Preface

This guide contains instructions on how to configure an AT-8400 Series Switch using the AT-S60 management software. Within this manual, the AT-8400 Series Switch is often abbreviated to switch.

How This Guide is Organized

This manual is divided into three sections.
Section I: Overview
This section contains just one chapter. It reviews the different ways that you can access the AT-S60 management software on a switch. In addition, it describes how to specify ports.
Section II: Local and Telnet Management
The chapters in this section explain how to manage a switch from a local management session or a Telnet management session.
To establish a local management session, connect a terminal or PC to the RS-232 Terminal Port on the front of the switch.
To establish a Telnet management session, use the Telnet application protocol. This type of management session can be performed from any workstation on your network.

Preface
Section III: Security Features
The chapters in this section describe how to configure the authentication and advanced security features. The authentication features, 802.1x Port Based Access Control as well as TACACS+ and RADIUS protocols appear in both the AT-S60 version 2.0.0 NE and 2.0.0 software. The Encryption Services, Public Key Infrastructure (PKI), Secure Socket Layer (SSL), and Secure Shell (SSH) features only appear in the AT-S60 version 2.0.0 software. The Web Server chapter contains features that appear in both versions of the software as well as features that only appear in the AT-S60 version 2.0.0 software.
Caution
The software described in this documentation contains certain cryptographic functionality and its export is restricted by U.S. law. As of this writing, it has been submitted for review as a “retail encryption item” in accordance with the Export Administration Regulations, 15 C.F.R. Part 730-772, promulgated by the U.S. Department of Commerce, and conditionally may be exported in accordance with the pertinent terms of License Exception ENC (described in 15 C.F.R. Part 740.17). In no case may it be exported to Cuba, Iran, Iraq, Libya, North Korea, Sudan, or Syria. If you wish to transfer this software outside the United States or Canada, please contact your local Allied Telesyn sales representative for current information on this product’s export status.
Section IV: Web Browser Management
The chapters in this section explain how to manage a switch using a web browser, such as Microsoft Internet Explorer or Netscape Navigator, from a workstation on your network.

Section I

Overview

The chapter in Section I provides a brief overview of the AT-S60 management software. It explains the functions that you can perform with the management software and reviews the different methods for accessing the AT-S60 software on an AT-8400 switch.

Overview

AT-S60 Management Software User’s Guide
The AT-S60 management software is intended for the AT-8400 Series switch. The software is used to monitor and adjust a switch’s operating parameters. Functions that you can perform with the software include:
❑ Enable and disable ports
❑ Configure port parameters, such as port speed and duplex mode
❑ Create virtual LANs (VLANs)
❑ Create port trunks and port mirrors
❑ Assign an Internet Protocol (IP) address and subnet mask
❑ Activate and configure the Spanning Tree Protocol (STP)
❑ Configure port security
The AT-S60 management software comes pre-installed on the AT-8401 management card with default settings for all operating parameters. If the default settings are adequate for your network, you can use the switch as an unmanaged switch simply by connecting the unit to your network (as explained in the hardware installation guide) and powering on the device.
Note
The default settings for the management software can be found in Appendix A, AT-S60 Default Settings on page 585.
To actively manage a switch, by changing or adjusting the operating parameters, you must access the switch’s AT-S60 management software. The AT-S60 software has a menu interface that makes it very easy to use and a web interface for managing a switch with a web browser. In addition, you can use a command line interface to manage the switch, as explained in the AT-S60 Management Software Command Line Interface User’s Guide (PN 613-50401-00).
There are four different ways that you can access the management software on an AT-8400 switch. The methods are referred to as management sessions in this guide. They are:
❑ Local Management Session
❑ Telnet Management Session
❑ Web Browser Management Session
❑ SNMP Management Session
Section I: Overview 25
Chapter 1: AT-S60 Overview
The following sections in this chapter briefly describe each type of management session. In addition, the following sections are provided:
❑ Management Access Levels on page 30
❑ Specifying Ports on page 31
❑ Specifying Time and Date on page 32

Local Management Session

To establish a local management session with an AT-8400 switch, connect a terminal (or a PC) with a terminal emulator program to the RS-232 Terminal port on the switch. This type of management session is referred to as local because you must be physically close to the switch, such as in the wiring closet where the switch is located.
Once the session is started, a menu is displayed from which you can make selections to configure and monitor the switch. You can configure all of a switch’s operating parameters from a local management session. The first time you assign an IP address to a switch, you must use a local connection.
Note
For instructions on starting a local management session, refer to Starting a Local Management Session on page 36.
Section I: Overview 26

Telnet Management Session

Any management workstation on your network that has the Telnet application protocol can be used to manage an AT-8400 switch. In this guide, this type of management session is referred to as a remote management session because you do not have to be in the same wiring closet as the switch you are managing. Instead, you can manage the switch from any workstation on the network that has the application protocol.
To establish a remote management session, you need to assign an Internet Protocol (IP) address to a switch. To establish a Telnet management session with a switch on a subnet, there must be at least one AT-8400 switch with an assigned IP address. Only one switch in a subnet needs to have an IP address. Once you have established a Telnet management session, you can use the enhanced stacking feature of the AT-S60 software to access all AT-8400 switches and all Allied Telesyn International switches with Enhanced Stacking capability.
AT-S60 Management Software User’s Guide
Note For further information on enhanced stacking, refer to Enhanced Stacking Overview on page 80.
Note
For instructions on how to start a Telnet management session, refer to Starting a Telnet Management Session on page 40.
A Telnet management session gives you complete access to all of a switch’s operating parameters. You can perform nearly all the same functions from a Telnet management session as you can from a local management session. There are two configuration changes that can only be done with a local connection. The first time you assign an IP address to a switch, you must use a local connection. In addition, you must use a local connection to perform downloads using an xmodem connections.
Section I: Overview 27
Chapter 1: AT-S60 Overview

Web Browser Management Session

You can also use a web browser to manage a switch. Using a web browser management session is also referred to as remote management, just like a Telnet management session. You can manage a switch from any workstation on your network that has a web browser.
Note
For instructions on starting this type of management session, refer to Starting a Web Browser Management Session on page 429.
Section I: Overview 28

SNMP Management Session

Another way to remotely manage the switch is with an SNMP management program. A familiarity with Management Information Base (MIB) objects is necessary for this type of management.
The AT-S60 software supports the following MIBs:
❑ SNMP MIB-II (RFC 1213)
❑ Bridge MIB (RFC 1493)
❑ Interface Group MIB (RFC 2863)
❑ Ethernet MIB (RFC 1643)
❑ Remote Network MIB (RFC 1757)
❑ Allied Telesyn managed switch MIB
AT-S60 Management Software User’s Guide
You must download the Allied Telesyn managed switch MIB files (atiChassisSwitch.mib and atiStackinginfo.mib) from the Allied Telesyn web site and compile the file with your SNMP program. For instructions on how to compile the MIB file with your SNMP program, refer to your SNMP management documentation.
For information about how to configure SNMP communities using a local or Telnet management session, see Chapter 4, SNMP Community
Strings on page 68.
Note
SNMP management can use the enhanced stacking feature through the private MIB (atiStackinginfo.mib). See Chapter 5: Enhanced Stacking on page 79.
