Assuming I have all 4 LAN ports connected to PCs. When I remove any one of the connections, the bridge (or precisely eth1) enters the disabled state as normal. However, since all 4 ports share the same eth1 interface, this also takes down the whole thing down and hence disables all other active connections. I have to re-plug the cable back into the port to initiate a learning state -> forward state to bring the connections back or keep at least one connection constantly transmitting packets. However, there is still like 20-30 seconds of disruption before recovery. > If you aren't using STP, just set forwarding delay to zero brctl setfd br0 0 > I was wondering if anyone has experienced this before and appreciate for any solutions!! > Can bridge recognize these ports separately so it doesn't take down everything as a whole? > Only if they are separate interfaces.
