This read-only counter reports the highest 1-minute broadcast packet rate, in packets per minute, observed on this port's outbound direction since tracking began or was last cleared. An admin monitors this on trunk or distribution ports to detect broadcast traffic being flooded outbound in unusually high volumes, a sign of a storm elsewhere in the topology being propagated through this port. For example, a high portOutBroadcastPktsPeak on a trunk port while access ports show low broadcast peaks suggests the storm's source is elsewhere in the network and this trunk is simply carrying the flood.
