Cisco Ethernet Output Errors


we have intermittent connection problem for our citrix application. And I can see the reason for that is due to the large number of output errors in my ethernet interface.

Can anyone tell me the reason or possible improvement for me the reduce the number of that.

Please see below for the result of show interface

Re: Cisco Ethernet Output Errors


output erors: Number of times that the receiver hardware was unable to hand received data to a hardware buffer because the input rate exceeded the receiver's ability to handle the data.

but you also have collisions. Are they increaesing? If they are, it may be physical problem.
