Hi Ed,

I dont think I’m going to be too much help but I am interested in following this thread. From your post it sounds like you performed all logical steps to try to troubleshoot it.

A couple things that are interesting. The issue only is experienced on legacy panel views…I assume you’re referring to the Panelview line that runs the old Panelbuilder32 software. The thing that’s interesting is that when you put an unmanaged switch the problem goes away. That would indicate to me a Cisco configuration issue/mismatch somewhere…but why effecting only the old Panelviews???

Interesting problem. Please do update when you find a solution.  Hopefully some of the network gurus here can offer more!
