More savy with the 2100 and need to understand how we can "enable" the DPorts (1 or 2) on the 4400 Controller connected to the 2960 Switch, DPorts showing down?
what's the port config on switch ? it should not contain manual speed or duplex config. WLC is made for "auto" and expects the other side to be auto as well.
Did you also check your GBIC/GLC-T ? Maybe they are not inserted correctly or faulty ?
