I have an 1031 AP in a remote office which can't join the controller in the HQ. I'm using DNS for WLC discovery and have both the LWAPP + CAPWAP DNS entries configured. AP has static IP + DNS.
Basically the AP resolves the DNS name then connects to the WLC but then the WLC resets the connection.
I've observed the following in the system log:
Here I have the Manager & AP-Manager gateway pointing to the HSRP virtual address on my two 6509 core switches:
*May 27 16:25:44.728: %SIM-3-GW_MISMATCH: sim.c:1018 MAC address of the GW 00:21:56:93:08:00 recieved in the JOIN Request differs from the cached MAC addr 00:00:0c:07:ac:63 of the Gw. Deleting the Gw IP 10.200.1.252 for the AP Mgr & sending
Here' I changed to the gateway to point to the IP on the VLAN SVI interface.
*May 27 16:29:28.338: %SIM-3-GW_MISMATCH: sim.c:1018 MAC address of the GW 00:21:56:93:08:00 recieved in the JOIN Request differs from the cached MAC addr 00:21:a1:23:08:00 of the Gw. Deleting the Gw IP 10.200.1.254 for the AP Mgr & sending
A point to note is that the 00:21 MAC address is the internal L3 router within the 6509.
Network summary:
HQ network is 2 x 6509 running HSRP.
WLC 4404 with LAG into Core 1 switch running 5.2 (can't rember the exact revision)
100Mb WAN link into MPLS cloud, router is also connected to Core 1
Remote office is a DS3 with 3750 switch.

Hi Craig,
I think you are seeing this 5.x (and beyond) restriction
Controller software release 5.0.148.0 or later is not compatible with Cisco Aironet 1000 series access points.

Cheers!

Craig,
Playing back to basics...
1) No FW between your controller and the remote office?
2) Have you tried putting a static address of the controller in the AP?
3) Are you using HREAP by chance?

Can you try to upgrade to 6.X? My doctors have recommended that I stay away from 5.X because it might give me an anaphylactic shock.
