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.
Traffic priority

assigned by
These fields are ignored if upstream traffic matches a class you configured in the 
Class Setup screen.
If you select Ethernet PriorityIP 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.
