Sorry, I didn't notice you were using layer 2. Layer 2 uses SNMP to manage the APs. SNMP can not be used across multiple vlans easily from the controller point of view. It is also no longer fully supported by Cisco. Layer 3 is your friend and what allows all of the really cool stuff in lwapp to happen. Fast secure roaming, voice, and video streaming just to name a few. The 2100 series controllers don't even have layer 2 as an option.
Hi Dani,Just a note to explain this behaviour;Q. My 1131 lightweight access point (LAP) does not register with my 4402 Wireless LAN Controller (WLC). What can be the possible reason for this?A. One common reason is that the Lightweight Access Point Protocol (LWAPP) Transport Mode is configured on the WLC. A 4402 WLC can operate in both Layer 2 and Layer 3 LWAPP mode. Whereas, an 1131 LAP can only operate in Layer 3 mode. Layer 2 mode is not supported on the 1131 LAP. So, if the WLC is configured with the LWAPP Transport Mode of Layer 2, then your LAP does not join the WLC. In order to overcome this problem, change the LWAPP Transport Mode of the WLC from Layer 2 to Layer 3.In order to change the LWAPP Transport Mode using the GUI, go to the WLC page and locate the second selection in the main field which is LWAPP Transport Mode. Change this to Layer 3 and reboot the controller. Now, your LAP is able to register with the controller.From this good Q&A doc;http://www.cisco.com/en/US/products/ps6 ... .shtmlHope this helps!Rob
