I have a 3620 running 12.0(5)T1 with a NM-1E2W installled in slot 0. When trying to configure the ethernet port to operate at full-duplex the router excepts the command. However, I continue to receive error messages indicating the port is not running at full-duplex, plus the collisions still occur. I can not find a bug report for this problem and I can not find any other documentation where others have has this issue. Can anyone help?
