show chassis fabric fpcs

Syntax

show chassis fabric fpcs <lcc number>

Release Information

Command introduced before Junos OS Release 7.4.

Description

(M320, MX Series, and T Series routers only) Display the state of the electrical and optical switch fabric links between the Flexible PIC Concentrators (FPCs) and the Switch Interface Boards (SIBs).

Options

none: Display the switch fabric link state. On a TX Matrix router, display the switching fabric link states for the FPCs in all T640 routers connected to the TX Matrix router. On a TX Matrix Plus router, display the switching fabric link states for the FPCs in all T1600 routers connected to the TX Matrix Plus router.
lcc number: (TX Matrix and TX Matrix Plus router only) (Optional) On a TX Matrix router, display the switch fabric link state for the FPCs in the specified T640 router (or line-card chassis) that is connected to the TX Matrix router. On a TX Matrix Plus router, display the switch fabric link state for the FPCs in the specified T1600 router (or line-card chassis) that is connected to the TX Matrix Plus router. Replace number with a value from 0 through 3.

Table 1: show chassis fabric fpcs Output Fields

Field Name	Field Description
Fabric management FPC state	Switching fabric link (link from SIB to FPC) state for each FPC: Unused—FPC is not present. Destination error on PFEs list of PFE numbers—Destination errors to the listed Packet Forwarding Engines. Indicates that the link is not carrying traffic to the listed Packet Forwarding Engines. Note: In Junos OS Release 9.6 and later, the list of Packet Forwarding Engines with destination errors is displayed in the output. In Junos OS Releases before 9.6, the output only indicates that there are destination errors. However, the list of Packet Forwarding Engines with destination errors is not displayed. Links ok—Link between the spare SIB and FPC is eligible to carry traffic. Link error—Link between the SIB and FPC has CRC errors. However, the link is still eligible to carry traffic. Plane disabled—Fabric plane has been disabled for the following reasons: Destination errors have exceeded the thresholds. Run-time link errors have exceeded the thresholds. Initialization time link errors detected, and link training was unsuccessful. Plane enabled—Link between the active SIB and FPC is eligible to carry traffic.

Field Name

Field Description

Fabric management FPC state

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

Unused—FPC is not present.
Destination error on PFEs list of PFE numbers—Destination errors to the listed Packet Forwarding Engines. Indicates that the link is not carrying traffic to the listed Packet Forwarding Engines.
Note: In Junos OS Release 9.6 and later, the list of Packet Forwarding Engines with destination errors is displayed in the output.
In Junos OS Releases before 9.6, the output only indicates that there are destination errors. However, the list of Packet Forwarding Engines with destination errors is not displayed.
Links ok—Link between the spare SIB and FPC is eligible to carry traffic.
Link error—Link between the SIB and FPC has CRC errors. However, the link is still eligible to carry traffic.
Plane disabled—Fabric plane has been disabled for the following reasons:
- Destination errors have exceeded the thresholds.
- Run-time link errors have exceeded the thresholds.
- Initialization time link errors detected, and link training was unsuccessful.
Plane enabled—Link between the active SIB and FPC is eligible to carry traffic.
