixed-configuration MPC and contains six built-in PICs, PIC 0 to PIC 5. Each PIC supports 4 ports. All ports support multiple port speeds of 100 Gbps, 40 Gbps, and 10 Gbps and can be configured as 10-Gigabit Ethernet, 40-Gigabit Ethernet, and 100-Gigabit Ethernet interfaces.

JNP10K-LC2101 has a forwarding capacity of 240 Gbps for each Packet Forwarding Engine. JNP10K-LC2101 has six Packet Forwarding Engines. In Junos OS Release 18.2R1 and later, you can upgrade JNP10K-LC2101 to provide an increased bandwidth of 2400 Gbps (2.4Tbps), by using an add-on license. After you configure the bandwidth 2.4T statement, JNP10K-LC2101 provides an increased bandwidth of 2.4 Tbps. The forwarding capacity is increased to 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.

The 40-Gigabit Ethernet and 100-Gigabit Ethernet interfaces configured on the JNP10K-LC2101 MPC follow the naming convention et-fpc-slot/pic-slot/port-number. The 10-Gigabit Ethernet interfaces configured on the JNP10K-LC2101 MPC 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 JNP10K-LC2101 MPC 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 the JNP10K-LC2101 MPC that is installed in the MPC slot 0.

Note

Each Packet Forwarding Engine maps to a single built-in PIC on the JNP10K-LC2101.

Table 7 lists the naming conventions used for interfaces on JNP10K-LC2101 for MX10008 routers. MX10008 routers support 8 JNP10K-LC2101 MPCs.

Interface Naming Conventions for MPC10E-15C-MRATE MPC

Starting with Junos OS Release 19.1R1, the MPC10E-15C-MRATE (15x100G) is introduced for MX240, MX480, MX960 platforms, that is capable of delivering up to 1.5 terabits per-slot bandwidth. The MPC10E-15C-MRATE consists of three Packet Forwarding Engines (PFE) per MPC and each PFE is capable of delivering up to 500Gbps throughput. It supports three PICs per MPC, that is, one PIC per PFE, and five ports per PIC (that is, fifteen ports per MPC). Each PIC contains 5xQSFP28 ports that supports 100-Gbps, 40-Gbps, and 10-Gbps speeds using QSFP56-DD, QSFP28, and QSFP+ optics. The 10-Gbps speed is supported by using break out cables.

Starting with Junos OS Release 19.3R1, you can now configure 25-Gbps speed on any of the fifteen ports on the MPC10E-15C-MRATE.

Note
  • MPC10E-15C-MRATE is only supported on MX240, MX480, MX960 routers and not on MX2000 series and MX10000 lines of routers.

  • If you install the MPC10E-15C-MRATE, then the Switch Control Board MX-SCBE3 must be installed in the router in order for the MPC10E-15C-MRATE to come online.

  • By default, the MPC10E-15C-MRATE ports are configured as 100-Gigabit Ethernet ports.

The interface names for the 10-Gigabit Ethernet interfaces uses the prefix xe- while the interface names for 25, 40 and 100 interfaces uses the prefix et-. When multiple interfaces (or IFDs) are supported in a physical port, the colon (:) notation is used in the interface naming conventions (Example: 4x10GE interfaces). The colon (:) is used as a delimiter to differentiate the multiple interfaces (or IFDs) in a physical port.

By default, the 400-Gigabit Ethernet, 100-Gigabit Ethernet, 40-Gigabit Ethernet, and 25-Gigabit Ethernet interfaces appear in the et-fpc/pic/port format. When the 40-Gigabit Ethernet interfaces are channelized as 10-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format, where channel can be a value of 0 through 3. Similarly, when the 100-Gigabit Ethernet interfaces are channelized as 25-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format, where channel can be a value of 0 through 3.

Note

In the interface naming convention et-x/y/z and xe-x/y/z:[0-3] :

  • x refers to the FPC slot number.

  • y refers to the PIC slot number. The valid range is 0 to 2.

  • z refers to the physical port number. The valid range is 0 to 4.

