Guest SSID on a dynamic VLAN (AP1230 with IAS) environment

[alig.norbert]

Hi all,

I got the following situation:

- AP 1230 PEAP-WEP-Auth.

- XP (SP2) Client

- IAS-RADIUS

The dynamic vlan assignement/authentication is working (with one SSID). When I configure a second (guest) SSID, there is no longer possible to get connected with one of the dynamic VLAN (authentication with the RADIUS is working, but no access to the VLAN).

I read an old posting that there is an issue with more than one SSID when using dynamic vlan.

(http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=Security%20and%20Network%20Management&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddded31)

The goal is to prvide an SSID for public/guest access and another SSID for dynamic assignement.

Any ideas?

Thank and greets,

norbert

Try upgarding the firmware verison to 12.3(2)JA2 for this multiple dynamic assignment to work.

Are you using MBSSID to broadcast both networks? If so, there is an incompatibility with MBSSID and Dynamic VLAN assignment.

You need to broadcast only one of the SSIDs (via guest-mode). You can then use the information-element ssidl advertisement feature to inform clients of the additional SSIDs, if required:(http://www.cisco.com/en/US/docs/wireless/access_point/12.3_4_JA/command/reference/cr34main.html#wpmkr2681281)
