TX Matrix Plus Router Chassis and Interface Names

 

The output from some CLI commands uses the terms SFC and sfc (for switch-fabric chassis) to refer to the TX Matrix Plus router. Similarly the terms LCC, and lcc as a prefix (for line-card chassis) refer to a T1600 or T4000 router in a routing matrix composed of a TX Matrix Plus router and T1600 or T4000 routers.

T1600 routers are assigned LCC index numbers, 0 through 3, when T1600 routers are connected to a TX Matrix Plus router in a routing matrix. T1600 routers are assigned LCC index numbers, 0 through 7, when T1600 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix. The current supported configuration of the routing matrix, can have up to eight T1600 routers, and each T1600 router has up to eight FPCs. Therefore, the routing matrix can have up to 64 FPCs (0 through 63). The FPCs are configured at the [edit chassis lcc number] hierarchy level.

In the Junos OS CLI, an interface name has the following format:

When you specify the FPC number, the Junos OS determines which T1600 router contains the specified FPC based on the following assignment:

  • On LCC 0, FPC hardware slots 0 through 7 correspond to FPC software numbers 0 through 7.

  • On LCC 1, FPC hardware slots 0 through 7 correspond to FPC software numbers 8 through 15.

  • On LCC 2, FPC hardware slots 0 through 7 correspond to FPC software numbers 16 through 23.

  • On LCC 3, FPC hardware slots 0 through 7 correspond to FPC software numbers 24 through 31.

  • On LCC 4, FPC hardware slots 0 through 7 correspond to FPC software numbers 32 through 39.

  • On LCC 5, FPC hardware slots 0 through 7 correspond to FPC software numbers 40 through 47.

  • On LCC 6, FPC hardware slots 0 through 7 correspond to FPC software numbers 48 through 55.

  • On LCC 7, FPC hardware slots 0 through 7 correspond to FPC software numbers 56 through 63.

To convert FPC numbers in the T1600 routers to the correct FPC in a routing matrix, use the conversion chart shown in Table 1. You can use the converted FPC number to configure the interfaces on the TX Matrix Plus router in your routing matrix.

For example, in a routing matrix that contains lcc 0 through lcc 2, so-20/0/1 refers to FPC slot 4 of lcc 2.

T4000 routers are assigned LCC index numbers, 0, 2, 4, and 6 when T4000 routers are connected to a TX Matrix Plus router in a routing matrix. The current supported configuration of the routing matrix, can have up to four T4000 routers, and each T4000 router has up to eight FPCs. Therefore, the routing matrix can have up to 32 FPCs (0 through 63). The odd numbered LCCs and the FPC slots of these LCCs are unused, when T4000 routers are connected to TX Matrix Plus router in a routing matrix. The FPCs are configured at the [edit chassis lcc number] hierarchy level.

In the Junos OS CLI, an interface name has the following format:

When you specify the FPC number, the Junos OS determines which T4000 router contains the specified FPC based on the following assignment:

  • On LCC 0, FPC hardware slots 0 through 7 correspond to FPC software numbers 0 through 7.

  • On LCC 2, FPC hardware slots 0 through 7 correspond to FPC software numbers 16 through 23.

  • On LCC 4, FPC hardware slots 0 through 7 correspond to FPC software numbers 32 through 39.

  • On LCC 6, FPC hardware slots 0 through 7 correspond to FPC software numbers 48 through 55.

To convert FPC numbers in the T4000 routers to the correct FPC in a routing matrix, use the conversion chart shown in Table 2. You can use the converted FPC number to configure the interfaces on the TX Matrix Plus router in your routing matrix.
