We have an environment with Catalyst 4000 switch for access layer and Catalyst 6509 for core with 1Gb bandwidth as the uplink.
Since the new ethernet blades for the 4000 are 10/100/1000 capable, we would like to know if setting the auto for interface is advisable? The PCs are all set to auto and are also 10/100/1000 capable.
Ideally, we would like to keep the ethernet port in auto mode but not have the speed increase beyond 100Mbps.
Any ideas on how to do this without hardcoding the speed?
