Using The Deactivate-Service Attribute - Juniper JUNOSE 11.1.X - BROADBAND ACCESS CONFIGURATION GUIDE 6-4-2010 Configuration Manual

JUNOSe 11.1.x Broadband Access Configuration Guide
NOTE: The Service-Timeout and Service-Volume attributes use values captured by
the Service Manager statistics feature to determine when a threshold is exceeded.
Therefore, you must configure and enable statistics collection to use these attributes.
See "Configuring Service Manager Statistics" on page 686.
NOTE: Service Manager terminates a session when the output byte count exceeds
the configured service-volume threshold. The output byte count is captured by the
output-stat-clacl string in the classifier list variable that you configure to collect
statistics. See "Configuring Service Manager Statistics" on page 686.
When the output byte count reaches the threshold, RADIUS deactivates the service
session. You must use tags to associate threshold attributes with the Activate-Service
attribute for the service session.

Using the Deactivate-Service Attribute

You can also include the Deactivate-Service attribute in the subscriber's RADIUS
record. The format for this attribute is the same as the format of the Activate-Service
attribute the name of the service, including parameters. The Deactivate-Service

Using RADIUS to Manage Subscriber Service Sessions
Service-Timeout The number of seconds that the service session is active. You
can specify a number in the range 0–16777215. Values greater than 16777215
are recycled, starting from the initial value of 0. For example, if you specify the
value for Service-Timeout VSA as 16777218, this value is equivalent to 2 for this
VSA. A value of 0 indicates that the session never times out. A particular
Service-Timeout VSA can be used by a maximum of 2000 services.
The service-timeout threshold accuracy is within 30 seconds of the specified
value.
Service-Volume The total number of MB of traffic that can use the service
session. You can specify a number in the range 0–16777215 MB. Values greater
than 16777215 are recycled, starting from the initial value of 0. A value of 0
indicates that there is no limit to the amount of traffic for the session. For
example, if you specify the value for Service-Timeout and Service-Volume VSAs
as 16777216 and 16777217, these values are equivalent to 0 and 1 respectively
for these VSAs. A particular Service-Volume VSA can be used by a maximum of
1000 services.
The service-volume threshold accuracy is based on a 10-second period. Service
Manager does not immediately deactivate a service session when the output
byte count reaches the service-volume threshold. Instead, Service Manager checks
the volume in 10-second intervals and deactivates a service session at the end
of the 10-second period in which the output byte count reaches the volume
threshold. For example, if a threshold is reached 4seconds into the 10-second
interval, the session continues for the remaining 6 seconds in the measuring
period and is then terminated. Therefore, the total volume equals the threshold
plus the volume during the additional 6 seconds.
