Classify Traffic

Class maps differentiate traffic so that you can apply separate quality of service policies to different types of traffic.
For both class maps, Layer 2 and Layer 3, Dell Networking OS matches packets against match criteria in the order that you configure them.
Creating 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 ACL. You
can also use VLAN IDs and VRF IDs to classify the traffic using layer 3 class-maps.
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.
NOTE: IPv6 and IP-any class maps cannot match on ACLs or VLANs.
