♦UndersizePkts. This statistic counts the number of well-formed packets that were smaller than 64 octets.

♦OversizePkts. This statistic counts the number of well-formed pack- ets that were longer than 1518 octets.

♦Fragments. This statistic counts the number of ill-formed packets less than 64 octets and all events without a start-of-frame delimiter re- gardless of their length.
