Just looking for (hopefully) a quick answer on this. Got a weird situation with a mgt server looking for link status on a 4500 switch and some Disaster Recovery servers which are down except during DR invocation. Our mgt server always shows these ports as 'down' so when it comes time to patch a new server in, these ports get used causing problems during DR.
Does anyone know how to force a port to stay up on the 4500? I've tried the 'no keepalive' trick, but it doesn't have any effect.
