High Availability

cisco.plus · ‎10-20-2011

Hi

Got a High Availability Question.

Location#1 got WLC 5508 and 25 AP + in total AP license of 100

Location#2 got WLC 5508 and 35 AP + in total AP license of 100

There is reachability between two Location.

Both sides will be AD authentication. Each location will have its own Radius Server.

Windows Server at each location is acting as DHCP Server. Access Point is configured with Static IP.

For configuraiton I see Radius authentication on WLC can be configured as primary/failover. For others process I am not clear.

If one of the WLC fails ; how does the High Availability works?

Any input will help

Thanks

If WLC fails, then the 25 AP will join WLC2 and vice versa. Clients connecte to the 25 APs will loose connection for a short duration during the switch to WLC2.
