I am deploying N+1 HA with 5520 WLC. configuration is done in local mode ( Not flexconnect).
When the shuting down the Primary WLC, wireless client are not able to get an ip address.
Do I need to switch my configuration to flexconnect ?
Ps: The VLAN use by WLAN interfaces is not configured on switches on the remote site off the secondary WLC.
Thanks in advance for your help.
