Associating the Hierarchical Policy Map with a Virtual Template
A virtual template is a logical interface whose configuration can specify generic configuration
information for a specific purpose, user-specific configuration information, and router-dependent
information. You configure a virtual template on an interface and apply QoS policy maps to the virtual
template. The virtual template inherits the QoS features specified in the policy map. When the router
establishes sessions on an interface, the router applies the QoS features specified in the virtual template
configuration to the virtual access interfaces (VAIs) created for the sessions, including the QoS features
specified in the policy map attached to the virtual template.
To associate the hierarchical policy map with a virtual template, enter the following commands
beginning in global configuration mode:
Command
Step 1
Router(config)# interface
virtual-template template-number
Step 2
Router(config-if)# service-policy {input
| output} policy-map-name
Step 3
Router(config-if)# exit
The following example shows how to associate a policy map with a virtual template. In this example, the
policy map named Parent is associated with the virtual template named VirtualTemplate1.
Router(config)# interface virtual-template1
Router(config-if)# service-policy output Parent
Router(config-if)# exit
Router(config)#
Applying the Virtual Template to an ATM Subinterface
A broadband aggregation group (bba-group) configured on an ATM interface points to the virtual
template the router uses to apply QoS policies to sessions. When a session arrives on an ATM interface,
the router creates a virtual access interface (VAI) for the session and applies the policies associated with
the virtual template to the sessions.
To apply the virtual template with its associated hierarchical policy to an ATM subinterface, enter the
following commands beginning in global configuration mode:

Purpose
Creates a virtual template and enters interface configuration
mode.
template-number is the number you assign to the virtual template
interface to identify it. Valid values are from 1 to 200.
Note You can configure up to 200 virtual template interfaces on
the router.
Attaches the policy map you specify to the virtual template
interface in the inbound or outbound direction that you specify.
input specifies to apply the policy map to inbound traffic.
output specifies to apply the policy map to outbound traffic.
policy-map-name is the name of a previously configured policy
map.
Exits interface configuration mode.
