Abstract
In one embodiment, systems and method for detecting the intent of a connected optics/cable to operate in either a breakout mode or a non-breakout mode are provided. When a optics/cable is used to connect a port of a spine node to ports of one or more leaf nodes, initially both the spine node and the leaf nodes may automatically configure themselves to operate in breakout mode depending on the optics. Later, the spine node and one or more leaf nodes may exchange speed and optics information using a link layer discovery protocol or another protocol. If the exchanged speed and optics information indicates a mismatch, then the spine node or the leaf node may retain the breakout mode. If the exchanged speed and optic information do not indicate a mismatch, then the spine nodes and the leaf nodes may automatically re-configure themselves in non-breakout mode.
