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
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 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.
Leave this field blank to have the ZyXEL Device set this value
automatically.
Traffic priority
will be
automatically
assigned by 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
ZyXEL Device assigns priority to unmatched traffic based on the IEEE
802.1p priority level, IP precedence or packet length.
