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.
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

This is the start of a display filter cross reference between Wireshark and OmniPeek.
The 1st installment is a table of advanced filters. More filters will be added as time allows.

I have created a Powershell script to automatically add a Wireless Guest User on Cisco WLCs. (tested on 2500 Series)
The script should be completely self explanatory.
