no shutdown

service-policy input type qos match_dscp_set_dscp_queue
The incoming traffic in port 1/1/1 is an IP traffic with VLAN 10 and dot1p 3 part of the VLAN header and DSCP value of 3 in the
IP header. The Policy map match_dscp_set_dscp_queue is applied on the interface. This results in the following:
The Encapsulated traffic flowing out of Port 1/1/3 has DSCP value of 30 and flowing out of Queue 6. The traffic flowing out of
port 1/1/2 will have DSCP value of 30 and flowing out of Queue 6 and do not have VLAN header since it is an untagged port.
Use Case 8: QoS Policy applied on Untagged access ports part of Virtual Networks
Create a Class Map to match the DSCP value in the incoming traffic and a Policy Map to set a new DSCP value of 30, dot1p
value of 6 and the desired outgoing Queue number 6 and apply the same on the incoming untagged VxLAN access port.

service-policy input type qos untag_match_dscp_set_dot1p
The incoming traffic in port 1/1/2 is an IP traffic DSCP value of 3 in the IP header. The Policy map
untag_match_dscp_set_dot1p is applied on the interface. This results in the following:
The Encapsulated traffic flowing out of Port 1/1/3 has DSCP value of 30 and flowing out of Queue 7.
The traffic flowing out of port 1/1/1 will have VLAN 10, dot1p priority 7 and DSCP value of 30 flowing out of Queue 7.
QoS in VxLAN Network Ports (Traffic from Network ports to Access ports)
Use Case 1: QoS Policy to match incoming DSCP and set new DSCP, dot1p and outgoing Queue
Create a Class Map to match the DSCP value in the incoming traffic on the Network port and a Policy Map to set a new DSCP
value of 30 and the desired outgoing Queue number 6 and apply the same on the network port. The qos-group configured sets
the outgoing dot1p priority in the egress traffic.
