• Only one backup port is allowed on one switch.
• Only two backup ports are allowed in one ring.
• Backup ports can be set as either master or slave.
• Do not enable DT-Ring+ if there is only one link between two rings.

3.1.3.12 QoS
Quality of Service (QoS) is used to provide different priorities for different traffic on the
ports of the switch.
A queue is provided by the buffering structure on the hardware where each port supports
4 priority queues which are given the ID no of 0, 1, 2 or 3. The queue ID number also
sets the queue priority where 0 is the lowest and 3 the highest.
