Duplex mismatch - Switch changes port speed
Posted on 2005-04-22
I have a Cisco 2950 switch. I have a port duplex mismatch between a port on the switch and a server. The NIC in the
server is an Intel Pro/1000 CT Gigabyte card. It has the latest drivers dated 11/22/04. The port on the switch
is set to 100/Full. This NIC doesn't like that setting and will only run, if I set both the port and NIC to auto.
When I set the port on the switch to Auto, it will run for a couple of days, but eventually will set itself back
to 100/full. Has anyone ever heard of this?
