Roy: We just turned up an HP GbE2c switch for a blade chassis on a Cisco-only LAN and saw the same thing. The fall from glory was the fact that Cisco does PVST and that the HP uses a single instance of STP for all VLANs. The solution for us was to turn up a mess of STP groups on the HP -- one for each VLAN. That fixed it right up.

Multiple VLANs are involved. When I enabled spanning tree, the whole network seems to seize. I suspect some sort of problem due to the default PVST. I guess I need to switch to MST. Does anyone have any experience in this configuration?
