Chapter 4 Attaching Service Policies
Attaching Virtual Access Interface QoS Service Policies
Example 4-19 shows how to use a virtual template interface to apply a QoS policy to PPPoE sessions.
The example configuration shows how to create a virtual template interface, apply the virtual template
to a BBA group, and apply the BBA group to an interface or subinterface. The QoS policy named policy1
is applied to the virtual template interface named Virtual-Template1; Virtual-Template1 is applied to the
BBA group named VPN_1; and VPN_1 is applied to the ATM interface 5/0, which is configured for
aalsnap encapsulation. The QoS policy named voice1 is applied to the virtual template interface named
Virtual-Template2; Virtual-Template2 is applied to the BBA group named VPN_2; and VPN_2 is applied
to the FastEthernet subinterface 3/0/0.33, which is configured as a VLAN subinterface.
