Chapter 10 Quality of Service (QoS) 10.5 Class Setup Click Advanced > Quality of Service > QoS Classification to open the following screen. This screen lists the QoS classifiers. A classifier groups upstream traffic into data flows according to specific criteria such as the source address, destination address, source port number, destination port number or incoming interface. For example, you can configure a classifier to select traffic from the same protocol port (such as Telnet) to form a flow. The classifier also assigns a specific QoS queue, DSCP mark, and/or IEEE 802.1p tag. Figure 51 Advanced > Quality of Service > QoS Classification The following table describes the labels in this screen. Table 38 Advanced > Quality of Service > QoS Classification LABEL DESCRIPTION Class Name This is the name of the classifier. MARK These columns are the QoS setting the ZyXEL Device uses for or assigns to the packets of upstream traffic that match this QoS classifier. DSCP Mark This is the DSCP mark the ZyXEL Device assigns to the packets of upstream traffic that match this QoS classifier. Queue ID This is the QoS queue the ZyXEL Device uses for the packets of upstream traffic that match this QoS classifier. 802.1P Mark This is the IEEE 802.1p mark the ZyXEL Device assigns to the packets of upstream traffic that match this QoS classifier. TRAFFIC These columns identify the upstream traffic to which the QoS classifier CLASSIFICATION applies. RULES Lan Port This is the source Ethernet port of the traffic. Protocol This is the type of packets. DSCP This is the DSCP mark. Source Addr./ Mask This is the IP address (and optionally the subnet mask) of the device that sent the traffic. Source Port This is the port number that a device used to send the traffic. P-663HN-51 User's Guide 109
