Syntax

Syntax (MX Series Router)

Description

(M120 and MX Series routers and EX8200 switches only) On the M120 router, display the state of the switching fabric map for connections from the Forwarding Engine Boards (FEBs) to the ports on the fabric planes, as interpreted by the fabric plane. On the MX Series router and the EX8200 switch, display the state of the switching fabric map for connections from each Packet Forwarding Engine on the Dense Port Concentrators (DPCs) to the ports on the fabric planes, as interpreted by the fabric plane. For information about the meaning of “fabric plane”, “DPCs”, and “SIBs” on the switches, see the hardware documentation for your switch.

Options

none

Display the switching fabric map state for the M120 or MX Series router or EX8200 switch.

all-members

(MX Series routers only) (Optional) Display the switching fabric map state for all the members of the Virtual Chassis configuration.

local

(MX Series routers only) (Optional) Display the switching fabric map state for the local Virtual Chassis member.

member member-id

(MX Series routers only) (Optional) Display the switching fabric map state for the specified member of the Virtual Chassis configuration. Replace the member-id with a value of 0 or 1.

plane plane-number

(Optional) Display the state of the fabric link for the specified plane number.

  • For the M120 router, replace plane-number with a value from 0 through 3.

  • For the MX480 and MX240 routers, replace plane-number with a value from 0 through 7.

  • For the MX960 router, replace plane-number with a value from 0 through 5.

  • For the EX8208 switch, replace plane-number with a value from 0 through 11.

  • For the EX8216 switch, replace plane-number with a value from 0 through 7.

Table 1: show chassis fabric map Output Fields

Field Name

Field Description

in-links

Fabric map for receive side links.

out-links

Fabric map for transmit side links.

state

State of the fabric link:

  • RESET—Link between SIB and FPC/DPC is powered down on purpose. This is done in all non-dual PFE based boards.

  • UP—Link between SIB and FPC/DPC is up and running.

  • DOWN—Link between SIB and FPC/DPC is powered down.

  • FAULT—SIB is in alarmed state where the SIB’s plane is not operational for the following reasons:

    • On-board F-chip is not operational.

    • Fiber optic connector faults.

    • FPC connector faults.

    • SIB midplane connector faults.

Sample Output

show chassis fabric map (MX480 Router)

This sample applies to Junos OS Releases 18.2R2, 18.3R2, and 18.4R1 and later, in which the output of the CLI command show chassis fabric map, on MX series routers carrying MPCs with SF and XF ASICs, uses the label FPC instead of DPC (for example, 'FPC5PFE0').
