We've got a Dell PowerConnect 6248 that's about 5 years old that acts as our core switch and hosts vlans. Yesterday we started to have issues with the network crawling to nothing. We rebooted the switch and everything was fine for a few hours. Then same thing again. We ran a constant ping on a couple of switches and noticed it was hitting all of them at the same time. Hopefully you can see this in my screenshot. There also seemed to be an event on the core switch (192.168.64.1) in the ram log. %% Spanning Tree Topology Change: 0, Unit: 1 was the event. Any help to trace this down would be greatly appreciated.
Thanks!
Dusty
