This topic describes how to enable or disable the deep packet inspection (DPI) feature and the DPI-based monitoring feature for a Smart Access Gateway (SAG) instance.

Prerequisites

The SAG instance for which you want to manage DPI is associated with an SAG-1000 device.

Background information

The DPI feature allows you to create application-aware quality of service (QoS) policies and access control lists (ACLs) to manage network traffic. In addition, you can view monitoring data of applications. DPI regulates network traffic routes through simple and effective solutions and analyzes traffic distribution.

Enable DPI

  1. Log on to the SAG console.
  2. In the top navigation bar, select the region.
  3. On the Smart Access Gateway page, click the ID of the SAG instance.
  4. On the Basic Info tab, find the Advanced Features section and turn on the DPI switch.
  5. In the Enable DPI message, click OK.

Enable DPI-based monitoring

SAG is integrated with Log Service to provide the DPI-based monitoring feature. You can use this feature to analyze traffic distribution of different applications.
Note You must activate Log Service before you can enable DPI-based monitoring. You are charged when you activate Log Service. For more information about the billing rules of Log Service, see Overview. For more information about Log Service, see What is Log Service?.
  1. Log on to the Smart Access Gateway console.
  2. In the top navigation bar, select the region.
  3. On the Smart Access Gateway page, click the ID of the SAG instance.
  4. On the details page of the SAG instance, choose Monitoring > DPI Statistics on Applications.
    1. In the Enable DPI section of the DPI Statistics on Applications tab, click Enable.
      Note If DPI is already enabled, skip this step.
    2. In the Activate Log Service section, click Activate Now.
      After these features are enabled, the traffic monitoring data of the SAG instance is displayed. For more information, see View traffic monitoring data of applications.

Disable DPI-based monitoring

  1. Log on to the SAG console.
  2. In the top navigation bar, select the region.
  3. On the Smart Access Gateway page, click the ID of the SAG instance.
  4. On the details page of the SAG instance, choose Monitoring > DPI Statistics on Applications.
  5. In the upper-right corner of the DPI Statistics on Applications tab, click Disable DPI-based Monitoring
  6. In the Disable DPI-based Monitoring message, click OK.

Disable DPI

If you disable DPI for an SAG instance, DPI-based monitoring is also disabled. In addition, the application rules of the QoS policies and ACLs that are associated with the SAG instance become invalid.

  1. Log on to the SAG console.
  2. In the top navigation bar, select the region.
  3. On the Smart Access Gateway page, click the ID of the SAG instance.
  4. On the Basic Info tab, find the Advanced Features section and turn on the DPI switch.
