Synchronizing the Supervisor Engine Configurations

During normal operation, the startup-config and config-registers configuration are synchronized by
default between the two supervisor engines. In a switchover, the new active supervisor engine uses the
current configuration.
To manually synchronize the configurations used by the two supervisor engines, perform this task on the
active supervisor engine:
Command
Step 1
Router(config)# redundancy
Step 2
Router(config-red)# main-cpu
Step 3
Router(config-r-mc)# auto-sync {startup-config |
config-register | bootvar | standard}
Step 4
Router(config-r-mc)# end
Step 5
Router# copy running-config startup-config
The auto-sync standard command does not synchronize the boot variables.
Note
This example shows how to reenable the default automatic synchronization feature using the auto-sync
standard command to synchronize the startup-config and config-register configuration of the active
supervisor engine with the redundant supervisor engine:
Router(config)# redundancy
Router(config-red)# main-cpu
Router(config-r-mc)# auto-sync standard
Router(config-r-mc)# auto-sync bootvar
Router(config-r-mc)# end
Router# copy running-config startup-config
Note To manually synchronize only individual elements of the standard auto-sync configuration, disable
the default automatic synchronization feature.
This example shows how to disable default automatic synchronization and only allow automatic
synchronization of the config-registers of the active supervisor engine to the redundant supervisor
engine while disallowing synchronization of the startup configuration:
Router(config)# redundancy
Router(config-red)# main-cpu
