Expansion of Service IDs

The Cisco 10000 router uses service IDs to determine which services a user is subscribed to and how to police the user traffic. A user can be subscribed to a maximum of seven services. However, service translation can result in more than seven network sets. To support the service translation mechanism, the expansion of service IDs enhancement expands the number of service IDs supported from seven to 15.

Restrictions for Expansion of Service IDs

The expansion of service IDs enhancement has the following restrictions:

When service translation is used, the Cisco 10000 router supports a maximum of 15 sets per SSG VRF. If all of the users are configured in the same VRF, the router supports a maximum of 15 network sets per system.

A user can be subscribed to a maximum of seven services and a maximum of 15 network sets.

Configuration Example for Expansion of Service IDs

The following example shows how service IDs are expanded to allow a user to be subscribed to more than seven sets. In this example, the user is subscribed to five services, which is within the seven-services limit. After service translation, the user is subscribed to eight sets, which is within the expanded service IDs limit of 15 network sets.
