Hi, all

4506 L3 port G5/25-26, there are lot of input errors, 0 output

these two ports are set channel to 3560, 3560 ports are ok, no any errors.

I checked the duplex and speed, all of ports are auto (4506 and 3560)

0 input packets with dribble condition detected

48228810084 packets output, 9429961238952 bytes, 0 underruns

0 output errors, 0 collisions, 0 interface resets


4506 version: 12.2(25)SG

any ideals, Thanks

Drop one port out of the channel and see if the errors persist. If so, add it back and drop the other. Errors like this tend to be cable/fiber related, so eliminate that first.

I am also having problem with this. Ours is not on a layer 3 port however. It's a port on our 4506 which is connected directly to a computer.
