ISG Prepaid Billing Support: Example

The following example shows ISG prepaid billing support configured with the following parameters:

• The time threshold is 20 seconds.

• The volume threshold is 1000 bytes.

• When the quota-depleted event occurs, ISG will drop subscriber packets until the billing server

sends another quota.

• When the credit-exhausted event occurs, subscriber packets will be redirected to the server group

“redirect-sg”.

• The prepaid service is called “mp3” and is configured directly on the router in a service policy map.

• The AAA method list that will be used for this service to authenticate subscribers is called

“cp-mlist”. That is the same method list to which the service accounting records will be sent.

• Prepaid authorization, reauthorization and accounting messages will be sent to the AAA method list

called “ap-mlist”.
