Description

(M20, M40, M40e, M120, M160, M320, MX Series, and T Series routers, QFabric systems, EX Series switches, and PTX Series Packet Transport Routers only) Control the operation of the Flexible PIC Concentrator (FPC).

Note:

Starting with Junos OS Release 12.3, it is possible that FPCs brought offline by using the request chassis fpc slot fpc-slot offline operational-mode CLI command can come online during a configuration commit or power-supply replacement procedure. As an alternative, use the set fpc fpc-slot power off configuration-mode command at the [edit chassis] hierarchy level to ensure that the FPCs remain offline.

Note:

Starting in Junos OS Evolved Release 19.1R1, PTX10003-80C and PTX10003-160C devices do not support the request chassis fpc online command. The only way to bring up an FPC (MPC) that is offline is by rebooting the chassis.

On Junos OS Evolved, an FPC does not restart when you enter a commit command that configures an element of that FPC.

Note:

In releases earlier than Junos OS Release 15.1F3 and Junos OS Release 16.1, offline FPCs in the PTX5000 router might be powered on by the router during a reboot, or when triggered by other power management events on the router, such as when you take another FPC offline.

Starting with Junos OS Release 15.1F3 and Junos OS Release 16.1, offline FPCs do not come online during reboots or other power management events. To bring such an FPC online:

  1. Delete the fpc fpc-slot power off statement from the [edit chassis] hierarchy level, if that statement is configured, and commit the configuration.

  2. Either issue the request chassis fpc online slot fpc-slot operational-mode CLI command or press and hold the FPC ONLINE/OFFLINE button for about 5 seconds until the green OK LED next to the button lights steadily.

Note:

If a CLI-based firmware upgrade is in progress, the specified FPC does not restart. Starting with Junos OS Release 15.1, the following message is displayed when this occurs:

Note:

The command request chassis fpc (offline | online) slot slot-number is not supported on PTX1000 router. Whereas, request chassis fpc restart slot slot-number is supported on PTX1000 router

Note:

On EX9204, EX9208, EX9214, and EX9253 switches, when a line card is brought online, if the aggregate interface is initialized before the child interface is marked as part of the aggregate interface, there might be a loss of traffic from the aggregate interface for up to 30 seconds and the CPU usage of the line card installed on the switch might go up to 100%.

Options

offline

Take the FPC offline.
online

Bring the FPC online.
interconnect-device name

(QFabric systems only) Bring the FPC on the QFX3008-I Interconnect device either offline or online:

  • (QFabric System) On a QFabric system, specify the name of the QFX3008-I Interconnect device containing the FPC you want to bring either offline or online.
restart

Restart the FPC.
slot slot-number

FPC slot number:

  • M20 router—0 through 3.

  • M120 router—0 through 5.

  • MX240 router—0 through 2. On the MX240 router, slot-number corresponds to the (DPC slot number. If an MPC is installed, slot-number corresponds to the MPC slot number.

  • MX480 router—0 through 5. On the MX480 router, slot-number corresponds to the DPC slot number. If an MPC is installed, slot-number corresponds to the MPC slot number.

  • MX960 router—0 through 11. On the MX960 router, slot-number corresponds to the DPC slot number. If an MPC is installed, slot-number corresponds to the MPC slot number.

  • MX2020 router—0 through 19.

  • MX2010 router—0 through 9.

  • MX2008 router—0 through 9.

  • TX Matrix and TX Matrix Plus routers only—On the TX Matrix router, if you specify the number of the T640 router by using the lcc number option (the recommended method), replace slot-number with a value from 0 through 7. Otherwise, replace slot-number with a value from 0 through 31.

    Likewise, on a TX Matrix Plus router, if you specify the number of the T1600 or T4000 router by using the lcc number option (the recommended method), replace slot-number with a value from 0 through 7. Otherwise, replace slot-number with a value from 0 through 31. In case of TX Matrix Plus router with 3D SIBs, replace slot-number with a value from 0 through 63. For example, the following commands have the same result:

  • Other routers—0 through 7.

  • QFabric System—Replace slot-number with a value from 0 through 2.

  • EX Series switches:

    • EX4200 switches in a Virtual Chassis configuration—Replace slot-number with a value from 0 through 9.

    • EX6210 switches—Replace slot-number with a value from 0 through 9.

      Note:

      These commands are not supported for slots 4 and 5 when a Switch Fabric and Routing Engine (SRE) module is installed in those slots. These commands are supported for slots 4 and 5 only if a line card is installed in them.

    • EX8208 switches—Replace slot-number with a value from 0 through 7.

    • EX8216 switches—Replace slot-number with a value from 0 through 15.

    • EX9204 switches—Replace slot-number with a value from 0 through 2.

    • EX9208 switches—Replace slot-number with a value from 0 through 5.

    • EX9214 switches—Replace slot-number with a value from 0 through 11.

  • PTX5000 Packet Transport Router—Replace slot-number with a value from 0 through 7.
all-members

(MX Series routers only) (Optional) Change FPC status of all members of the Virtual Chassis configuration.
local

(MX Series routers only) (Optional) Change FPC status of the local Virtual Chassis member.
member member-id

(MX Series routers only) (Optional) Change FPC status of the specified member of the Virtual Chassis configuration. Replace member-id with a value of 0 or 1.
lcc number

(TX Matrix router and TX Matrix Plus router only) (Optional) Line-card chassis number.

Replace number with the following values depending on the LCC configuration:

  • 0 through 3, when T640 routers are connected to a TX Matrix router in a routing matrix.

  • 0 through 3, when T1600 routers are connected to a TX Matrix Plus router in a routing matrix.

  • 0 through 7, when T1600 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.

  • 0, 2, 4, or 6, when T4000 routers are connected to a TX Matrix Plus router with 3D SIBs in a routing matrix.
