Controller redundancy
WebConfiguring VRRP Redundancy. In a n Aruba network, APs are controlled by a controller.The APs tunnel all data to the controller for processing, including encryption/decryption and bridging/forwarding data. Local controller redundancy provides APs with failover to a backup controller if a controller becomes unavailable. Local … End users investigating HA and controller redundancy must ensure that any solution satisfactorily addresses four key areas: 1. deterministic switchover 2. geographically diverse controller installation locations 3. ability to upgrade hardware and firmware revisions without downtime 4. secure native communications. … See more In many cases, conventional wisdom tells us that if one is good then two are better.
