We ended up shutting down vrrp on each controller, set all controller to 'none' for clustering, removing controllers from the cluster list, deleting the cluster. Then added back the cluster config from square one. Enabled vrrp. Worked perfectly - no lost APs and no errors. -- Jim

How do your RAPs discover the controller, via a DNS record which returns all 4x Public IPs or a DNS Record which returns a 1x Public IP (possibly VRRP?)

We have 4 -- 7220 in a cluster that was previously used to home RAPs. We no longer use this cluster for RAPs but we need to add a 5th controller. When trying to add a new controller get error that maximum of 4 controllers are allowed. The only reference I can find to RAPs in the cluster configuration is the public IP of the controllers. Trying to remove that public IP generated other errors and resulted in losing about 200 APs that had to be rebooted. On each controller we are removing the cluster group-membership. Then deleting each controller from the cluster group. Then adding the controller back without the public IP address. This failed but not clear on the exact cause. Anyone see what we're missing? -- Thanks, Jim
