Giants on 10GB interface?

We have a 6509 w/ Sup720 IOS and a WS-X6708-10GE. We notice that we receive large amounts of giants on this interface. Is this normal and should we be concerned, any suggestions? Thx!

Re: Giants on 10GB interface?

You may want to look at:


which if I'm reading correctly, since your not seeing any "input errors", you might be okay.

Still, might be worth knowing what's generating the oversized frames.
