Chapter 14 Quality of Service (QoS) The following table describes the labels in this screen. Table 58 Advanced Setup > QoS LABEL DESCRIPTION Quality of Service QoS 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. Summary Click this to open a summary table showing the QoS settings. See Section 14.2.1 on page 175 for more details. Rule Rule Index Select the rule's index number from the drop-down list box. Active Use this field to enable or disable the rule. Application 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. Physical Ports Select Enet1 to apply the rule to the Ethernet port. Destination MAC 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. IP 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. Mask Enter a destination subnet mask here. Port Range Either use the default value set by the application you choose, or enter the port number to which the rule should be applied. Source MAC 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. IP 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. Mask Enter a source subnet mask here. Port Range Enter the port number to which the rule should be applied. 0 means any source port number. See Appendix E on page 307 for some common services and port numbers. Protocol ID Select an IP protocol type from the drop-down list box. Vlan ID Range Enter the source VLAN ID in this field. IPP/DS Field Select IPP/TOS to specify an IP precedence range and type of services. IP Precedence Range 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. 174 P-660HN-TxA User's Guide
