Quality of Service (QoS): Managing Bandwidth More Effectively Using QoS Classifiers To Configure Quality of Service for Outbound Traffic Steps for Creating a DSCP Policy Based on TCP/UDP Port Number Classifiers. This procedure creates a DSCP policy for IPv4 packets carrying the selected UDP or TCP port-number classifier. 1. Identify the TCP or UDP port-number classifier you want to use for assigning a DSCP policy. 2. Determine the DSCP policy for packets carrying the selected TCP or UDP port number. a. Determine the DSCP you want to assign to the selected packets. (This codepoint will be used to overwrite (re-mark) the DSCP carried in packets received from upstream devices.) b. Determine the 802.1p priority you want to assign to the DSCP. 3. Configure the DSCP policy by using qos dscp-map to configure the priority to the codepoint you selected in step 2a. (See "Differentiated Services Codepoint (DSCP) Mapping" on page 5-51 for more information.) 4. Configure the switch to assign the DSCP policy to packets with the specified TCP or UDP port number. Syntax: qos < udp-port | tcp-port > < tcp or udp port number | range > dscp < codepoint > Assigns a DSCP policy to outbound packets having the specified TCP or UDP application port number and overwrites the DSCP in these packets with the assigned value. This policy includes an 802.1p priority and determines the packet's queue in the outbound port to which it is sent. (The must be configured with an 802.1p setting. See step 3 on page 5-20.) If the packet leaves the switch on a tagged port, it carries the 802.1p priority with it to the next downstream device. (Default: No-override) range specifies a range of TCP/UDP ports; see "Operating Notes on Using TCP/UDP Port Ranges" on page 5-18. If you specify a range, the minimum port number must precede the maximum port number in the range. 5-20
