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 Device 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
Upstream
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 1000 kbps if your Internet connection has an
upstream transmission speed of 1 Mbps.
Setting this number higher than the interface’s actual transmission speed will stop lower
priority traffic from being sent if higher priority traffic uses all of the actual bandwidth.
If you set this number lower than the interface’s actual transmission speed, the Device will
not use some of the interface’s available bandwidth.
Leave this field blank to have the Device set this value automatically.

These fields are ignored if upstream traffic matches a class you configured in the Class
Setup screen.
If you select Ethernet Priority, IP Precedence or Packet Length and traffic does not
match a class configured in the Class Setup screen, the Device assigns priority to
unmatched traffic based on the IEEE 802.1p priority level, IP precedence or packet length.
