Configuring the RADIUS Connect-Info Attribute on the LNS

You can configure the LNS to generate the RADIUS Connect-Info attribute [77]. Service providers can then use the information in the RADIUS attribute to identify a customer’s service.

On the LNS, the Connect-Info attribute is based on the L2TP connect-speed AVPs received from the LAC. The LNS does not generate the attribute by default. The format of the Connect-Info attribute is as follows, where the TX speed and RX speed are equal to the respective L2TP AVPs:

The TX speed is always included in the attribute when the speed is not zero; however, inclusion of the RX speed depends on the keyword you use with the command.

• Use the l2tp-connect-speed keyword to specify that the RX speed is only included when it is not zero and also is different than the TX speed.
  host1(config)#radius connect-info-format l2tp-connect-speed
• Use the l2tp-connect-speed-rx-when-equal keyword to specify that the RX speed is always included when it is not zero.
  host1(config)#radius connect-info-format l2tp-connect-speed-rx-when-equal
