RADIUS Tagging Support
The system supports RADIUS attribute tagging for tunnel attributes. These ―tags‖ organize together multiple attributes
into different groups when multiple LNS nodes are defined in the user profile. Tagging is useful to ensure that the
system groups all the attributes used for a specific server. If attribute tagging is not supported by your specific RADIUS
server, the system implicitly organizes the attributes in the order that they are listed in the access accept packet.

To configure the system to provide L2TP support to subscribers:
Step 1
Configure the ―Local‖ subscriber with L2TP tunnel parameters and the load balancing parameters with action by
applying the example configuration in the Configuring Local Subscriber section.
applying the example configuration in the Configuring Local Subscriber section.
Step 2
Verify your L2TP configuration by following the steps in the Verifying the L2TP Configuration section.
Step 3
Save your configuration as described in Verifying and Saving Your Configuration chapter.
Configuring Local Subscriber
Use the following example to configure the Local subscriber with L2TP tunnel parameters. Optionally you can
configure load balancing between multiple LNS servers:
