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 router in a routing matrix composed of a TX Matrix Plus router and T1600 routers.
T1600 routers are assigned LCC index numbers, 0 through 3, depending on the hardware setup of the routing matrix. The current supported configuration of the routing matrix, can have up to four T1600 routers, and each T1600 router has up to eight FPCs. Therefore, the routing matrix can have up to 32 FPCs (0 through 31). 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.
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.

FPC Numbering | T1600 Routers | |||||||
|---|---|---|---|---|---|---|---|---|
| LCC 0 | ||||||||
| T1600 Router FPC Slots | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Routing Matrix FPC Slots Equivalent | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| LCC 1 | ||||||||
| T1600 Router FPC Slots | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Routing Matrix FPC Slots Equivalent | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
| LCC 2 | ||||||||
| T1600 Router FPC Slots | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Routing Matrix FPC Slots Equivalent | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 |
| LCC 3 | ||||||||
| T1600 Router FPC Slots | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Routing Matrix FPC Slots Equivalent | 24 | 25 | 26 | 27 | 28 | 29 | 30 | 31 |
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.