Interface Naming Conventions for MPC10E-10C-MRATE MPC

Starting with Junos OS Release 19.2R1, the MPC10E-10C-MRATE (10x100G) is introduced for MX240, MX480, MX960 platforms, that is capable of delivering up to 1 terabits per-slot bandwidth. The MPC10E-10C-MRATE consists of two Packet Forwarding Engines (PFE) per MPC and each PFE is capable of delivering up to 500Gbps throughput. It supports two PICs per MPC, that is, one PIC per PFE, and five ports per PIC (that is, ten ports per MPC). Each PIC contains 5xQSFP28 ports that supports 100-Gbps, 40-Gbps, 25-Gbps, and 10-Gbps speeds using QSFP56-DD, QSFP28 and QSFP+ optics. The 10-Gbps and 25-Gbps speed is supported by using break out cables.

Starting with Junos OS Release 19.3R1, you can now configure 25-Gbps speed on any of the ten ports on the MPC10E-10C-MRATE.

Note
  • MPC10E-10C-MRATE is only supported on MX240, MX480, MX960 routers and not on MX2000 series and MX10000 lines of routers.

  • If you install the MPC10E-10C-MRATE, then the Switch Control Board MX-SCBE3 must be installed in the router for the MPC10E-10C-MRATE to come online.

  • By default, the MPC10E-10C-MRATE ports are configured as 100-Gigabit Ethernet ports.

The interface names for the 10-Gigabit Ethernet interfaces uses the prefix xe- while the interface names for 40, 100, and 400 interfaces uses the prefix et-. When multiple interfaces (or IFDs) are supported in a physical port, the colon (:) notation is used in the interface naming conventions (Example: 4x10GE interfaces). The colon (:) is used as a delimiter to differentiate the multiple interfaces (or IFDs) in a physical port.

By default, the 100-Gigabit Ethernet, 40-Gigabit Ethernet, 25-Gigabit Ethernet interfaces appear in the et-fpc/pic/port format. When the 40-Gigabit Ethernet interfaces are channelized as 10-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format, where channel can be a value of 0 through 3. Similarly, when the 100-Gigabit Ethernet interfaces are channelized as 25-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format, where channel can be a value of 0 through 3.

Interface Naming Conventions for MIC-MACSEC-20GE

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

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).

Note

In the 10G mode, only the marked ports are operational and other physical ports are disabled.

You should use the pic-mode 10G configuration command to set the PIC to operate in 10G mode. Both the PICs on a MIC must be configured in the same pic-mode, otherwise the configuration does not take effect. A chassis alarm is raised indicating a mis-configuration. Any mis-configuration will cause the PICs to assume default pic-mode, that is, to be in 20x1GE where all ports are in 1GE port speed.

Note

The 10-Gbps-capable ports (ports 8 and 9) of the 2x10GE/20x1GE MIC-MACSEC-20GE may show the link status as up while the peer side is down. In this case, it is recommended to disable auto-negotation and set the speed to 1-Gbps on the peer side to bring the link up on the peer side.

The MIC-MACSEC-20GE MIC also 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 distributes 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.

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 a reboot.

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

Understanding Interface Naming Conventions for MX2K-MPC11E MPC

Starting with Junos OS Release 19.3R2, the MX2K-MPC11E is introduced for MX2010 and MX2020 routers. The MX2K-MPC11E is a fixed-configuration modele port concentrator (MPC) which delivers bandwidth up to 4 Tbps per MPC slot. The MX2K-MPC11E has eight packet forwarding engines, each capable of delivering up to 500 Gbps throughput. The MX2K-MPC11E supports eight PICs—one PIC per PFE. There are five ports per PIC for a total of 40 ports per MX2K-MPC11E. Each PIC contains 5xQSFP28 ports. The default speed for all ports is 100-Gbps. Port 0 of each PIC supports 100-Gbps, 40-Gbps, and 4x10-Gbps speeds using QSFP28, QSFP+ optics. The 4x10-Gbps speed is supported by using break out cables.

Note
  • The MX2K-MPC11E supports only MX2010 and MX2020 routers.

  • The MX2K-MPC11E supports only MX2000-SFB3 switch fabric boards. It does not support SFB1 or SFB2. The router must have at least one MX2000-SFB3 to power on.

  • By default, the MX2K-MPC11E ports are configured as 100-Gigabit Ethernet ports.

