FAQ
Q. If I configure LAPs at a remote location as FlexConnect, can I give those LAPs a primary and secondary controller?
Example: There is a primary controller at site A and a secondary controller at site B. If the controller at site A fails,
the LAP does failover to the controller at site B. If both controllers are unavailable does the LAP fall into FlexConnect
standalone mode?
the LAP does failover to the controller at site B. If both controllers are unavailable does the LAP fall into FlexConnect
standalone mode?
A. Yes. First the LAP fails over to its secondary. All WLANs that are locally switched have no changes, and all that are
centrally switched just have the traffic go to the new controller. And, if the secondary fails, all WLANs that are marked
for local switching (and open/pre-shared key authentication/you are doing AP authenticator) remain up.

Q. How do access points configured in Local mode deal with WLANs configured with FlexConnect Local Switching?
A. Local mode access points treat these WLANs as normal WLANs. Authentication and data traffic are tunneled back to
the WLC. During a WAN link failure this WLAN is completely down and no clients are active on this WLAN until the
connection to the WLC is restored.

Q. Can I do web authentication with Local switching?
A. Yes, you can have an SSID with web-authentication enabled and drop the traffic locally after web-authentication.
