Redundancy Commands
redundancy
Syntax redundancy
Context admin
config
Description
This command enters the context to allow the user to perform redundancy operations.
force-switchover
Syntax force-switchover [now]
Context admin>redundancy
Description This command forces a switchover to the standby CFM card. The primary CFM reloads its software
image and becomes the secondary CFM.
Parameters
now — Forces the switchover to the redundant CFM card immediately.
synchronize
Syntax synchronize {boot-env | config}
Context config>redundancy
Description This command performs a synrchonization 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 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.
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).
