What is etherPortStatsTxPkts256to511Octets?

This counts transmitted frames between 256 and 511 octets in length inclusive, again including bad frames and FCS octets but excluding framing bits. It is another bucket in the port's outbound frame-size histogram. An admin building a traffic profile for capacity planning would look at how this mid-range bucket trends against the smaller and larger size buckets over time.
