Support for matching of DSCP,ECN,VLAN is available under the QOS class-map configuration on Arista switches.

This feature enables support for applying policy maps to Switch Virtual Interfaces (SVI) in the egress direction. A policy map is a Quality of Service (QoS) feature comprising multiple class maps, each with defined match criteria and actions. Class maps evaluate traffic against these criteria, and configured actions are applied to matching traffic. While these policy maps can be applied to interfaces in both input and output directions to match ingress and egress traffic respectively, this feature specifically adds support for applying output policy maps to SVIs.
