    Configuring Graceful Switchover on the Line-Card Chassis

    Graceful switchover must be configured before you integrate an operational line-card chassis (LCC) with the TX Matrix Plus router. To prepare the LCC for graceful switchover:

    1. Verify that graceful switchover is enabled on the LCC by displaying its configuration at the [edit chassis redundancy graceful-switchover] hierarchy level:
      user@host> show configuration chassis redundancy graceful-switchover
      traceoptions {
          flag update;
      }
      enable;
      

      If graceful switchover is not enabled, enable it in configuration mode as follows:

      user@host# set chassis redundancy graceful-switchover enable

      For more information about graceful switchover, see the Junos OS High Availability Library for Routing Devices.

    2. Verify the state of the Packet Forwarding Engines by issuing the show pfe terse command on the master and backup Routing Engines:
      user@host> show pfe terse
      Slot Type Slot      State     Uptime
       0   GFPC Present   Online    03:46:19
       1   RE   Present   Online    03:47:09
      

      Verify that the State field of each Packet Forwarding Engine and the backup Routing Engine is Online.

      user@host> request routing-engine login other-routing-engine
      % cli
      user@host> show pfe terse
      Slot Type Slot      State     Uptime
       0   GFPC Present   Valid     03:46:19
      

      Verify that the State field of each Packet Forwarding Engine is Valid.

    3. Verify that the LCC Routing Engines are ready for a graceful switchover by issuing the show system switchover command on the backup Routing Engine:
      user@host> show system switchover
      Graceful switchover: On
      Configuration database: Ready
      Kernel database: Ready
      

      If the status of graceful switchover is not On, or the configuration and kernel database status are not Ready, see the Junos OS High Availability Library for Routing Devices for instructions. Do not continue integrating an operational LCC with the TX Matrix Plus router until the Routing Engines are ready for a graceful switchover.

    4. Log out of the backup Routing Engine:
      user@host> exit
      % exit
    5. Issue the commit synchronize command and ensure that there are no synchronization errors:
      user@host# commit synchronize
