Our system:
two 7210 controllers in master, local - OS 6.5.4.7
285 AP 225s
8 AP groups and group profile to direct which group connects to master or local controller
CPPM - OS 6.7.10 - this divides client hardware into OS for bandwidth purposes
3 VLANS - 40, 60 and 80
external Windows box for DHCP
six SSIDs on 3 VLANs
Problem :
VLAN 40 works fine for 2 SSIDS, if I try to add another SSID client connect/disconnect problems arise
I cannot add any SSIDs to VLAN 60
VLAN 80 has 3 SSIDs running fine
