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