QuestionQ34

Network Resiliency and virtualization

Based on best practices, when an SSID is configured with a primary and secondary gateway cluster and cluster preemption is enabled, what determines whether the APs move to the secondary gateway cluster when all nodes in the primary gateway cluster are down?

Explanation

Each AP independently fails over when all of its tunnels to nodes in the primary gateway cluster are down and at least one node in the secondary cluster is reachable. HPE Aruba Networking documents that AP-to-gateway tunnels exist to both clusters and that this per-AP tunnel reachability condition initiates failover; cluster preemption enables automatic failback after the primary cluster is restored.
