Hello
Today I was troubleshooting an ”almost-successful” upgrade on a 4506 sup 6l-e. An almost-successful upgrade from an 15.1 sg6 release to a brand new 15.2.2e7.
Oh my god. The switch started crashing big time every few hours. Show platform crashdump shows dot1x memory allocation problems with a large number of authentications. This caused a 15 minute outage for a whole floor 4 times.
Seriously, one should not apply the latest software without extensive testing.
