Automatic Synchronization

Use the CLI syntax displayed below to configure synchronization components relating to active-to-standby CSM switchover. In redundant systems, synchronization ensures that the active and standby CSMs have identical operational parameters, including the active configuration, CSM, and IOM images in the event of a failure or reset of the active CSM.

The force-switchover command forces a switchover to the standby CSM card.

To enable automatic synchronization, either the boot-env parameter or the config parameter must be specified. The synchronization occurs when the admin save or bof save commands are executed.

When the boot-env parameter of the synchronize command is specified, the BOF, boot.ldr, config, and image files are automatically synchronized. When the config parameter is specified, only the configuration files are automatically synchronized.

Synchronization also occurs whenever the BOF is modified with persistence on and when an admin>save command is entered with no filename specified.
