When an SBC SWe cluster is operating in Direct Single configuration mode, the active SBC node saves configuration revisions on the EMS. A new revision number is defined after you explicitly save and activate a set of configuration changes. From the EMS, you can review the list of stored revisions. Each revision is identified by a revision number and a timestamp when the configuration was created. You have the option to revert the cluster configuration back to a prior revision level, when necessary.
Click the Configuration History tab. A list of the stored configuration revisions opens.
Reverting the SBC cluster to a prior configuration revision requires all SBC nodes to reboot which is service impacting.
