Hi, all, When I plug in a Cisco837 router into the swich, it gives me a warning message: CDP-4-DUPLEX_MISMATCH: duplex mismatch discovered on Ethe rnet0 (not half duplex).
When I do a "sh interface ethernet0", it shows: "Full-duplex,
10Mb/s".The IOS is: 12.3(8). Is there anyway to change it to half duplex?
Thanks.