The interface names for the 10-Gigabit Ethernet interfaces uses the prefix xe- while the interface names for 40-Gigabit Ethernet interfaces and 100-Gigabit Ethernet interfaces uses the prefix et-. When multiple interfaces are supported on a physical port, the colon (:) notation is used in the interface naming conventions (Example: 4x10GE interfaces). The colon (:) is used as a delimiter to differentiate the multiple interfaces on a physical port.

By default, the 100-Gigabit Ethernet and 40-Gigabit Ethernet interfaces appear in the et-fpc/pic/port format. When the 40-Gigabit Ethernet interfaces are channelized as 10-Gigabit Ethernet interfaces, the interface names appear in the xe-fpc/pic/port:channel format, where channel can be a value of 0 through 3.

Note

In the interface naming convention et-x/y/z and xe-x/y/z:[0-3] :

  • x refers to the FPC slot number. The valid range is 0 through 19.

  • y refers to the PIC slot number. The valid range is 0 through 7.

  • z refers to the physical port number. The valid range is 0 through 4.

Table 11 lists the interface naming conventions for the MX2K-MPC11E.

Interface Naming Conventions for JNP10K-LC1201

JNP10K-LC1201 is a is a fixed-configuration line card and contains 36 built-in ports. All ports support multiple port speeds of 400 Gbps, 200 Gbps, 100 Gbps, 50 Gbps, 40 Gbps, 25 Gbps and 10 Gbps and can be configured.

All the supported interfaces configured on the JNP10K-LC1201 line card follow the naming convention et-fpc-slot/pic-slot/port-number:channel where:

  • Valid range for the FPC is 0 through 7.

  • Valid range for the PIC is 0

  • Valid range for the port is 0 through 35.

  • Valid range for the channel is 0 through 7.

For example, the interface name et-0/0/2 indicates any Gigabit Ethernet interface configured on port 2 of the JNP10K-LC1201 line card that is installed in the FPC slot 0.

Table 12 lists the naming conventions used for interfaces on JNP10K-LC1201 for PTX10008 and PTX10016 routers. PTX10008 routers support 8 JNP10K-LC1201 line cards. PTX10016 routers support 16 JNP10K-LC1201 line cards.

Interface Mapping and Modulation Format for ACX5448-D

ACX5448-D routers support two CFP2-DCO optical modules (transceivers). For each optical module, one optical transport (ot-) interface is created. Thus, two ot- interfaces are created on this router. The ACX5448-D supports 100-Gigabit Ethernet (et-) interfaces. Two et- interfaces can be mapped to one ot- interface, depending on the rate (100 Gbps or 200 Gbps) that you configured for the CFP2 ports.

The optical interface to Ethernet interface mapping is displayed in the following table:

The port panel of the ACX5448-D presents 36 SFP+ ports (0-35), two QSFP28 ports (36 and 37), and two CFP2-DCO ports (38 and 39). The port to logical PIC mapping is as follows:

  • 0 to 35 ports represent PIC 0.

  • 36 and 37 ports represent PIC 1.

  • 38 and 39 ports represent PIC 2.

The QSFP28 port 36 (interface et-0/1/0) and the CFP2 port 38 (interface et-0/2/0) operate as multiplexer (also called mux) ports. Depending on the port speeds that you configure, the following behavior is observed:

  • If you configure 8QAM or 16QAM modulation (200 Gbps) on ot-0/2/0 (port 38), the et-0/1/0 interface (port 36) is deleted.

  • If you configure QPSK modulation (100 Gbps) on ot-0/2/0 (port 38), then et-0/2/1 on port 38 is disabled and et-0/1/0 on port 36 is enabled. This means you can operate the multiplexed ports 36 (QSFP28) and 38 (CFP2) at 100-Gbps speeds.

When you start up the router, the two Ethernet interfaces on port 36 are disabled by default. However, the interface et-0/2/0 (on port 38) is always available. You can enable the et-0/1/0 interface (on port 36) by running the set chassis fpc 0 cfp-to-et command and restarting the chassis-control (You can restart the chassis control by using the restart chassis-control command). (This configuration deletes the interface et-0/2/1 on port 38.) You can then multiplex interfaces et-0/1/0 (port 36) and et-0/2/0 (port 38) for a 200-Gbps operation. For more information on mux ports refer to Port Panel of an ACX5448-D Router.
