A. This error message is seen when a duplex-mismatch exists between the specified port and the device that is connected to it. Set both devices to either auto or hard-coding the duplex on both sides to be the same in order to correct the duplex-mismatch. This resolves the issue. Note: Cisco bug ID CSCsm87892 has been filed regarding this problem, and the bug is moved to Resolved state now. For more information, refer to CSCsm87892 ( registered customers only) .
