======Session Policing======
<note>[[en:dpi:dpi_options:opt_shaping:shaping_session|Configuring Session Policing via CLI]]</note>

You can manage Session Policing in the GUI under SSG control → Services → Session Policings.\\
The process of configuring session policing consists of two steps:
  - Creating a service profile and configuring policing within the profile: selecting protocols and assigning them priority (policing class) or speed. 
  - Overlaying a Policing Profile on a subscriber.

=====Creating and customizing the Service Profile=====
Create a profile to which we will then add protocols and configure policies.\\ 
One protocol can be added to different profiles, and one profile can be overlaid on multiple subscribers.

To create a profile, you need to perform the following actions on the corresponding panel:
  - Press the **+** (Add Profile) button.
  - Enter a profile name
  - Save\\ {{:en:dpi:dpi_components:dpiui:user_guide:ssg_control_section:services:session_policing:profile_creation.png?nolink&450|}}
  - Add the necessary protocols to the created profile: click the + (Add Protocol) button on the Protocols panel 
  - Fill in the details of the protocol/protocol group:
    * Select Mode (Protocol or Protocols Group), fill in the name of the protocol or select the name of the group from the drop-down list
    * Prioritize the selected protocol or group. There are two ways to do this: set the priority or rate.\\ Description of parameters:
      * The **Priority** parameter overrides the class with respect to global DSCP markup
      * With the **Inbound rate** and **Outbound rate** parameters, you can set the traffic rate for a particular session
      * The parameters **Burst inbound rate** and **Burst outbound rate** show what the short-term rate interruption equals
  - Save\\ {{:en:dpi:dpi_components:dpiui:user_guide:ssg_control_section:services:session_policing:profile_filling.png?nolink&450|}}

=====Applying Session Policing to a Subscriber=====
Before applying a profile to a subscriber, it is necessary to enable the profile by clicking on the "Start" icon to the left of the profile or above the profile table:

{{:en:dpi:dpi_components:dpiui:user_guide:ssg_control_section:services:session_policing:profile_start.png?nolink&450|}}

From the graphical interface, you can overlay a service profile on a subscriber in two ways: 
  - [[en:dpi:dpi_components:dpiui:user_guide:ssg_control_section:services:session_policing#per_subscriber_on_the_list|Per subscriber on the list]]
  - [[en:dpi:dpi_components:dpiui:user_guide:ssg_control_section:services:session_policing#to_multiple_or_all_subscribers_in_the_list|To a multiple or all subscribers in the list]]

<note important>You can apply session policing to a large list of subscribers at once via the console, the command syntax is described in the section  [[en:dpi:dpi_components:platform:subscriber_management:policing_mng]].</note> 

====Per subscriber on the list====
  - Open the profile editing window
  - Activate service 18 - Session Policings by clicking the checkbox next to it and select the desired profile
  - Save

{{:en:dpi:dpi_components:dpiui:user_guide:ssg_control_section:services:session_policing:enable_service_for_one.png?nolink&550|}}

====To multiple or all subscribers in the list====
  - Check the required subscribers or select the whole list using the checkbox in the table header.
  - Open the service configuration window\\ {{:en:dpi:dpi_components:dpiui:user_guide:ssg_control_section:services:session_policing:enable_service_for_multiple_1.png?nolink&450|}}
  - Activate service 18 - Session Policing by clicking the checkbox next to it and select the desired profile
  - Save\\ {{:en:dpi:dpi_components:dpiui:user_guide:ssg_control_section:services:session_policing:enable_service_for_multiple_2.png?nolink&550|}}

<note warning>In the debugging and testing mode, assigning services to a subscriber can be done in the GUI.\\ 
In industrial operation mode, it is recommended to do this with the help of billing: [[en:dpi:dpi_components:platform:dpi_billing|by the PUSH method]] or [[en:dpi:bras_bng:radius_integration|with Radius]], and use the GUI to __track__ the settings made.</note>
