Yep- but it wasn't the recommended code when changing was convenient to our very large WLAN! We try not to make major code changes when campus is busy, which gives us only a couple of windows a year. And at the time of our last window, the now-buggy code was the recommended.

Lee, We had a similar issue but it was not with the 8540's but instead a pair of WISM2's. Our issue was actually determined to be a bug with a 40 gig line card also in the same 6500 chassis the wism2's were in. We are in the process of turning up a pair of 8540's. What code version is TAC recommending now? We were advised to steer clear of 8.3 for the moment. Curious as to what they are telling you.

Emergency upgrade time... seems like once a semester minimally, we trade one set of bugs for a newer, more exciting set. Grrr.

We're on 8.2.111. From the TAC case notes: We have an 8540 in SSO failover pair config. No changes have been made to the environment in several weeks. With 3,100 APs and 20K clients, we experienced the following condition on multiple secure AND open WLANs that all go to different VLANs: Certain clients- no common type or OS across them- would struggle with select https web page loads while other clients had no problems on same WLANs and same destinations. No problems at all with auth, association, other web sites. And no problems with the target web servers. After hours of troubleshooting, we forced failover to redundant 8540, problem immediately cleared despite all "stateful" failover operations working as they should. Is there a known bug in play here? Just wondering if this occurrence rings any bells for anyone? -Lee Badman ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
