Mention a name to the group and click ADD. 3. Expand all | Collapse all AOS 8. 0 or later versions. Each controller in this deployment model supports approximately 50% of its total AP capacity, so if one controller fails, all the APs served by that controller would fail over to the other controller, thereby providing high availability redundancy to all APs in the cluster. In an Instant deployment scenario. There is a limitation, as of today. 0. Controller 1: 172. 2. I think the command is "show lc-cluster vlan-probe status", I had to remove vlan 1 from the configuration to make it a L2 cluster instead of a L3.
