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.

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.
