Creating AVC QoS Policy
To create AVC QoS policy, perform these general steps:
1. Create a class map with match protocol filters.
2. Create a policy map.
3. Apply the policy map to the interface.
Creating a Class Map
You need to create a class map before configuring any match protocol filter. The QoS actions such as marking
and policing can be applied to the traffic. The AVC match protocol filters are applied to the wired access
ports. For more information about the protocols that are supported, see http://www.cisco.com/c/en/us/td/docs/
