About This Guide
How to use this guide
This guide describes how to install and start up the RADIUS daemon, and provides detailed information about how to set up authentication, WAN connections, routing configurations, ATMP tunnels, and accounting records in RADIUS. It assumes that you have already installed the MAX TNT hardware, set up call routing, configured the Ethernet ports, and configured T1 PRI or E1 PRI lines. For details about carrying out these tasks, see the MAX TNT Hardware Installation Guide and the MAX TNT Network Guide.
Note: This manual describes the full set of features for the MAX TNT running software
version 2.0.0. Some features might not be available with older versions or specialty loads of
the software.
What you should know
This guide is intended for the person who will configure and maintain RADIUS and the MAX TNT. To use it effectively, you must have a basic understanding of MAX TNT security and configuration, and be familiar with authentication servers and networking concepts.
While this guide attempts to provide enough conceptual framework to enable an administrator who is not an expert in a particular network technology to configure RADIUS accurately, it does not start from the beginning with any network management topic. Following are the general areas in which it is helpful have some existing knowledge when configuring RADIUS:
- Dial-in LAN connections, such as PPP and MP+
- Connection cost management and accounting
- Modems
- Frame Relay
- NetWare and IPX routing
- IP routing
- DNS
- OSPF routing (if applicable)
- Multicast (if applicable)
- Packet structure and formats (for defining filters)
- Network security
Documentation conventions
This section explains all the special characters and typographical conventions in this manual.
