PDC traffic crashes switch?
A few months ago we had an Allied Telesyn AT-8000s switch installed by contractors, it would seem to reboot itself every minute or so although a connection would sometimes be present in between reboots.
The switch has (allegedly) been sent back to Allied Telesyn and the contractor has told us that we must have a network loop causing the problem. We had the switch brought back today, and after a day of playing with it we have realised that having our Primary Domain Controller on the network causes the reboots, unplug that one server and everything is fine.
The final test configuration was the PDC on a fibre link directly into the switch, no other equipment involved, the switch still resets itself.
Is it possible that some bizarre server traffic could crash / reboot / reset a switch in under a minute, or is the switch faulty?
The contractor is asking me about spanning tree settings on the server, i've never heard of spanning tree settings on anything other than switches.
Any advice would be appreciated.
