This value reports the breakout configuration type applied to the breakout configuration applied to a port that has been split into several lower-speed sub-ports — for example how a single higher-speed port is being split into multiple lower-speed sub-ports. An administrator planning cabling for high-density switches checks breakoutType on this PortBreakout instance to know how many logical ports a given physical port cage will actually expose once the breakout cable is connected. For example, a breakoutType configured for a four-way split means an operator should expect to see four separate logical ports available where physically there is only one cage.
