I had a cisco 837 with IOS 12.3(2)XC. The log always has the error message "Dec 9 14:58:45: %CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethernet0
(not full duplex), with switch1 FastEthernet0/1 (full duplex)."
But there is no error message under my router e0 interface. I have to put "no cdp enable" in the E0 iterface to make this error message despair.
Do you think it is a bug?
