Re: show frame-relay pvc

DE = Discard eligible.

The reason you see them in and not out is that they are set in the carrier frame-relay equipment.

The high values indicate that the carrier has marked some of your traffic as being eligible to drop (maybe because it was sent over cir) and the fecn and becn indicate congestion.

There appears to be some out drops too. I am guessing this link is not shaped in any way?

You can also set DE yourself locally. If you did, then you would see de packets out. You currently are not setting DE so you’re showing de out as 0.
