Syntax

Syntax (TX Matrix Router)

Syntax (TX Matrix Plus Router)

Description

(T Series routers only) Display Switch Processor Mezzanine Board (SPMB) Switch Interface Board (SIB) status information.

Options

none

(TX Matrix and TX Matrix Plus routers only) On a TX Matrix router, display the SIB status for the TX Matrix router and its attached T640 routers. On a TX Matrix Plus router, display the SIB status for the TX Matrix Plus router and its attached routers.
lcc number

(TX Matrix and TX Matrix Plus routers only) (Optional) On a TX Matrix router, display SIB status information for a specified T640 router (line-card chassis) that is connected to a TX Matrix router. On a TX Matrix Plus router, display SIB status information for a specified router (line-card chassis) that is connected to a TX Matrix Plus router.

Replace number with the following values depending on the LCC configuration:

  • 0 through 3, when T640 routers are connected to a TX Matrix router in a routing matrix.

  • 0 through 3, when T1600 routers are connected to a TX Matrix Plus router in a routing matrix.

  • 0 through 7, when T1600 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.

  • 0, 2, 4, or 6, when T4000 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.
scc

(TX Matrix router only) (Optional) Display SIB status information for the TX Matrix router (switch-card chassis).
sfc

(TX Matrix Plus router only) (Optional) Display SIB status information for the TX Matrix Plus router (or switch-fabric chassis).

Additional Information

On a T Series router, you can use either this command or the show chassis sibs command to produce the same output. The show chassis sibs command is supported on the M320 router and on the T Series routers.

Output Fields

Table 1 lists the output fields for the show chassis spmb sibs command. Output fields are listed in the approximate order in which they appear.

Table 1: show chassis spmb sibs Output Fields

Field Name

Field Description

Slot

SIB slot number:

  • T640 router, T1600 router or TX Matrix router—0 through 4

  • TX Matrix Plus router:

    • TXP-F13 SIB Slots—0 through 16

    • TXP-F2S SIB Slots —0 – 4/[0|2|4|6]

  • T320 router—0 through 2

State

SIB status:

  • Disconnected—SIBs on all T640 routers on the TX Matrix router (switch-card chassis) are in the Disconnected state, because a SIB on the SCC has gone offline. Likewise, SIBs on all T1600 or T4000 routers on the TX Matrix Plus router (or switch-fabric chassis) are in the Disconnected state, because a SIB on the SFC has gone offline.

  • Online—SPMB is operational and running.

  • Offline—SPMB is powered down.

  • Spare—SIB is redundant and will move to active state if one of the working SIBs fail to pass traffic.

  • Empty—No SPMB is present.

  • Fault— SIB is in alarmed state where the SIB’s plane is not operational for the following reasons:

    • On-board F-chip is not operational.

    • Fiber optic connector faults.

    • FPC connector faults.

    • SIB midplane connector faults.

  • Check—SIB is in alarmed state where the SIB’s plane is partially operational for the following reasons:

    • SIB is not inserted properly.

    • Two or more links between the SIB and PFE fails.

Uptime

How long the SIB has been up and running.
