16.3 The QoS General Screen
Use this screen to enable or disable QoS and have the P-660HN-F1A automatically
assign priority to traffic according to the IEEE 802.1p priority level, IP precedence
and/or packet length.
Click Advanced > QoS to open the screen as shown next.

LABEL DESCRIPTION
Active QoS Select the check box to turn on QoS to improve your network
performance.
You can give priority to traffic that the P-660HN-F1A 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.
WAN Managed
Bandwidth Enter the amount of bandwidth for the WAN interface that you want to
allocate using QoS.
The recommendation is to set this speed to match the interface’s actual
transmission speed. For example, set the WAN interface speed to 100000
kbps if your Internet connection has an upstream transmission speed of
100 Mbps.
You can set this number higher than the interface’s actual transmission
speed. This will stop lower priority traffic from being sent if higher priority
traffic uses all of the actual bandwidth.
You can also set this number lower than the interface’s actual
transmission speed. This will cause the P-660HN-F1A to not use some of
the interface’s available bandwidth.
