Before defining a profile cluster configuration, refer to the following deployment guidelines to ensure the configuration is optimally effective:
A cluster member cannot adopt more APs than its hardware capacity and license provisions allow. This is important when the number of pooled AP and AAP licenses exceeds the aggregated AP and AAP capacity available after a cluster member has failed. A cluster supported profile should be designed to ensure adequate AP and AAP capacity exists to address failure scenarios involving both APs and AAPs.
When clustering is enabled for a profile and a failure occurs amongst one of the cluster members, AP and AAP licenses are persistent in the cluster even during reboots or power outages. If a cluster member failure were to occur, clustering should remain enabled on all remaining cluster members or the pooled member licenses will be deprecated.
