Description

Display the state of the electrical 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 routers connected to the TX Matrix Plus router.

extended

(MX2020 and MX2010 Routers with SFB2) (Optional) Display the fabric link state for all 24 fabric planes.
all-members

(MX Series routers only) (Optional) Display the switching fabric link states for the FPCs in all members of the Virtual Chassis configuration.
lcc number

(TX Matrix router 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 (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 router (line-card chassis) that is connected to the TX Matrix Plus router. Replace number with a following value depending on the LCC configurations:

  • From 0 through 3 on a T640 router on the routing matrix with TX Matirx routers.

  • From 0 through 3 on a T1600 router on the routing matrix with TX Matirx Plus routers.

  • From 0 through 7 on a T1600 router in a routing matrix with TX Matrix Plus router with 3D SIBs.

  • 0, 2, 4, 6 on a T4000 router in a routing matrix with TX Matrix Plus router with 3D SIBs.
local

(MX Series routers only) (Optional) Display the switching fabric link states for the FPCs in the local Virtual Chassis member.
member member-id

(MX Series routers only) (Optional) Display the switching fabric link states for the FPCs in the specified member of the Virtual Chassis configuration. Replace member-id with a value of 0 or 1.
slot fpc-slot (Optional)

(PTX Series Packet Transport Routers and QFX Series switches only) (Optional) Display the fabric state of the specified FPC slot. If no value is provided, display the status of all FPCs. The FPC slots range from 0-7 in PTX10008 and 0-15 in PTX10016.

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.

    (On MX240 and MX480 routers with AS- MLC modular carrier card or MPC4E only) the fabric plane from the pair that share physical links (1 and 5, and 3 and 7) is inactive.

  • 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 Disabled, Links Error (PTX Series Packet Transport Routers and QFX Series switches only)—The plane is disabled because of link errors detected at the FPC RX.

  • Plane Disabled, Links Down (PTX Series Packet Transport Routers and QFX Series switches only)—The plane is disabled because of link errors detected at the SIB RX.

  • Plane enabled—Link between the active SIB and FPC is eligible to carry traffic.

    Note:

    On the Enhanced MX SCB with MPC, a maximum of 4 planes are operational and running. On all the other SCBs with MPC, all the planes are operational and running.

  • Plane Enabled, Links OK (PTX Series Packet Transport Routers and QFX Series switches only)—The FPC CCL RX link is eligible to carry traffic.

  • Plane Enabled, Links OK (TX Matrix and TX Matrix Plus routers only)—The FPC HSL RX link is eligible to carry traffic.

The output of the show chassis fabric fpcs command is modified to include ASIC information. In the earlier releases, this command displayed ASICs as FCOREs. With this modification, for every FPC and SIB, information about ASIC and FCORE is presented separately in the output. For PTX10008, the ASIC numbering is 0-2 and for PTX10016, ASIC numbering is 0-5.
