redundancy
Syntax redundancy
Context config
Description This command allows the user to perform redundancy operations.
Associated commands include the following in the admin>redundancy context:
force-switchover — Forces a switchover to the standby CPM/CFM card.
now — Switch to standby CPM/CFM.
NOTE: Switching to the standby displays the following message.
WARNING: Configuration and/or Boot options may have changed since the last save.
Are you sure you want to switchover (y/n)?
synchronize — Synchronizes the secondary CPM/CFM.

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.
However, to ensure smooth operation under all circumstances, runtime images and system
initialization configurations 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.
