This read-only Counter64 records the number of broadcast packets transmitted on the port during this bin's period, per its description, the outbound counterpart to the received-broadcast counter covered earlier in this table. A rising trend in this counter across successive bins on an access port can indicate this port is itself flooding broadcast traffic outward, for instance replaying a storm ingested elsewhere in the network, rather than merely receiving one. An engineer trying to locate the origin of a network-wide broadcast storm would check this transmitted-broadcast count across several ports' bins to trace which port first started flooding broadcasts outward.
