Preface
This guide contains instructions on how to configure an AT-8300 Series
switch or AT-8300 Series stack using the AT-S25 management software.
The Fast Ethernet switches in the AT-8300 Series include the following:
❑ AT-8316F/MT
❑ AT-8316F/VF
❑ AT-8316F/SC
❑ AT-8324
12
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 could access the AT-S25 management software on a switch.
Section II: Local and Telnet Management
The chapters in this section explain how to manage an AT-8300 Series
stack from a local management interface or a Telnet management
interface.
A local management interface is established by connecting a terminal or
PC to the RS-232 Terminal Port on the front panel of the Master switch of
the stack.
A Telnet management interface is established using the Telnet
application protocol. This type of management interface can be
performed from any workstation on your network that has the
application protocol.
AT-S25 Management Software User’s Guide
Section III: Web Browser Management
The chapters in this section explain how to manage a stack using a web
browser, such as Microsoft® Internet Explorer or Netscape® Navigator,
from a workstation on your network.

AT-S25 Management Software User’s Guide
Upgrading AT-S25 Version 1.5.6.2 or Earlier to Version 2.0.2
or Later
This section contains the procedures for upgrading an image file to
AT-S25 Version 2.0.2 or later.
Caution
The configuration file in the AT-S25 Version 1.5.6.2 or earlier version
is not compatible with the AT-S25 Version 2.0.2 or later versions of
code; therefore, the user needs to save the configuration settings
such as the static MAC addresses, VLAN settings, port configuration
settings, etc. before downloading the latest version of code. Once
the latest version of code is downloaded, these settings must be
reconfigured manually.
Note
You cannot perform this procedure from a Telnet or Web Browser
management interface.
Note
The switch will not forward Ethernet traffic during the software
download and initialization process.
Two methods that you could use to download the image file are the
TFTP and XModem methods.
❑ TFTP Method: This method is used to upgrade the software to the
switch modules that are part of a stacked configuration or to the
entire stack at once. This method may be performed from either a
local or a remote host PC.
❑ XModem Method: This method is used to upgrade the software to
an individual switch module of a stack or to a stand-alone switch
module. If the switch module is a member of a stack, the stacking
cable(s) must be disconnected from the module before starting
this procedure. This method may be performed from a local host
PC only.
Note
For faster transfer, the TFTP method is preferable.
For guidelines or background information on how to upgrade the
software using TFTP, refer to TFTP Guidelines on page 18.
17
Preface
TFTP GuidelinesIn the legacy code of AT-S25 Version 1.5.6.2 or an earlier version and
Version 1.5.6.3, the TFTP server software runs on the switch, so the user
has to use the Put command of the TFTP client software on a PC to
download an image file to the switch. However, AT-S25 Version 2.0.2 and
after is designed to use the TFTP client software on the switch. As a
result, the user must run TFTP server on the PC to download the image
file to the switch when Version 2.0.2 or later is the current software. For
further information on software downloads, refer to Chapter 14: File Downloads and Uploads on page 178.
TFTP software is available from various sources and is included in SNMP,
which can be purchased through Allied Telesyn. A command line
version, is included in most UNIX variants, Windows 2000, Windows NT,
and Windows XP. Please consult the documentation or the
manufacturer of the software for instructions on how to use the
software.
Note
This is a two-step method used to upgrade the software to the
switch modules that are part of a stacked configuration or to the
entire stack at once. This method may be performed from either a
local or a remote host PC.
Regardless of the manufacturer, all TFTP client software will need the
following information:
Host - This is the IP address of the switch to which you are
downloading the software.
Binary or ANSI - You will need to specify binary mode (-i) for the
file transfer.
Put - The Put command is used to download a new software
image file to the switch.
Source file - When using the Put command to download software
to the stack, enter the path and filename of the file to be
downloaded onto the switch. The filename must be
“ATS25_V1563.IMG” or “ATS25_V202.IMG”, for example,
depending on the new software image that is being downloaded.
Destination file - When using the Put command to download the
software from a stack, the filename must be “ats25.img”. (No path
should be specified for this file.)
Example:
tftp -i 149.35.1.1 put c:\ats25_v1563.img ats25.img
tftp -i 149.35.1.1 put c:\ats25_v202.img ats25.img

