Appendix A CSG2 Command Reference
ip csg content
• subscriber-ip http-header forwarded-for
• vlan (CSG2 content)
• vrf
You cannot change characteristics for a content while it is in service.
In order to determine the service for a subscriber, the CSG2 first matches a content with the first packet
in a flow, then matches the policy. The CSG2 then uses the content, policy, and the subscriber’s billing
plan to determine the service.
If the content configuration does not match any service listed under a subscriber’s billing plan, the CSG2
considers the service to be either free or postpaid, and the CSG2 forwards the flow and does not try to
authorize the subscriber with the quota server. If BMAs are configured, the CSG2 generates a
per-transaction CDR.
The CSG2 supports overlapping contents, as when one content is a subset of another. If one content
overlaps another, the CSG2 selects the content that best matches the flow. For example, if you configure
Content A with ip any and Content B with ip any tcp 80, the CSG2 matches TCP port 80 flows to
Content B, because ip any tcp 80 is a more precise match than ip any.
The CSG2 does not support duplicate contents. That is, you cannot configure two contents with identical
configurations.
Examples The following example shows how to define the CSG2 content named MOVIES_COMEDY:
ip csg content MOVIES_COMEDY
