What's the load on that interface? Are you doing any rate-limiting?

Hi ALL:

A show interface on a GIG port is showing me a large number of output
drops. What is strange is that it is not experiencing any input drops.
Duplex is FULL and speed set to GIG.

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 68368
Queueing strategy: fifo
Output queue :0/40 (size/max)

Appreciate any input.

Cheers,
RAM
