Enabling Cluster Redundancy

If you have multiple clusters on the network, you can configure cluster redundancy to enable APs managed by a particular cluster to fail over automatically to another cluster if their parent cluster goes out of service or becomes unavailable.

NOTE
Cluster redundancy is supported only on SZ300 and vSZ-H.

Active and standby cluster require running exactly same model, IP mode, Interface numbers, KSP and with AP patches/firmwares. The Super admin / System admin, username & password must be the same in the active & standby clusters.

Cluster redundancy can only be enabled on system without authorized external DP. Rehome per domain and zone are not supported. After disabling cluster HA on a standby cluster, update factory settings manually. Once an Active cluster is set to factory default, it can only be made an Active cluster again either by restoring the entire cluster or by enabling cluster redundancy again. Once a Standby cluster is set to factory default, it can only be made as a Standby cluster again either by restoring the cluster or by clicking "Sync Now" on active cluster.

User need to manually sync license on Standby Cluster after it has been set as Standby cluster by active cluster.

Before you configure cluster redundancy, take note of the following:
  • Cluster redundancy is disabled by default.
  • Only super administrators have the capability to configure the cluster redundancy settings.

Follow these steps to enable cluster redundancy:
  1. Go to System > Cluster. The Cluster page appears.
  2. Select the cluster, scroll down and click the Configuration tab.
  3. On the right side of the Configuration area, click Configure. The Edit Cluster page appears.
  4. In the Cluster Redundancy area, select the Enable Cluster Redundancy check box.
  5. By default, the Schedule Configuration Sync option, appears Enable.
  6. Select the Sync Time in HH:MM format from the drop-down.
  7. In the Backup Cluster area, click Create. The Standby Cluster form appears.
  8. Enter the following External Network details:

    • Primary Management IP, Port

    • Secondary Management IP, Port. This is optional.

  9. Click OK. You have enabled cluster redundancy.
NOTE
Once the standby cluster IP / port has been configured, the active cluster starts to sync configuration to the standby cluster.
NOTE
You can also edit the Standby Cluster by selecting Configure from the Edit Cluster page.
