Manually performing an active and standby switchover Optional
Ignoring version check of the standby MPU
When the standby MPU starts up, the system checks the versions of the active MPU and standby MPU. If
the versions of the active MPU and standby MPU are not consistent, the standby MPU cannot be started.
To disable the system from checking the version of the standby MPU:
Step Command Remarks
1. Enter system view. system-view N/A
2. Ignore version check of the
standby MPU.
ha slave-ignore-version-check Enabled by default.
Restarting the standby MPU
When the standby MPU fails, or is to be upgraded, you can restart the standby MPU to validate the
newest version or configuration. However, you need to check the consistency of the versions of the active
MPU and standby MPU. If they are not consistent, configure to ignore version check of the standby MPU.
To restart the standby MPU:
Step Command
1. Enter system view. system-view
2. Manually restart the standby MPU. slave restart
NOTE:
When the standby MPU is restarted, the active MPU performs initial synchronization on the standby MPU.
During this process, the system does not respond to your input. When the initial synchronization is
completed, you can execute all the configuration commands on the active MPU and the active MPU and
standby MPU keep a real-time synchronization process, meaning your configuration on the active MPU
will be copied to the standby MPU to ensure the consistency of the current configuration of the active MPU
and standby MPU.
Manually performing an active and standby
switchover
To upgrade the active MPU, restart the active MPU. To avoid service interruption in this case, perform a
manual active and standby switchover to enable the standby MPU to take over the active MPU.
To manually perform an active and standby switchover:
Step Command Remarks
