Catalyst 6800IA interface "overrun"

Mark Ibrahim
Level 1
Level 1

I have a Catalyst 6880X with five FEX's, each FEX is a stack of two.  I am running software version 15.1(2)SY2 and I have noticed overruns on every interface on the FEX's excluding the uplinks.  Has anyone seen this problem?

I also see it to. I'm not sure it is a problem as there have been no complaints, but the overruns are there on one of my devices as you say

Perhaps a Cisco employee can offer insight

I have a TAC case open, it appears to be a cosmetic bug which the DE's are working on now.
