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.
- Log onto the EMS.
- Click Network > Cluster Management. The Cluster Management / Manage VNFs window opens listing the SBC clusters on the EMS.
- Click the radio button adjacent to the name of the cluster. The Details tab for the selected cluster opens by default.
Click the Configuration History tab. A list of the stored configuration revisions opens.
Cluster Configuration History
- Click the Restore icon adjacent to a revision to revert the cluster to the configuration that was in place when the selected revision was saved and activated. The active node downloads the selected configuration revision and reboots. If there is a standby node, the active node replicates the configuration to it along with a command to reboot. The active node saves the restored configuration revision back to the EMS and increments the revision number.
Caution
Reverting the SBC cluster to a prior configuration revision requires all SBC nodes to reboot which is service impacting.
