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 DSCP value or IP precedence, and
characteristics defined in an IP 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. Create a match-any class map using the command
using the command
2. Once you create a class-map, FTOS places you in CLASS MAP mode. From this mode, specify your
match criteria using the command
up to five ACLs, and match-all class-maps allow only one ACL.
3. After you specify your match criteria, link the class-map to a queue using the command
service-queue
