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.
