We have a cisco 2821 with an HWIC-1FE ethernet module. We get "status-up, Protocol=down" even if no cable is connected to it. This is different from our 7206, which gives "status-down, Protocol=down" if we disconnect the patch cable from a similar port. Is the link status up/down device dependent, and not "standard" based on cable presence or something?
