Command introduced before JUNOS Release 7.4.

Description

(T Series routers only) Display the state of the electrical and optical switch fabric links:

Options

none — Display the switching fabric link state for the TX SIBs in the TX Matrix router and for the T640 SIBs in all the T640 routers connected to a TX Matrix router.

lcc number — (Optional) Display the switching fabric link state for the T640 SIBs in a specified T640 router (or line-card chassis) connected to a TX Matrix router. Replace number with a value from 0 through 3.

scc — (Optional) Display the switching fabric link state for the TX SIBs on the TX Matrix router (or switch-card chassis).

Field Name

Field Description

Fabric management SIB state

Switching fabric link state for each FPC:

  • Unused—FPC is not present.
  • Links ok—Link between the SIB and FPC is active.
  • Link error—Link between the SIB and FPC is not operational.

Plane state

State of the TX SIB or T640 SIB:

  • S_ACTIVE — Links on SIB are operational and the fabric plane (SIB) is operational and running.
  • S_SPARE—Links on SIB are operational and the fabric plane (SIB) is redundant and can be operational if any of the fabric planes in S_ACTIVE state encounters an error.
