RE: Output Drops on Interface

I agree with Dale. If you don't show any input/output errors on the
interface, it is probably just something that got built up over a long time
and a lot of frames. As Dale said, it may seem like a lot, but in the grand
scheme of things is pretty small. What I would do if I was you, would be to
clear the interface counters, and watch it for a few weeks.
