Use this screen to enable or disable QoS and have the ZyXEL Device automatically assign
priority to traffic according to the IEEE 802.1p priority level, IP precedence and/or packet
length.

DESCRIPTION
Active QoS
Select the check box to turn on QoS to improve your network performance.
You can give priority to traffic that the ZyXEL 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.

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 1000 kbps if your Internet
connection has an upstream transmission speed of 1 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 ZyXEL Device to not use some of the interface’s available bandwidth.

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

If you select OFF, traffic which does not match a class is mapped to queue two.
