DESCRIPTION
Use this field 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.
Click this to open a summary table showing the QoS settings. See
Section 14.2.1 on page 171
Select the rule's index number from the drop-down list box.
Use this field to enable or disable the rule.
Select an application from the drop-down list box. The Destination Port
Range and Protocol ID fields may change depending on the type of
applications you choose.
Select Enet1 to apply the rule to the Ethernet port or WLAN to apply the
rule to wireless traffic.
Type a destination MAC address here. QoS is then applied to traffic
containing this destination MAC address. Leave it blank to apply the rule
to all MAC addresses.
Enter a destination IP address in dotted decimal notation. QoS is then
applied to traffic containing this destination IP address. A blank
destination IP address means any destination IP address.
Enter a destination subnet mask here.
Either use the default value set by the application you choose, or enter
the port number to which the rule should be applied.
Type a source MAC address here. QoS is then applied to traffic containing
this source MAC address. Leave it blank to apply the rule to all MAC
addresses.
Enter a source IP address in dotted decimal notation. QoS is then applied
to traffic containing this source IP address. A blank source IP address
means any source IP address.
Enter a source subnet mask here.
Enter the port number to which the rule should be applied. 0 means any
source port number. See
services and port numbers.
Select an IP protocol type from the drop-down list box.
Enter the source VLAN ID in this field.
Select IPP/TOS to specify an IP precedence range and type of services.
Select DSCP to specify a DiffServ Code Point (DSCP) range.
Enter a range from 0 to 7 for IP precedence. Zero is the lowest priority
and seven is the highest.
