What you are seeing is that the channel is clearing of radar traffic that the system was seeing on that specific channel. This piece of the code is related to 802.11h, the standard requiring radar avoidance in the US and Europe. It shouldn't be a worry if it has cleared.</P></BODY></HTML> Sat, 20 Oct 2007 18:32:44 GMT https://community.cisco.com/t5/wireless/error-message-on-wlc/m-p/865202#M10057 dennischolmes 2007-10-20T18:32:44Z Re: Error message on wlc https://community.cisco.com/t5/wireless/error-message-on-wlc/m-p/865203#M10058 <HTML><HEAD></HEAD><BODY><P>If you want to read more on the standard you can go to the IEEE website or google 802.11h</P></BODY></HTML> Sat, 20 Oct 2007 18:34:03 GMT https://community.cisco.com/t5/wireless/error-message-on-wlc/m-p/865203#M10058 dennischolmes 2007-10-20T18:34:03Z
