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.
