We currently have in production a 6506_WLC. A few of our AP's alarm with the message: "Interference threshold violation reported by '802.11b/g'..." I noticed the default setting (which we kept) for the Interference Threshold is set to 10. Does anyone have have any recommendations on what it should be set to?
That value is a % meaning that if the interference value on the AP exceeds 10% percent then to alarm. Generally speaking I reccomend you leave it at the default unless you are sure that the interference isn't real. In most cases it's alarming for a valid reason, some of which could be these reasons:
1) you have some source of interference in the area of those AP's that could be negatively impacting your wireless environment, such as a microwave, wireless video camera, etc.;
2) Your AP density is too high or the AP transmit power is too high generating to much co-channel interference.
3) Too few clients to engage the RRM to change channel and power distribution on the access points (ie: check your access points and verify that they all aren't on a single channel)
4) Depending on the firmware version you are running there could be a bug (4.2.171.x and 4.2.181.x) both had some RRM issues that cause wierd things to happen.

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.
