What to Do Next
Control policies must be applied to a context by using the service-policy type control command.
Forwarding Subscriber Traffic upon Depletion of Quota
By default, ISG drops subscriber packets when a subscriber’s quota has been depleted. This task enables
you to override the default and forward subscriber traffic when the quota-depleted event occurs.
Before you perform this task you should understand the concept described in the “Quota-Depleted
Event” section.
Quota-Depleted Event
A quota-depleted event occurs when a subscriber’s quota is exhausted and ISG has not yet received a
reauthorization response from the billing server. This event can occur in two situations:
• When a prepaid threshold is not configured and the subscriber’s quota is used up.
• When a prepaid threshold is configured but the quota is exhausted before the prepaid server responds
to the reauthorization request that ISG sent when the threshold was met.
Step 3
policy-map type control policy-map-name
Example:
Router(config)# policy-map type control policyA
Creates or modifies a policy map that defines a control
policy.
Step 4
class type control {control-class-name |
always} event credit-exhausted
Example:
Router(config-control-policymap)# class type
control always event credit-exhausted
Specifies a control class and event for which actions may be
configured.
Step 5
action-number service-policy type service name
policy-map-name
Example:
Router(config-control-policymap-class-control)#
1 service-policy type service name
redirect-profile
Applies the specified service policy map or service profile
in which the ISG Layer 4 Redirect feature has been
configured.
Step 6

Example:
Router(config-control-policymap-class-control)#

Exits the current configuration mode and returns to
privileged EXEC mode.
