I don't think that's correct at all- CDP makes no difference in my findings as to whether APs come up or not.

Badman Network Engineer CWNA, CWSP Information Technology and Services Syracuse University 315 443-3003 >>> Charles Spurgeon <[EMAIL PROTECTED]> 9/21/2006 6:14 PM >>> Todd, Many thanks for your replies to the issue list from Lee Badman. I wanted to ask for more info on your response to point 10, in which you said that you had to disable cdp in order to get lwapp radios to come up. Am I reading that correctly? We're working on a WiSM deployment beginning later this year and we will be converting Cisco 1230 APs to lwapp. Will we have to disable cdp to get the radios to work? Thanks, -Charles Charles E.
