摘要:
A distributed switch may include a plurality of special-purpose processors that control the different functions of the switch. To enable some special services, however, the distributed switch may need one of these processors to perform the role of a master. When a processor is powered on, the processor may publish a corresponding unique ID. Before electing the master, the special-purpose processors may use a discovery process to identify the network topology of the switch and evaluate the published IDs to determine which processor should be the master. If all the processors nominate the same master processor, then that processor is elected as the master and may finish configuring the distributed switch to enable the special services.
