Displaying the Status of the Switching Fabric Topology of a Routing Matrix with a TX Matrix Plus Router

In a routing matrix with a TX Matrix Plus router, each of the five control planes contains various types of Switch Interface Boards (SIBs) that forward packets from a source Packet Forwarding Engine to a destination Packet Forwarding Engine.

You can use the show chassis fabric topology operational command to check the status of the SIB connections between the TX Matrix Plus router and the connected T1600 routers:

  • To display the fabric topology states for the entire routing matrix, issue the show chassis fabric toplogy command. To limit the command output to a particular TXP-F13 SIB, also include the SIB slot number as a command option.
  • To display the fabric topology states for the TX Matrix Plus router, include the sfc number option. To further limit the command output to a particular TXP-F13 SIB, also include the SIB slot number as a command option.
  • To display the fabric topology states for a particular T1600 router, include the lcc lcc-number option. To further limit the command output to a particular TXP-F13 SIB, also include the SIB slot number as a command option.

To display the fabric topology state for the TX Matrix Plus router only, issue the show fabric topology command with the sfc option. The command output displays the fabric link status for transmit-side links and receive-side links for each of the 16 TXP-F13 SIB slots in the TX Matrix Plus router. For every TXP-F13 SIB, the following information is listed:

  • Transmit-side link status—The state of each link from the TXP-F13 SIB to the TXP-T1600 SIB on a directly connected T1600 router. A TXP-F13 SIB connects to 2 different T1600 routers, and each connection consists of 128 links.
  • Receive-side link status—The state of each link to the TXP-F13 SIB from the TXP-T1600 SIB on a directly connected T1600 router.
