Command Usage
◆ Each node must be connected to two neighbors on the ring. For convenience,
the ports connected are referred to as east and west ports. Alternatively, the
closest neighbor to the east should be the next node in the ring in a clockwise
direction, and the closest neighbor to the west should be the next node in the
ring in a counter-clockwise direction.
◆ Note that a ring port cannot be configured as a member of a spanning tree, a
dynamic trunk, or a static trunk.
