Enables the transmit of Announce messages, which provide properties of this port as a potential grandmaster. Since Announce messages are required for proper operation of the BMCA, this property is ignored when BMCA Enabled? is true. When this property is true, the port transmits Announce messages. This value is the default behavior as specified in the protocol standard. When this property is false, the port does not transmit Announce messages. When this property is false in the grandmaster, slave ports will not receive information about that grandmaster (e.g. properties like Grandmaster Clock Accuracy). Therefore, the false value is useful for in-vehicle applications in which each slave assumes properties for its grandmaster as part of the vehicle's static design.
