We're using Cisco 8540 on code 8.2.151.0. Last week CPI reported a great number of simultaneous AP disassociations and then reassociation. CPI shows all the events had the exact same timestamp right down to the hundredth second. It was just a single event.
But I can find no event preceding it that would cause such a thing. No preceding controller errors that I can see. At least a hundred APs were on the list. The APs weren't the same type or in the same buildings. I can find no common thing at all about it. No one called in to report any issues. I would think if they really did drop those on an affected AP would have noticed. Only one AP in the building housing IT was on the report, so perhaps not surprising that none of us noticed anything. Has anyone out there seen anything like this? Aside from the unknown cause, is it possible for disassocation and reassociation happened fast enough that users wouldn't see any serious disruption if only doing stateless stuff? I'd have trouble believing the controller would report AP drops that didn't happen. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/discuss.
