The group of devices in a policy segment are it specified in a device list which is a collection of other device lists and/or device interface profiles. The group of common policy components are specified in a policy template. Policy templates contain the condition and action references that are used to generate policies for the policy segment. The condition reference includes a validity period and a traffic profile. The action reference includes at least one of an IPsec action, a DiffServ action or an RSVP action. The device list, connection type, and policy template are combined to generate all of the policies for a policy segment.
