◆ 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.
◆ If a port channel (static trunk) is specified as a ring port, it can not be
destroyed before it is removed from the domain configuration.
◆ A static trunk will be treated as a signal fault, if it contains no member
ports or all of its member ports are in signal fault.
◆ If a static trunk is configured as a ring port prior to assigning any
member ports, spanning tree will be disabled for the first member port
assigned to the static trunk.
