show chassis fabric sibs

Syntax

show chassis fabric sibs <lcc number | scc>

Release Information

Command introduced before JUNOS Release 7.4.

Description

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

Between the Switch Interface Boards (SIBs) in the TX Matrix router (TX SIBs) and the SIBs in the T640 routers (T640 SIBs).
Between the T640 SIBs and the Flexible PIC Concentrators (FPCs) in a T640 router.

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).

Output Fields

Table 68 lists the output fields for theshow chassis fabric sibs command. Output fields are listed in the approximate order in which they appear.

Table 68: show chassis fabric sibs Output Fields

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.

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.
