Hierarchy Level


Specify a dynamic service profile that provides rates for upstream and downstream traffic that the LAC communicates to the LNS. When the Juniper Networks Activate-Service VSA (26-65) is received in the RADIUS Access-Accept message at subscriber login, the VSA is evaluated to determine whether the configured name is also conveyed in the VSA. If it is, the rate values are collected and stored in the session database for the subscriber and then sent in the ICCN message to the LNS. You can either define the rate values as defaults in the service profile or configure them to be passed by RADIUS in VSA 26-65. When they are passed by the VSA, the first value is taken as the receive speed (the upstream rate from the subscriber to the LAC) and the second value is taken as the transmit speed (the downstream rate from the LAC to the subscriber).

The multipliers convert the rates from Kbps to bps, which is required for the AVPs. You can also use the multiplier options to adjust the rates up or down. The adjusted values correspond to the Juniper Networks RADIUS VSAs, Rx-Connect-Speed (26-163) and Tx-Connect-Speed (26-162). These values are stored as such in the session database (SDB). Because the values are available in the SDB before the L2TP connection is negotiated, the LAC includes them in the ICCN message as AVP 38 (Rx connect speed) and AVP 24 (Tx connect speed). The rate values are treated as RADIUS-sourced values and consequently have the highest precedence among multiple sources.



(Optional) Multiplier applied to convert the Rx connect speed value Kbps to bps and optionally adjust the rate up or down.

  • Default: 1000

  • Range: 1 through 2000
