This is interesting, we are running 5.1.151.0 code on our WiSMs. Is this a known bug for different versions of code? John
>>> Lee Weers <[email protected]> 5/15/2009 12:21 PM >>> Are you running controller code or WISM? If controller code what version of code are you running? We didn’t see the problem with 5.0.63, but when we upgraded to 5.2.157 we began to see this. The attacking mac was another cisco ap in the system. We have upgraded to 5.2.178 and this fixed the problem. We also tried downgrading to 5.1.??? and that didn’t work.

We continue to see a high number of "DeAuthntication Floods" and other IDS signatures being triggered on the wireless system. We are curious to know what others are doing to mitigate these types of attacks? What tools and techniques are being used? Thanks, John V.
