Quality of Service (QoS): Managing Bandwidth More Effectively Using QoS Classifiers To Configure Quality of Service for Outbound Traffic TCP/UDP Port UDP Port 80 (World Wide Web HTTP) 802.1p Priority for TCP 1 802.1p Priority for UDP 1 ProCurve(config)# qos tcp-port 23 priority 7 ProCurve(config)# qos tcp-port 80 priority 2 ProCurve(config)# qos udp-port 23 priority 7 ProCurve(config)# qos udp-port 80 priority 1 ProCurve(config)# qos udp-port range 100 199 priority 3 ProCurve(config)# show qos tcp-udp-port-priority TCP/UDP port based priorities | IP Packet Application | Protocol | Type Port Apply rule | DSCP Priority TCP | IPV4 23 Priority | 7 TCP | IPV4 80 Priority | 2 UDP | IPV4 23 Priority | 7 UDP | IPV4 80 Priority | 1 UDP | IPV4 100-199 Priority | 3 Values in these two columns define the QoS classifiers used to select the packets to prioritize. Indicates that 802.1p priority assignments are in use for packets with 23, 80 or 100-199 as a TCP or UDP port number. Displays the 802.1p priority assignment for packets with the indicated QoS classifiers. Figure 5-5. Configuring 802.1p Priority Assignments on TCP/UDP Ports Assigning a DSCP Policy Based on TCP or UDP Port Number This option assigns a previously configured DSCP policy (codepoint and 802.1p priority) to (IPv4) TCP or UDP packets having the specified port number. The switch does the following: 1. Selects an incoming IP packet if the TCP or UDP port number it carries matches the port number specified in the TCP or UDP classifier (as shown in figure 5-5, above). 2. Overwrites (re-marks) the packet's DSCP with the DSCP configured in the switch for such packets. 3. Assigns the 802.1p priority configured in the switch for the new DSCP. (Refer to "Differentiated Services Codepoint (DSCP) Mapping" on page 5-51.) 4. Forwards the packet through the appropriate outbound port queue. 5-19
