Introduction
Nortel* Secure Network Access (Nortel SNAS ) is a clientless solution that
provides seamless, secure access to the corporate network from inside
or outside that network. The Nortel SNAS combines multiple hardware
devices and software components to support the following features:
•partitions the network resources into access zones (authentication,
remediation, and full access)
•provides continual device integrity checking using Nortel Health Agent
•supports both dynamic and static IP clients
The Nortel Secure Network Access Switch 4050or 4070 (Nortel SNAS
4050 or 4070) controls operation of the Nortel SNAS.
This user guide covers the process of implementing the Nortel SNAS using
the Nortel SNAS 4050 or 4070 for Nortel Secure Network Access Switch
Software Release 2.0. The document includes the following information:
•overview of the role of the Nortel SNAS 4050 or 4070 in the Nortel
SNAS
•initial setup
•configuring authentication, authorization, and accounting (AAA)
features
•managing system users
•customizing the portal
•upgrading the software
•logging and monitoring
•troubleshooting installation and operation
The document provides instructions for initializing and customizing the
features using the Command Line Interface (CLI). To learn the basic
structure and operation of the Nortel SNAS CLI, refer to “CLI reference”
(page 413). This reference guide provides links to where the function

and syntax of each CLI command are described in the document. For
information on accessing the CLI, see “The Command Line Interface”
(page 377).
BBI is a graphical user interface (GUI) that runs in an online, interactive
mode. BBI allows the management of multiple devices (for example, the
Nortel SNAS) from one application. For information about using BBI to
configure and manage Nortel SNAS, see Nortel Secure Network Access
Switch Configuration — Using the BBI, (NN47230-500).
Before you begin
This guide is intended for network administrators who have the following
background:
•basic knowledge of networks, Ethernet bridging, and IP routing
•familiarity with networking concepts and terminology
•experience with windowing systems or GUIs
•basic knowledge of network topologies
Before using this guide, you must complete the following procedures. For
a new switch:
Step Action
1Install the switch.
For installation instructions, see Nortel Secure Network Access
Switch 4050 Installation Guide , (NN47230-300).
2Connect the switch to the network.
For more information, see “The Command Line Interface” (page
377).
--End--
Ensure that you are running the latest version of Nortel SNAS software.
For information about upgrading the Nortel SNAS, see “Upgrading or
reinstalling the software” (page 367).
