This OID counts how many outbound broadcast packets this 40 Gbps Ethernet (40GbE) interface has transmitted. Watching the outbound broadcast count separately from the inbound one lets an admin tell whether this device itself is the source of excess broadcast traffic rather than merely relaying broadcasts it received. For example, if a 40GbE trunk aggregating several client services shows a high outbound broadcast count with no corresponding inbound broadcast traffic, the local device generating that traffic, rather than an upstream neighbor, would be the first place to check.
