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?
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.
How do access points configured in Local mode deal with WLANs configured with FlexConnect
Local Switching?
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.
Can I do web authentication with Local switching?
Yes, you can have an SSID with web-authentication enabled and drop the traffic locally after
web-authentication. Web-authentication with Local switching works fine.
Can I use my Guest-Portal on the Controller for an SSID, which is handled locally by the H REAP?
If yes, what happens if I lose connectivity to the controller? Do current clients drop immediately?
Yes. Since this WLAN is locally switched, the WLAN is available but no new clients are able to
authenticate as the web page is not available. But, the existing clients are not dropped off.
Can FlexConnect certify PCI compliance?
Yes. FlexConnect solution supports rogue detection to satisfy PCI compliance.
