Use Case 2: QoS Policy to match incoming vlan and set dot1p priority
Create a Class Map to match the vlan in the incoming traffic and a Policy Map to set dot1p priority of 5 and apply the same on
the incoming access ports.

service-policy input type qos match_vlan_set_dot1p
The incoming traffic in port 1/1/1 has VLAN 10 and dot1p 3. The Policy map match_vlan_set_dot1p is applied on the interface.
This results in the following:
The Encapsulated traffic flowing out of Port 1/1/3 do not have the dot1p priority set as the network ports links are L3 physical
ports.
The traffic flowing out of port 1/1/2 will have VLAN 20 and dot1p priority set as 5.
Use Case 3: QoS Policy to match incoming VLAN and set DSCP
Create a Class Map to match the vlan in the incoming traffic and a Policy Map to set DSCP value of 30 and apply the same on
the incoming access ports.

service-policy input type qos match_vlan_set_dscp
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 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.
The traffic flowing out of port 1/1/2 will have VLAN 20, dot1p priority 3 and DSCP value of 30.
