This Counter32 counts packets delivered up to a higher sublayer that were addressed to the broadcast address at this sublayer, with discontinuities tied to the interface's counter-discontinuity timestamp. An administrator uses a rapidly rising rate here as an early indicator of a broadcast storm reaching this specific interface. For example, cnt2XIfInBroadcastPkts growing far faster than cnt2XIfInUcastPkts on the same row points to broadcast traffic overwhelming that particular link.
