Configuring ISG Network Forwarding Policies
How to Configure ISG Network Policies
3
If a network forwarding policy is not specified in a user profile or service, the ISG session will inherit
the network service from another source. ISG can inherit a network service from the following sources:
• Global
• Interface
• Subinterface
• Virtual template
These configuration sources are listed in order of precedence. For example, a network forwarding policy
that is configured for a virtual template takes precedence over a network forwarding policy that is
configured on an interface.
For each subscriber session, only one instance of a network forwarding policy can be in effect at any
point in time.

Configuring Network Policies for PPP Sessions in Service Policy Maps
Network policies can be configured in user profiles or service profiles on an external AAA server or in
a service policy map on the ISG device. Perform this task to configure a network forwarding policy for
PPP sessions in a service policy map on the ISG device.
Note If a network forwarding policy is not specified in a user profile, service profile, or service policy map, a
subscriber session will inherit the network forwarding policy from another source. See the
“Configuration Sources for Network Policies” section on page 2 for more information.
