synchronize
Syntax synchronize {boot-env | config}
Context admin>redundancy
config>redundancy
Description This command performs a synchronization of the standby CSM’s images and/or config files
to the active CSM. Either the boot-env or config parameter must be specified.
In the admin>redundancy context, this command performs a manually triggered standby
CSM synchronization.
In the config>redundancy context, this command performs an automatically triggered
standby CSM synchronization.
When the standby CSM takes over operation following a failure or reset of the active CSM, it
is important to ensure that the active and standby CSMs have identical operational
parameters. This includes the saved configuration and CSM images.
The active CSM ensures that the active configuration is maintained on the standby CSM.
However, to ensure smooth operation under all circumstances, runtime images and system
initialization configurations must also be automatically synchronized between the active and
standby CSM.
If synchronization fails, alarms and log messages that indicate the type of error that caused
the failure of the synchronization operation are generated. When the error condition ceases
to exist, the alarm is cleared.
Only files stored on the router are synchronized. If a configuration file or image is stored in a
location other than on a local compact flash, the file is not synchronized (for example, storing
a configuration file on an FTP server).
