Counts errors encountered by the L2 relay agent that don't fall into any of the other, more specific drop-reason counters in this MIB. Because every other counter here is tied to a named, specific cause, this catch-all is what an admin checks when total dropped packets (L2Dropped) don't add up to the sum of the named drop reasons -- the remainder shows up here. A firmware bug or an unexpected malformed packet that doesn't match any classified drop reason would still increment this general-errors counter.
