Quality of Service (QoS): Managing Bandwidth More Effectively Using QoS Classifiers To Configure Quality of Service for Outbound Traffic ProCurve(config)# qos udp-port 23 dscp 15 ProCurve(config)# qos tcp-port 80 dscp 16 ProCurve(config)# qos tcp-port 914 dscp 17 ProCurve(config)# qos udp-port 1001 dscp 17 ProCurve(config)# show qos tcp-udp-port-priority TCP/UDP port based priorities | IP Packet Application | Protocol | Type Port Apply rule | DSCP Priority UDP | IPV4 23 DSCP | 15 7 TCP | IPV4 80 DSCP | 16 5 TCP | IPV4 914 DSCP | 17 1 UDP | IPV4 1001 DSCP | 17 1 Classifier DSCP Policy Figure 5-6. The Completed DSCP Policy Configuration for the Specified UDP/TCP Port Applications The switch will now apply the DSCP policies in figure 5-6 to IPV4 packets received in the switch with the specified UDP/TCP port applications. This means the switch will: ■ Overwrite the original DSCPs in the selected packets with the new DSCPs specified in the above policies. ■ Assign the 802.1p priorities in the above policies to the selected packets. QoS IP-Device Priority QoS Classifier Precedence: 2 The IP device option, which applies only to IPv4 packets, enables you to use up to 256 IP addresses (source or destination) as QoS classifiers. Where a particular device-IP address classifier has the highest precedence in the switch for traffic addressed to or from that device, then traffic received on the switch with that address is marked with the IP address classifier's configured priority level. Different IP device classifiers can have differing priority levels. 5-22
