Description

Display the state of the electrical switch fabric links between the Flexible PIC Concentrators (FPCs) and the Switch Interface Boards (SIBs). (PTX10002-36QDD devices only) Display peer FPC / Packet Forwarding Engine (PFE) details because the PFEs are directly connected to each other.

Options

none

Display the switch fabric link state.

extended

(Optional) Display the fabric link state for all 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.
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.
