Re: Output Drops on Interface

"Total Output Drops" is more often software related appose to physical,

Either mis-config, mostly QOS mechanisms or just excess data at a specific
point in time in the output queue.
Any Drops in any QOS method would collectively show as part of the counter
Total Output Drops.

In this case the Interface is not using QOS, (FIFO - Fit In or F off) so it
could just the excess of bursty traffic you seeing,

I'd say nothing to worry about unless that is rapidly increasing.
