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.

Only one RPL owner can be configured on a ring. The owner blocks
traffic on the RPL during Idle state, and unblocks it during Protection
state (that is, when a signal fault is detected on the ring).
The east and west connections to the ring must be specified for all ring
nodes using the ring-port command. When this switch is configured as
the RPL owner, the west ring port is set as being connected to the RPL.
