Synchronizing the Configurations

During normal operation, the startup and running configurations are synchronized by default between the two CPU switch modules. In the event of a switchover, the new active CPU switch module uses the current running configuration. Configurations are synchronized either manually from the CLI using the redundancy manual-synccommand or automatically following configuration changes input from the CLI or from SNMP if automatic synchronization is enabled.

Synchronizing Configurations Manually

To immediately synchronize the configurations used by the two CPU switch modules, use the following privileged EXEC command on the active CPU switch module:

Command	Purpose
redundancy manual-sync {startup-config	Immediately synchronizes the configuration.
running-config both}
