I have just upgraded 3 4507R's running Sup V's. I have noticed the CPU utilization is abnormally high. I have 1 switch that has no users on it currently and it's sitting at 17% utilization. The other are at 24% when they are normally at 11% before the upgrade.
The other issue is I now can't use the http interface with these switches that I was able to use before. I get a pop-up box that asks for my username and password and it's not accepting it.
Has anyone else encountered problems with this version?
