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. 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.
