number of services configured. You can view the number of service sessions currently
active for a subscriber by viewing the Service Sessions field from the output of the
show service-management command.
If you configured a combined IP4 and IPv6 service, the memory usage is the same
as that required for one subscriber service session. The number of subscribers that
are supported by the line modules depends on the number of available resources,
such as external parent groups. If you configure services that are to be used in an
IPv4 or L2TP network, you need not change the previously defined service macros.
However, if a subscriber requires the service macro applied to IPv6 interfaces or
wants to apply a combined policy for both IPv4 and IPv6 interfaces, you must modify
the macro file for the appropriate service interface type.
Configuring RADIUS Accounting for Service Manager
The Service Manager application supports RADIUS accounting and interim accounting
for subscriber service sessions that are activated by the RADIUS login and RADIUS
CoA methods. When RADIUS accounting is enabled, RADIUS generates:
■
An Acct-Start message when a service session is activated
■
An Acct-Stop message when a service session is deactivated
■
Interim-Acct messages
RADIUS accounting messages always include Service Manager time statistics. You
must enable Service Manager volume statistics for a service session.
When you terminate a subscriber session, Service Manager first sends RADIUS
Acct-Stop messages for any active services associated with the subscriber session,
and then sends the Acct-Stop message for the subscriber session.
NOTE: Service Manager statistics collection is a three-part procedure. You must
configure statistics information in the service definition macro file, enable statistics
collection by either RADIUS or the CLI, and also enable statistics collection for the
policy referenced in the service macro using the
statistics enabled keyword in the
command for policy assignment to a profile at the time of attachment of the policy
to an interface. For detailed information about Service Manager statistics, see
“Configuring Service Manager Statistics” on page 680.
To support RADIUS accounting for Service Manager, the RADIUS Acct-Session-ID
attribute [44] has been extended to include a colon-separated identifier, which
uniquely identifies a service for a subscriber. For example:
erx FastEthernet 12/0:0001048580:002478
The Service-Session attribute (VSA 26-83) identifies the name of the service. This
attribute is the value of the Activate-Service or Deactivate-Service attribute (including
parameter values) that was used in the RADIUS Access-Accept message to activate
or deactivate the service session. For example:
tiered(1280000, 5120000)
