Configuring Policy and RADIUS Updates
Overview: Configuring policy and RADIUS updates
Policy Enforcement Manager™ (PEM™) enables you to schedule policy reevaluations and radius updates on the BIG-IP® system in the following two ways:
- You can configure the interval for reevaluation of policies, for a subscriber session, by configuring the re-evaluation interval. The BIG-IP system evaluates changes in the policy for traffic, once the re-evaluation interval is configured.
- The RADIUS traffic contains the subscriber and IP address information that is monitored by the BIG-IP system. If you enable the timeout interval, the BIG-IP system avoids repeated deletion and creation of the subscriber during the configured interval rate.
Configuring PEM options
On the Main tab, click
. The Options screen opens.
In the Policy Options area, specify (in seconds) the Policy Re-evaluation
Interval at which the policy re-evaluation is triggered, to evaluate the
flow policy again.
The re-valuation interval is only for active flows.For example, a subscriber is provisioned over GX which has a policy to allow Netflix with some bandwidth. The subscriber is able to watch a movie using the Netflix service. However, consider that the PCRF installs a policy for this subscriber to block Netflix over the Gx interface. Then, while the subscriber is viewing the content, the Netflix content is blocked for the subscriber after the configured re-evaluation interval.
In the RADIUS Options area, for the Re-Transmit Timeout setting,
select Enabled and specify the time in seconds. If you select
Disabled, each RADIUS message is handled as a new message and
this might lead to deletion and creation of sessions even though the radius massage is a
This is the timeout after which the RADIUS message is considered as a new message, by the BIG-IP system.
In the Quota Management Options area, for the Default Rating
Group setting, select Create to create a new rating
group for quota management.
This takes you to thescreen. Click to go back to options screen.
In the Statistics Options area, for the Analytics Mode setting,
select Enabled to use analytics reporting. Select the external
logging such as HSL endpoint in the External Log Publisher
This generates Application Visibility and Reporting (AVR) PEM reports, in a timely manner through graphs.
