I've just installed WCS for the first time and have been configuring the email alerts/alarms. I left the default settings of Critical alerts only but find I am getting spammed.
Now, I want to be alerted when an AP goes offline, but I've found that quite a few of the AP's seem to momentarily loose connectivity on one if not both radio interfaces - and then immediately come back up.
This results in 2 email alerts almost simultaneously - one telling me the AP interface has shut down and disassociated from the controller, and then immediately after another email telling me the previous message has been cleared and the AP has re-associated with the controller. It doesn't appear to be specific AP's but random ones throughout the day.
So 2 questions:
1 - Is this normal behavior for access points and if not, what could be causing it?
2 - Is there any way to set a threshold on the length of time an AP is down before receiving an email alert from WCS?
I suppose you also see the alerts on the wlc. Look at your Wireless tab on your wlc and look toward the bottom of the list. When an ap joins the wlc it shows up on the bottom. Now click on that ap and see the ap uptime and the ap controller up time. If it looks like it rebooted, console into the ap and do a show version and see what was the cause of the reboot.
did you find any solution? I have a similar problem. The problem is that the APs are working correctly and the WLC has no Alarms from the APs but in the WCS I get alarm "AP 'ap-test1' disassociated from Controller" for 2 APs.
I have no idea why because it seems that all APs are working ok.
is there a directly communication between the WCS and AP? because the Controller says it all right.
1st part was that my WiSMs were not set up...the 1st Octet of the Service Port must be different than Manager and AP Manager interfaces. It is actually in a doc -- it ignores the subnet masks!
After I changed that (requires WLC reboot) my messages went down quite a bit. But there is a 2nd part ... not sure if it affects 1131s. I was told that there is a bug in the Marvell chipset. They have a fix in beta and it is going through regression testing. Hopefully out in next release by end of May. So my case is in "Release Pending" status waiting for the fix to be released.

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.
It is a living doc, so check back for changes every so often

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.
