Syntax

content_copy zoom_out_map
request chassis fabric plane plane-number  (offline | online)

Description

(M120 and MX Series routers and EX8200 switches only) Control the operation of the specified fabric plane.

On an MX480 or MX240 series router, you can configure the active control board for redundancy mode or increased bandwidth mode. When running in increased bandwidth mode, MX series routers with Trio chips and the MPC3E will use all eight active fabric planes.

To take both plane 0 and plane 1 offline on a MX480 and MX240 series routers with one or more MPC4E MICs installed, a X86 Media Service Blade, and/or 100G PFE, and where redundancy-mode is configured for "increased-bandwidth", Juniper recommends taking plane 1 offline before plane 0. Likewise, when the router is configured for increased-bandwidth mode, taking fabric planes 0, 2, 4, and 6 offline can cause the chassis to run in a reduced fabric bandwidth mode. Plane 7 may remain in a "spare" state (as seen in the "show chassis fabric summary" command output) until plane 3 is taken offline and then brought back up.

Options

offline

Take the fabric plane offline. Use the request chassis fabric plane plane-number offline command to clear a FAULT state on a fabric plane. To bring the fabric plane back online, use the request chassis fabric plane plane-number online command.

online

Bring the fabric plane online.

plane plane-number

Fabric 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 MX2020, MX2010, and MX2008 routers, replace plane-number with a value from 0 through 7.

  • For the MX960, MX10004, and MX10008 routers, replace plane-number with a value from 0 through 11.

  • 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.
