And- we have a code bug! Who would have thought? Emergency upgrade time... seems like once a semester minimally, we trade one set of bugs for a newer, more exciting set.

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/.
