Out-of-sync systems

The master system logs a warning if configuration elements become out of synchronization (out of sync), but does not attempt to correct configuration. You can view the warnings in the log file by issuing the show config-sync status operational command.

If configuration does become out of sync, you can reset the configuration on the standby system by issuing the update config-sync operational command. When this command has successfully completed, the systems are synchronized again.

If the systems become out of sync because of a configuration conflict, the conflict must be addressed before entering the update config-sync command.

The update config-sync command is also useful if the secondary is booted with an out-of-sync configuration. Entering this command on the master system synchronizes the configurations without having to commit a configuration change on the master.

To set up configuration synchronization on the vRouter , use the following work flow.

  1. Identify the master system.
  2. Identify the remote standby system.
  3. Identify the portion of the configuration tree to be synchronized (“include”).
