• online removal of the active CSM
Users can manually force the switchover from the active CSM to the standby CSM
by using the admin redundancy force-switchover now CLI command or the
admin reboot active [now] CLI command.
With the 7705 SAR, the admin reboot active [now] CLI command does not cause
both CSMs to reboot.
6.2.1.5 Synchronization
Synchronization between the CSMs includes the following:
• Configuration and boot-env Synchronization
• State Database Synchronization
6.2.1.5.1 Configuration and boot-env Synchronization
Configuration and boot-env synchronization are supported in admin>redundancy>
synchronize and config>redundancy>synchronize contexts.
6.2.1.5.2 State Database Synchronization
If a new standby CSM is inserted into the system, it synchronizes with the active CSM
upon a successful boot process.
If the standby CSM is rebooted, it synchronizes with the active CSM upon a
successful boot process.
When configuration or state changes occur, an incremental synchronization is
conducted from the active CSM to the standby CSM.
If the synchronization fails, the standby CSM does not reboot automatically. The
show redundancy synchronization command displays synchronization output
information.
If the active and standby CSMs are not synchronized for some reason, users can
manually synchronize the standby CSM by rebooting the standby by issuing the
admin reboot standby command.
