show chassis fabric sibs

Syntax

show chassis fabric sibs<lcc number | scc>

Release Information

Command introduced before Junos OS Release 7.4.

Description

(TX Matrix routers only) Display the state of the electrical and optical switch fabric link between the SIBs in the TX Matrix router (TX-SIBs) and the SIBs in the T640 routers (T640 LCC SIBs).

(M320, T640, T1600, and T4000 routers) Display the state of the electrical switch fabric link between the SIBs and the FPCs.

Options

(M320, T640, T1600, and T4000 routers) Display the state of the electrical switch fabric link between the SIBs and the FPCs.

lcc number

—

(Optional) Display the switching fabric link state for the T640 SIBs on a specified T640 router (line-card chassis) connected to a TX Matrix router.

scc

—

(Optional) Display the switching fabric link state for the TX-SIBs on the TX Matrix router (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	Possible plane state of the M320 SIB, 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. S_EMPTY—No links are present on the SIB, and the fabric plane (SIB) is powered down. S_ACTIVATING—Links on the SIB are coming online; this is a transitional state. S_DEACTIVATING—Links on the SIB are going offline; this is a transitional state. S_FAULTING—Links on the SIB are being marked faulty, and the fabric plane (SIB) is not operational. S_FAULT—Links on the SIB are in an alarmed state, and the fabric plane (SIB) is not operational for the following reasons: On-board F-chip is not operational. Fiber optic connector faults. FPC connector faults.

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

Possible plane state of the M320 SIB, 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.
S_EMPTY—No links are present on the SIB, and the fabric plane (SIB) is powered down.
S_ACTIVATING—Links on the SIB are coming online; this is a transitional state.
S_DEACTIVATING—Links on the SIB are going offline; this is a transitional state.
S_FAULTING—Links on the SIB are being marked faulty, and the fabric plane (SIB) is not operational.
S_FAULT—Links on the SIB are in an alarmed state, and the fabric plane (SIB) is not operational for the following reasons:
- On-board F-chip is not operational.
- Fiber optic connector faults.
- FPC connector faults.
