Classifying Layer 2 frames based on Layer 3 information

The devices support classifying Layer 2 frames based on Layer 3 fields. You can match on DSCP bits in IPv4 packets (classifier type dscp), TOS bits in IPv6 packets (classifier type dscp-ipv6), EXP bits in MPLS frames (classifier type exp), and PCP bits in IEEE 802.1 frames (classifier type ieee-802.1). To do this, define classifiers as normal at the [edit class-of-service classifiers classifier-type classifier-name] hierarchy level and then apply the classifiers to a Layer 2 (family ethernet-switching) interface at the [edit class-of-services interfaces interface-name unit 0] hierarchy level.
