Chapter 14 Quality of Service (QoS)
IAD User’s Guide
165
Use this screen to enable or disable QoS, and select to have the IAD automatically
assign priority to traffic according to the IEEE 802.1p priority level, IP precedence
and/or packet length. See
Section 14.1 on page 163 for more information.

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 IAD 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 IAD to not use some of the interface’s available
bandwidth.
