I have a 6509 (distribution, running 12.2(17d)SXB5) and a 6506 (core, running 12.2(17d)SXB1) device that both show Giant counts incrementing. Wanted to know what is an acceptable percentage of Giant packets, and any tips for determining the cause (can pcap captures assist? ie, ethereal?).
I have no known reports of this causing any issues in the network.
