in a dual stack. You can also obtain external parent group statistics for IPv4 and IPv6
services configured independently in a dual stack.
You can retrieve either external parent group statistics or classifier statistics from
policy manager. However, you cannot retrieve both the statistics for a single service
definition. When a combined service is configured, you cannot retrieve classifier
list-based based statistics. In such a scenario, you can only retrieve external parent
group-based statistics from policy manager.
Service interim accounting and accounting based on service deactivation are supported
for IPv6 services. For the combined IPv4 and IPv6 service, the statistics are a sum
of the values in the external parent group and hierarchical policy parameter pair lists
(defined as input-stat-epg, secondary-input-stat-epg, and output-stat-epg in the service
definition macro).
If an interface fails, service-related interim accounting does not calculate the packets
that are transmitted through this failed interface. For statistics reporting, only those
packets that exist for interfaces when the subscriber service session is deactivated
are counted.
Using the CLI to Manage Subscriber Service Sessions
The CLI-based Service Manager creates static subscriber sessions and service sessions.
You can also use CLI commands to immediately deactivate subscriber service sessions.
The CLI-based support is particularly useful for:
■
Testing your service definitions—for example, you might use the CLI commands
to verify that a newly created service definition is correct. When you are satisfied
with the service definition, you can then use RADIUS to activate the service for
your subscribers.
■
Preprovisioning Service Manager services—preprovisioning improves performance
and efficiency by freeing Service Manager from having to repeatedly create and
remove a service that you activate and deactivate for multiple subscribers. See
“Preprovisioning Services” on page 674 for more information about service
preprovisioning.
Using the CLI to Activate Subscriber Service Sessions
A subscriber session represents a specific subscriber—the session consists of the
subscriber’s name, the interface used for the session, and any active services for the
subscriber. A subscriber can have one subscriber session active at any given time.
You create a subscriber’s service session when you assign a service definition to a
subscriber session. Like an AAA-created service, a single subscriber session can have
multiple simultaneous service sessions. You can use one method to create the
subscriber session, and then a different method to activate the subscriber’s service
session. For example, you might use RADIUS to create the AAA subscriber session,
then use the CLI to activate the service session for the subscriber, You can optionally
specify a service session profile that you want to attach to the service session.
You can use the CLI to activate a service session based on subscriber information or
owner information:
