Quality of Service (QoS): Managing Bandwidth More Effectively Using QoS Classifiers To Configure Quality of Service for Outbound Traffic 1. Identify the IP address to use as a classifier for assigning a DSCP policy. 2. Determine the DSCP policy for packets carrying the selected IP address: a. Determine the DSCP you want to assign to the selected packets. (This codepoint will be used to overwrite 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 dscp-map to configure the priority to the codepoint you selected in step 2a. (For details, refer to "Differentiated Services Codepoint (DSCP) Mapping" on page 5-51.) 4. Configure the switch to assign the DSCP policy to packets with the specified IP address. Syntax: qos device-priority < ip-address > dscp < codepoint > Assigns a DSCP policy to packets carrying the specified IP address, and overwrites the DSCP in these packets with the assigned < codepoint > value. This policy includes an 802.1p priority and determines the packet's queue in the outbound port to which it is sent. 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) no qos device-priority < ip-address > Deletes the specified IP address as a QoS classifier. show qos device-priority Displays a listing of all QoS Device Priority classifiers currently in the running-config file. For example, suppose you wanted to assign these DSCP policies to the packets identified by the indicated IP addresses: IP Address 10.28.31.1 10.28.31.130 10.28.31.100 10.28.31.101 DSCP Policies DSCP Priority 15 7 16 5 17 1 17 1 Assign the DSCP policies to the selected device IP addresses and display the result. 5-25
