Configuring the SAE to Write Information About Subscribers to the SSR Database (SRC CLI)

 

When you use an SRC-managed device—for example, an E Series Broadband Services Router as the access node in a PTSP application—you can configure the SAE to write information about dynamic subscribers directly to the SSR database. To do this, you need to configure the SSR writer and specify the mapping between access subscriber session attributes and the SAE plug-in attributes used to identify service node subscriber sessions.

Note

Before you configure the SSR writer, we recommend that you configure the mapping between the SAE plug-in attributes and the SSR subscriber sessions table. The subscriber sessions table schema requires the user IP address and VPN ID; see SSR Database Schema.

Use the following statements to configure the mapping between access subscriber session attributes and the SAE plug-in attributes:

To configure the mapping between access subscriber session attributes and the SAE plug-in attributes:

  1. From configuration mode, access the statement that configures the SSR writer plug-in and specify a name for the plug-in configuration. For example, to configure a plug-in configuration called pc1:

    The name you specify for the configuration plug-in must be specified for the user-tracking-plug-in option under the edit shared network device name virtual-router name statement.

  2. Specify the name of an SAE plug-in attribute to be mapped to the access session attribute, or literal. For example, to specify the login-name SAE plugin attribute:
  3. Specify the name of either an access plug-in attribute or a literal to be mapped to the SAE plug-in attribute.
    • To specify an access plug-in attribute—for example, login-name:

    • To specify a literal—for example, xyz-name:
