I got issues. After power outage for long time and UPS was not function. Whole appliance became down included WLCs.
Two of those which hold issues are 126.96.36.199. But another 7.2.x can continue function after power up.
188.8.131.52 made whole campus can not function. We spanned out the traffic and saw much multicast traffic send out. Question is how can those work before power outage. We re quit sure that we have saved the cnfg. And not only 1 WLC got issue but 2. We have 3 of WLC5508.
What is our requirement --- to use Multicast or Unicast.
I totaly agree with Scott and Amjad. This issue should not be related to the Software version used on the WLC.
Go to the Controller tab under the General page and make sure AP Multicast Mode is configured to use
Multicast mode and that a valid group address is configured. The group address is an IPv4 multicast group and is recommended to be in the 239.x.x.x-184.108.40.206 range which is scoped for private multicast applications. Do not use the 224.x.x.x, 239.0.0.x or the 239.128.0.x address ranges for the multicast group address.

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.
