I agree that the NICs don't participate in spanning-tree.   Every few seconds the switch is electing a new root.

The event type is STP - Spanning Tree. Do the NIC cards report back to the switch why it dropped?    I want to isolate the issue because if it is a spanning tree loop, then I am crawling under a bunch of desks tracing cables.   ... View more

Is the link dropping due to the device dropping the link or is it due to spanning-tree dropping the link?      ... View more
