Quality of Service | 857

.

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.
