I'm faced with the same problem, and i'm not sure if it's a driver or bridge problem. I'm using 2 switches, connected on port16. switch1-----switch2-----router \ / \ / server1 Switch1 bridge priority: 4096 Switch2 bridge priority: 5120 Default bridge priority on servers: 65535 If the switches are connected, STP forms just nice, switch1 becomes root. If i disconnect the switch-switch cable, switch1 remains root, the servers see switch1 as root, but switch2 declares itself as root. Guess it's not receiving BPDU packets from the servers. If more than one server is connected to both switches, loop forms, network goes down. If i lower the bridgeprio on server1 to 2048, everybody accepts it as the new root bridge, even switch2. I tested the switches, they play STP nicely in a mixed-vendor environment. Is it possible that the bridge/bnx2 don't propagate BPDUs from switch1 to switch2, while still receiving and transmitting BPDUs?

STP enabled, port cost 4 for both ports, bridge priority 65535. Yesterday i tested the same setup with e1000 cards instead of bnx2 cards, same results. If i lower the bridge priority on server1 to 2048, both switches recognize server1 as the root bridge, and if i connect another server (server2) in the same arrangement, priority 65535, it sees server1 as root.
