I'm trying to deploy a WLC 4400 with several LAP1131 but I have problems: the APs can't join the controller.
Before starting this conversation, I have read the documentation, set DHCP option 60 and 43 with appropiate values, checked that I can ping the WLC from the AP, set the LWAPP manually... but there's no way. The error message is:
LWAPP_CLIENT_EVENT: spamResolveStaticGateway - gateway found
Sent Msg Type : DISCOVERY_REQUEST
Msg Length : 21
Msg SeqNum : 0
LWAPP_CLIENT_EVENT: spamHandleDiscoveryTimer: Could not discover any MWAR
Reading the forums, it seems that 'Could not discover MWAR' means that the AP can't reach the controller but, what else can I do?
WLC4400 version: 4-1-185
LAP1131 version: c1130-rcvk9w8-mx 12.3(11)JX1
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;
Hope this helps!
