I have switch-A 3524, fa0/9 is connected to switch-B 2924 fa 0/22. We are observing the output utilization on switch-A fa 0/9 is very high(98.94) and at switch-B 2924 fa 0/22 Input utilization is high(99.06) and there is no other port on switch-B with not more than 10% utilization.
3524, fa 0/9 ----> 2954 fa 0/22
FastEthernet0/9 is up, line protocol is up

reliability 255/255, txload 219/255, rxload 14/255
1005 input errors, 1005 CRC, 0 frame, 1134 overrun, 1134 ignored
0 watchdog, 75042 multicast
I appreciate if some one can help me to find what could be the reason.
Those are really old switches so the best way to look at those ports would be to use "sh controllers ethernet-controller fastethernet x/x " to get a good look at all the stats. If you don't have a way to look at the layer 3 info via netflow or other tools then you may have use a packet analyzer and span those ports to get a look at the traffic. To clear the ethernet controller stats it is "clear controllers ethernet-controller " .