Using TFTP to
Download the
AT-S25 Version
2.0.2 Image File
to the Master
Switch of the
Stack
In a network consisting of several AT-8316F or AT-8324 switches, you
could simplify the upgrade procedure with the two-step process below:
❑ First, download Version 1.5.6.3 image file “ATS25_V1563.IMG” to
the Master switch of the stack.
❑ Secondly, download Version 2.0.2 image file “ATS25_V202.IMG” to
the Master switch of the stack. In turn, the Master switch will
automatically download the new image file to all the Slave
switches.
To download the AT-S25 Version 2.0.2 image file to the Master switch,
the process is as follows:
1. Download the AT-S25 Version 1.5.6.3 image file to the Master switch
via TFTP.
2. Make sure that the source image file you are downloading is for
Version 1.5.6.3 “ATS25_V1563.IMG”.
After Version 1.5.6.3 is downloaded to the Master switch; the
Master switch in turn will download the image file of this version
to all the Slave switches in the stack when it boots up.

the AT-S25
Version 2.0.2
Image File
When it is rebooted, verify that the current software version is
“1.5.6.3”, and that all the Slave switches also booted up correctly.
3. Download the source image file for Version 2.0.2 “ATS25_V202.IMG” to
the stack via TFTP.
4. Allow the stack to reboot automatically.
This section contains the procedure for upgrading a switch module
running Version 1.5.6.2 or an earlier version to Version 2.0.2 from a local
management interface using the XModem protocol. (You could also
load the new software using TFTP, as explain in the previous section.)
Note
This method is used to upgrade the software to an individual switch
module of a stack or to a stand-alone switch module. If the switch
module is a member of a stack, the stacking cable(s) must be
disconnected from the module before starting this procedure. This
method may be performed from a local host PC only.
Note
Hilgraeve HyperTerminal software is used in this XModem
procedure.

Section I
Overview
The chapter in this section provides a brief overview of the AT-S25
management software. It explains some of the functions that you could
perform with the management software and reviews the different
methods for accessing the AT-S25 software on an AT-8316F or an
AT-8324 Fast Ethernet Switch.
25
Chapter 1
Overview
The AT-S25 management software is intended for an AT-8300 Series
stack of AT-8316F and AT-8324 Fast Ethernet Switches. The software is
used to monitor and adjust a stack’s operating parameters. Functions
that you could 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 Spanning Tree Protocol (STP) and
Rapid Spanning Tree Protocol (RSTP)
❑ Configure port security
❑ Configure IGMP Snooping
❑ Configure and View MAC Addresses
❑ Configure Class of Service
❑ File Uploads and Downloads
The AT-S25 management software comes pre-installed on the AT-8300
Series switch with default settings for all operating parameters. If the
default settings are adequate for your network, you could use the switch
or stack as an unmanaged Fast Ethernet switch simply by connecting the
units to your network, as explained in the hardware installation guide,
and powering ON the devices.
26
AT-S25 Management Software User’s Guide
Note
The default settings for the management software can be found in
Appendix A, AT-S25 Default Settings on page 272.
To actively manage an AT-8300 Series stack, such as to change or adjust
the operating parameters, you must access the switch’s AT-S25
management software. The AT-S25 software has a menu interface that
makes it very easy to use.
There are four different ways that you can access the AT-S25
management software. They are briefly described in the following
sections of the this chapter:
❑ Local Management Session on page 28
❑ Telnet Management Session on page 29
❑ Web Browser Management Session on page 30
❑ SNMP Management Session on page 31
27
Section I: Overview
Local Management Session
You establish a local management session with an AT-8300 Series stack
by connecting a terminal or a PC with a terminal emulator program to
the RS-232 Terminal port on the Master switch of the stack, using a
straight-through RS-232 cable. This type of management interface is
referred to as “local” because you must be physically close to the stack,
such as in the wiring closet where the stack is located.
Once the session is started, you will see a menu from which you could
make selections to configure and monitor the stack. You can configure
all of the switches in a stack from a local management session.
Note
For instructions on starting a local management interface, refer to
Starting a Local Management Interface on page 35.
28
Telnet Management Session
Any management workstation on your network that has the Telnet
application protocol can be used to manage an AT-8300 Series stack.
This type of management session is referred to in this guide as a remote
management because you do not have to be in the wiring closet where
the stack is located. You can manage a stack from any workstation on
the network that has the application protocol.
To establish a Telnet management interface with a stack, you must
assign it an IP address. Initially assigning an IP address to a stack is only
possible through a local management session.
Note
For instructions on how to start a Telnet management session, refer
to Starting a Telnet Management Interface on page 38.
A Telnet management session gives you complete access to all of a
stack’s operating parameters. You can perform nearly all the same
functions from a Telnet management session as you can from a local
management session.
AT-S25 Management Software User’s Guide

Section I: Overview
Web Browser Management Session
You can also use a web browser to manage an AT-8300 Series stack. This
too is referred to as remote management because you can manage a
stack 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 Interface on page 190.
