LABEL DESCRIPTION
Quality of Service
QoS Use this field to turn on QoS to improve your network performance. 
You can give priority to traffic that the P-660H-T1v3s forwards out 
through the WAN interface. Give high priority to voice and video to make 
them run more smoothly. Similarly, give low priority to many large file 
downloads so that they do not reduce the quality of other applications.
