When using the firewall auto-configuration function for network devices on the switchover destination site, copy the newest configuration from the source site to the firewall of the destination site.
However, after the switchover operation, to restore the switchover destination site to its previous state, backup the configurations of the firewall on the switchover destination site before copying the configurations of the switchover source site. The backed up configurations are used during "4.5 Operation after Failback".
When CB uplink/downlink ports or external switches are set manually on the switchover source site, and if it was not possible to match the settings among sites in advance for reasons such as a validation of the switchover destination site, make the settings the same.
