Re: Output Drops on Interface

If drops would be more pronounced, you would need to look into reducing
burstiness of the traffic.
But as others pointed out - the drops you have there do not look like
something too interesting is happening.

Remember, when you are looking at the counters, always consider the last
time when they were erased.
Do not be afraid to erase counters, but watch out not to clear (reset)
interface itself.

DO: "clear counters [interface x/x]" --- clears counters
DO NOT: "clear interface x/x" --- resets the interface
