-- The counters are all Counter32 instead of Counter64 because of
-- limitations in the pass persist protocol.

		"Total number of packets discarded on egress due to reasons
                reasons other than queue overflow. With IF MIB's ifOutDiscards
                not accounting for certain specific drops, this one accounts
	        for drops seen in the egress pipeline of the system that were
                not because of egress queue overflow drops."
