Create a Class Map to match the vlan in the incoming traffic and a Policy Map to set DSCP value of 30 and the desired outgoing
Queue number and apply the same on the incoming access ports. This usecase describes Access to network flow.

service-policy input type qos match_vlan_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_vlan_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 4.
The traffic flowing out of port 1/1/2 will have VLAN 20, dot1p priority 3 and DSCP value of 30 and flowing out of Queue 4.
Use Case 5: QoS Policy to match incoming dot1p and set DSCP and outgoing Queue
Create a Class Map to match the dot1p priority in the incoming traffic and a Policy Map to set DSCP value of 30 and the desired
outgoing Queue number and apply the same on the incoming access ports.

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_dot1p_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 5.
The traffic flowing out of port 1/1/2 will have VLAN 20, dot1p priority 3 and DSCP value of 30 and flowing out of Queue 5.
