We were hitting three bugs that appear resolved in 8.10.142.0. CSCvm17365 CSCvu55303 CSCvu83242
Very few 3700’s left in our deployment. We are mostly 1815’s, 3800’s, and 4800’s with a few buildings moved to 9130’s. We’ve only been running 8.10.142.0 for about a week in production. So far, so good. Prior to moving to it we were experience quite a few reloads of 1815’s and 3800’s. In an early release candidate of 8.10.142.0 we did experience a controller reload of our 8540. This test controller was a standalone controller. I’m not sure if the bug we encountered that caused the reload has been patched or officially identified but we felt more comfortable running in production since production controllers are in HA a pair.

No issues. 8.8 is similar to 8.5 from feature wise, but it will make us easier to upgrade to 8.10 in the future.

We did upgrade from .151 over the summer…so no one has been on campus really due to COVID. Should we be moving off this?

However just within in last couple of months or so we’ve been chasing problems with clients in dorms connecting to 702w (but dorms with 1815w are fine). Clients keep dropping and re-associating; rapid tx errors causing de-associating then coming back in the logs etc... We think something had to have changed on the client side as we’ve had no issues for a long time prior… students bought a bunch of new ax chipsets this semester that don’t like older N radios?, bigsur updates?… haven’t been able to pin it down. Cisco won’t say much more than ditch 702w… but can’t do that on a dime of course. We have been targeting 8.5.151.0 and 8.5.161.0 as an upgrade path to see if it helps. 8.5.161.0 is the recommended TAC release, but I have a somewhat irrational feeling to try 8.5.151.0 first. Your comments about 8.5.151.0 not totally sucking vindicate my feeling! :) - Matt Craig Network Engineer Information and Communication Technologies New Mexico State University On Nov 20, 2020, at 4:30 AM, Lee H Badman <000000db5b77bd95-dmarc-requ...@listserv.educause.edu<mailto:000000db5b77bd95-dmarc-requ...@listserv.educause.edu>> wrote: WARNING: This email originated external to the NMSU email system. Do not click on links or open attachments unless you are sure the content is safe. Knowing that there is no easy answer on questions of Cisco code versions, I’ll throw it out there anyways. We have been on 8.5.151.0 for quite some time now , with mostly good reliability for 3700s and 3800s alike (occasional need to reboot 3700s), We are due to minimally reboot everything, and I’ve been following the various discussions regarding code bugs and specific client issues these past few months. So curious- is there a solid, reliable newer version to consider? We are not in a hurry to get into .11ax yet for a number of reasons. Given the long and problematic history of WLC code, 8.5.151.0 has been as close to “wow, it actually doesn’t totally suck” as we’ve ever been.
