We have recently seen one of the copper switch ports on a Catalyst 3550-PWR enter a 'unidirectional' state where the output of "sh counters" shows traffic being transmitted by the port, but not any received traffic. (The equipment plugged into the switch was not at fault as it was plugged into another port, and bi-directional traffic flow was observed).
A reload of the switch seems to have cured the problem, but I was wondering whether this has been elsewhere and whether it is indicative of an underlying problem with the switch. The switch is running IOS 12.1(13)EA1c.
