Hi
We hafve an estate of ~ 2000 2930 switches/ switch stacks. As prt of our NAC rollout weve been upgrading firmware to latest and greatest as it comes out if there are any authentication related fixes. Our baseline release a few years ago was WC.16.11.13 and everything worked just fine. However, since then we've been. rolling out releases WC.16.11.21,23,25 and now 27 and in all of them we are experiencing issues after a while with being unable to enter commands aftre being logged on. The only solution is to reboot the switch aftwer which everything works for a while. We still have a few WX.16.11.13 switches that have been up for ~150 days with no issues. All switches running same standard config but subequent firmeware releases can't seem to last a week or so before need ing a reboot.
TAC case raised and. installing latest (.27) release for them to look at.
Just wondered if anyone else had seen something similar.
