Incoming Direction

The Incoming Direction area displays the following information:

In Labels Used—This value indicates the specific number of labels that are in use at this point in time on this interface in the incoming direction.

In Discards—The number of inbound labeled packets, which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a labeled packet could be to free up buffer space.

Outgoing Direction

The Outgoing Direction area displays the following information:

Out Labels Used—Indicates the number of top-most labels in the outgoing label stacks that are in use at this point in time on this interface.

Out Discards—The number of outbound labeled packets, which were chosen to be discarded even though no errors had been detected to prevent their being transmitted. One possible reason for discarding such a labeled packet could be to free up buffer space.
