Description

(MX Series, QFabric systems, EX Series switches, and PTX Series Devices only) Control the operation of the Flexible PIC Concentrator (FPC). An error message is displayed when restart, offline, or online is configured using request chassis fpc slot command on an FPC with empty slot.

Control the operation of the Flexible PIC Concentrator (FPC).

Note:

The SRX5K-SPC-2-10-40 (SPC1), SRX5K-SPC-4-15-320 (SPC2), and SRX5K-SPC3 does not support the request chassis fpc command.

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.

  • Starting in Junos OS Evolved Release 19.1R1, PTX10003-80C and PTX10003-160C devices do not support the request chassis fpc slot <slot-number> online command. The only way to bring up an FPC (MPC) that is offline is by rebooting the chassis. So, starting in Junos OS Evolved Release 21.1R1, when you take an FPC offline by using the request chassis fpc slot <slot-number> offline command, the screen displays the following message.

    Warning : FPC <slot> cannot be made online using a CLI command. You need to perform router reboot using "request system reboot" to online the FPC <slot>. Do you wish to continue ? [yes,no] (no).

    Starting in Junos OS Evolved Release 22.4R1, when you perform FPC restart by using the request chassis fpc slot <slot-number> offline command, the screen displays the following message.

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:

content_copy zoom_out_map
user@host> request chassis fpc slot 0 restart
FPC 0 Firmware update in progress. Wait!!!
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

node

Change Flexible PIC Concentrator status of specific node.

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.

force

Restart an unresponsive FPC on PTX platforms. The <force> option can be used before or after the <(offline | online | restart)> options

slot slot-number

The following options can be configured for FPC slots:

  • offline —Take the FPC slot offline.

  • online — Bring the FPC slot online.

  • restart — Restart the FPC slot.

FPC slot number:

  • 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.

  • MX10004 router—0 through 3.

    MX10008 router—0 through 7.

    MX10016 router—0 through 15.

  • 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.

tag This option is used for upgrading the latest firmware for components Mezz, I2CS, CPLD or Boot CPLD on the FPC.
pfe-instance pfe-number PFE instance number for the FPC slot. For PTX10008 device, it is 0 through 4.

The following options can be configured for PFEs:
