Configuring ISG Policy Templates

Configuring ISG Policy Templates

In Cisco IOS XE Release 3.10S, the Configuring Intelligent Services Gateway (ISG) Policy Templates feature optimizes the provisioning of ISG policies on IPv4 and IPv6 subscriber sessions. It enables support of up to 128,000 IP subscriber sessions with more complex ISG policies at a higher churn rate on the Cisco ASR 1000 Series Aggregation Services Routers.

Restrictions for Configuring ISG Policy Templates

Enabling policy templates in the ISG is not supported for any type of PPP sessions and IP interface sessions.

Information About Configuring ISG Policy Templates

A typical ISG configuration has very few distinct policies and many sessions that use these policies. ISG policy templates take advantage of this to optimize resource consumption and enable support for higher scale. Instead of provisioning an ISG policy with all its individual services and features on each target IP subscriber session, it provisions a template of the policy through the system only once and references the template after that to apply the policy on each target session. Enabling policy templates in the ISG does not impact session SSO.

How to Configure ISG Policy Templates

By default, the ISG policy templates are disabled. The platform subscriber template command enables the ISG policy templates.


Note


The platform subscriber template command does not take effect until the router is reloaded. For example, if this command is entered at the configuration prompt, policy templating remains disabled until the router is reloaded. Similarly, if templating is enabled, the router has to be reloaded after the no subscriber template command is entered to disable ISG policy templating.
