Validation
As per the qos configuration, when L2 traffic with cos value 2 sent to VTEP1 access-if, the packets forwarded to queue 3 and packets in queue 3 are mapped with dscp value 16 while egress out of tunnel. At VTEP2, when packets with dscp value 16 ingress at tunnel, it is forwarded to queue 4 and packets of queue 4 are remarked with cos value 5.
