Synchronization
Synchronization between the CPMs includes the following:
• Configuration and boot-env Synchronization on page 225
• State Database Synchronization on page 225
Configuration and boot-env Synchronization
Configuration and boot-env synchronization are supported in admin>redundancy> synchronize
and config>redundancy>synchronize
contexts.
State Database Synchronization
If a new standby CPM is inserted into the system, it synchronizes with the active CPM upon a
successful boot process.
If the standby CPM is rebooted, it synchronizes with the active CPM upon a successful boot
process.
When configuration or state changes occur, an incremental synchronization is conducted from the
active CPM to the standby CPM.
If the synchronization fails, the standby does not reboot automatically. The show redundancy
synchronization command displays synchronization output information.
If the active and standby are not synchronized for some reason, users can manually synchronize
the standby CPM by rebooting the standby by issuing the admin reboot standby command on the
active or the standby CPM.
