Ignoring version check of the standby MPU
When the standby MPU attempts to start up, the system by default examines its software version
against the software version on the active MPU for inconsistency. If the versions of the active MPU and
standby MPU are not consistent, the standby MPU cannot be started.
To disable the system from examining the software version of the standby MPU:
Step

2. Ignore version check of the
standby MPU.

By default, version check of the
standby MPU is enabled.
Restarting the standby MPU
After the standby MPU has restarted, the active MPU will perform initial synchronization on the
standby MPU. During this process, the system does not respond to your input. After the initial
synchronization is completed, you can execute all the configuration commands on the active MPU
and the active MPU and standby MPU will keep a real-time synchronization process. 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.
To restart the standby MPU:
Step
Command
1. Enter system view.

2. Manually restart the standby MPU.

Manually performing an active and standby
switchover
Before you unplug the active MPU to start an active and standby switchover, perform a manual
switchover so that the standby MPU can synchronize latest configurations from the active MPU.
Before a switchover, make sure the LPUs, active MPU, and standby MPU are operating correctly.
