We are running three 7220 controllers in a L2 cluster on 8.5.0.2. I noticed that the client load balancing is all off and almost all clients are on one controller. There are a few hundred clients on the other two controllers, but in general, the majority are on one controller (the cluster leader).
Redundancy Mode On
Active Client Rebalance Threshold = 50%
Standby Client Rebalance Threshold = 75%
Unbalance Threshold = 5%
AP Load Balancing: Enabled
Active AP Rebalance Threshold = 20%
Active AP Unbalance Threshold = 5%
Active AP Rebalance AP Count = 50
Active AP Rebalance Timer = 1 minutes
