Classify Traffic Class maps differentiate traffic so that you can apply separate quality of service policies to each class. For both class maps, Layer 2 and Layer 3, FTOS matches packets against match criteria in the order that you configure them. Create a Layer 3 Class Map A Layer 3 class map differentiates ingress packets based on the DSCP value or IP precedence, and characteristics defined in an IP access control list (ACL). You may specify more than one DSCP and IP precedence value, but only one value must match to trigger a positive match for the class map. 1. To create a match-any class map, use the class-map match-any command or to create a match-all class map, use the class-map match-all command from CONFIGURATION mode (Figure 24-7). 2. After you create a class-map, FTOS places you in CLASS MAP mode. From this mode, specify your match criteria using the match ip command (Figure 24-7). Match-any class maps allow up to five ACLs. Match-all class-maps allow only one ACL. 3. After you specify your match criteria, link the class-map to a queue using the service-queue command from POLICY MAP mode (Figure 24-7). Figure 24-7.
