I have an issue with one of my Gig-E interface's on my 7609. I am running 12.2(18)SXF8. The module is a WS-X6408A-GBIC.
Every once in a while my input rate counter will show -93420686.67 and then a few minutes later it jumps to 107875360.83, where then it will finally return to is nornal counter levels after about 5 mins or so?
I just use this Gig-E link as a "bypass" trunk link, in case my primary trunk link fails (using vlan port-priority's), so there really isn't ever that much traffic on it. Usaully about 26Kb or so.
I monitor my interfaces using Cacti (RRD Tool) and lately this has been happening alot. I swapped my GBIC(LH) and that wasn't it. It seems to be some sort of IOS Bug? If anybody has ever seen or experienced this, any help would be greatly appreciated. Thanks!
