I got a ticket today and it was in regard to the error count on one of the TenG interfaces on one of our ASR9K's. In looking at the interface I noticed quite a few Input Errors on the port. I cleared the counters and monitored. In checking the port again I saw the Input Errors again incrementing. On the smaller Cisco switches you can ususally run the show interface gig 1/1/1 counters error command. With the ASRs you can not. I am wondering if someone could explain what the Input Errors could mean. Media issue? Incorrect Setting? Not sure what I need to be looking at being I have little time on the ASR's at this point. Thanks.
