priority to traffic according to the IEEE 802.1p priority level, IP precedence and/or
packet length.

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 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.
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.
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 ZyXEL Device will 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
Section 18.5.4 on page 351 for more information.
If you select OFF, traffic which does not match a class is mapped to queue
two.
