Syntax synchronize { boot-env | config }
Context config>redundancy
Description This command performs a synchronization of the standby CFM’s images and/or config files to the active
CFM. Either the
boot-env or config parameter must be specified.
In the config>redundancy context, this command performs an automatically triggered standby CFM
synchronization.
When the standby CFM takes over operation following a failure or reset of the active CFM, it is important to
ensure that the active and standby CFMs have identical operational parameters. This includes the saved
configuration, CPM and IOM images.This includes the saved configuration, CPM and IOM images.This
includes the saved configuration and CFM images.
The active CFM ensures that the active configuration is maintained on the standby CFM. However, to ensure
smooth operation under all circumstances, runtime images and system initialization configurations must also
be automatically synchronized between the active and standby CFM.
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.
