Does an S series switch with dual MPUs need to synchronize the configuration file between the dual MPUs

1

For an S series modular switch with dual MPUs, you need to run the copy command to synchronize the configuration file from the master MPU to the slave MPU when performing device upgrade or active/standby switchover operations. The slave MPU does not automatically synchronize the configuration file from the master MPU.
