Enabling and Disabling Hardware Components of a Routing Matrix with a TX Matrix Plus Router

You can temporarily disable certain hardware components (such as FPCs, PICs, and SIBs) that belong to the TX Matrix Plus router and T1600 or T4000 routers in the routing matrix. To do so, issue the appropriate request chassis command and include the sfc or lcc option as needed.

Note: If you issue a chassis-related command that references FPCs, we recommend that you use the FPC hardware slot number (0 through 7) of the specific T1600 router and specify its corresponding LCC number.

user@host> request chassis ?

The routing matrix extends the concept of taking specific hardware components offline or online to include an entire T1600 or T4000 router in a routing matrix. To enable or disable a T1600 or T4000 router in a routing matrix, issue the request chassis lcc slot lcc-number (offline | online) command:

Although you can enter the routing matrix-based slot number when you issue the request chassis fpc command, output from show chassis commands always references the FPC hardware slot number of the specific T1600 or T4000 router and its corresponding LCC number. As a result, we recommend that you include the FPC hardware slot number when you issue request chassis or show chassis commands, as shown in the following example.

First, issue the request chassis fpc command with the routing matrix-based FPC slot number of 19:

user@host> request chassis fpc offline slot 19
lcc2-re0:
--------------------------------------------------------------------------
Offline initiated, use "show chassis fpc" to verify

However, when you issue the show chassis fpc command to check the result, the output displays the change using node-centric terminology: FPC slot number 3 on T1600 router LCC2 (the equivalent of routing matrix slot 19).

To bring the same FPC back online, use the slot number and LCC number from the previous command output:

user@host> request chassis fpc online lcc 2 slot 3
lcc2-re0:
--------------------------------------------------------------------------
Online initiated, use "show chassis fpc" to verify

Once you bring the FPC back online, reissue the show chassis fpc command to see that the FPC slot and LCC number you used in the last command now matches the command output:

user@host> show chassis fpc
