show chassis fabric sibs

Syntax

show chassis fabric sibs <lcc number | scc>

Release Information

Command introduced before Junos OS 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).

Table 1: show chassis fabric sibs Output Fields

Field Name	Field Description
Fabric management SIB state	Switching fabric link (link from FPC to SIB) state for each SIB: Unused—SIB is not present. Links ok—Link between the SIB and the FPC is active. Link error—Link between the SIB and the FPC is not operational.
Plane state	In a routing matrix composed of the TX Matrix router, state of the TX SIB or T640 SIB: S_ACTIVE—Links on the SIB are operational, and the fabric plane (SIB) is operational and running. S_SPARE—Links on the SIB are operational and the fabric plane (SIB) is redundant and can be operational if any of the fabric planes in the S_ACTIVE state encounters an error. Note: If the plane is unusable by any of the Packet Forwarding Engines, the command output displays an additional string, plane has link errors on # pfes, where, # indicates the total number of links (both from SIB to FPC, and from FPC to SIB) having link errors (detected either during initialization time or runtime) in this particular plane. This does not count links having destination errors.

Field Name

Field Description

Fabric management SIB state

Switching fabric link (link from FPC to SIB) state for each SIB:

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

Plane state

In a routing matrix composed of the TX Matrix router, state of the TX SIB or T640 SIB:

S_ACTIVE—Links on the SIB are operational, and the fabric plane (SIB) is operational and running.
S_SPARE—Links on the SIB are operational and the fabric plane (SIB) is redundant and can be operational if any of the fabric planes in the S_ACTIVE state encounters an error.
Note: If the plane is unusable by any of the Packet Forwarding Engines, the command output displays an additional string, plane has link errors on # pfes, where, # indicates the total number of links (both from SIB to FPC, and from FPC to SIB) having link errors (detected either during initialization time or runtime) in this particular plane. This does not count links having destination errors.
