DT-Ring+

Introduction
DT-Ring+ is used to provide backup between two rings configured with the DT-Ring
protocol. DT-Ring+ determines the ring and port status depending on the ID of the
backup devices to ensure there is redundancy but no loops. Only one backup port is
allowed on one switch and only two backup ports are allowed in one ring. Backup ports
can be set on either master or slave switches.
