Preface
This guide contains instructions on how to use the AT-S84 management
software to manage and monitor the AT-9000/24 Gigabit Ethernet switch.
The AT-S84 management software has three management interfaces:
menus, web browser, and CLI. You access the menus and CLI interfaces
through the console port on the switch or through Telnet, and the web
browser interface from any management workstation on your network that
has a web browser application. For background information on the
management interfaces, refer to Chapter 1, “Overview” on page 17.
This preface contains the following sections:
“Where to Find Web-based Guides” on page 14

Chapter 1
Overview
This chapter provides an overview of the AT-S84 management software
for the AT-9000/24 Gigabit Ethernet switch. This chapter describes the
different methods for accessing the software and the management access
levels. This chapter contains the following sections:
“Management Overview” on page 18
“Local Connection” on page 19
“Remote Connection” on page 20
“Management Access Level” on page 21

Chapter 1: Overview
Management Overview
The AT-S84 management software allows you to view and adjust the
operating parameters of the AT-9000/24 Gigabit Ethernet switch. Here are
a few examples of the functions that you can perform with the
management software:
Enable and disable ports
Configure a port’s speed and duplex mode
Create port trunks
Configure a port mirror
Configure Quality of Service (QoS)
Create and tagged virtual LANs
Configure 802.1x network access control
The AT-S84 management software is preinstalled on the switch with
default settings for all of the switch’s operating parameters. You do not
have to manage the switch if the default settings are adequate for your
network. Instead, you can use the device as an unmanaged switch by
connecting it to your network, as explained in the hardware installation
guide, and powering on the unit.
Note
The default settings for the management software are listed in
Appendix A, “AT-S84 Default Settings” on page 319.
To actively manage the switch and adjust its operating parameters, you
must connect to an AT-9000/24 Gigabit Ethernet switch and access the
switch’s AT-S84 management software. There are two ways to connect to
the switch:
Locally
Remotely
Depending upon the method you choose, specific AT-S84 management
software interfaces are available. When you have a local connection, you
can use the menus (described in Section I of this guide) or the command
line interface (CLI) (described in Section III). With a remote connection
you can use the menus, CLI, and web browser interfaces, or a third-party
network management application. (The web browser interface is
described in Section II).
The following sections in this chapter briefly describe each type of
management session.
18
Local Connection
AT-S81 Management Software User’s Guide
To establish a local connection with a switch, you connect a terminal or a
PC with a terminal emulator program to the terminal port on the front of the
switch using the management cable included with the unit. This type of
connection 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.
Note
For instructions on how to start a local management session, refer to
“Starting a Local Management Session” on page 26.
With a local connection, you can manage the switch using the menus or
CLI.
A switch does not need an Internet Protocol (IP) address for you to
manage it locally. You can start a local management session on a switch
at any time. It does not interfere with the forwarding of network packets by
the device.
19
Chapter 1: Overview
Remote Connection
You can use any management station on your network that has the Telnet
application, an SNMP manager, or as web browser to manage an
AT-9000/24 Gigabit Ethernet switch. These are referred to as remote
connections.
In order for you to manage a switch using a remote connection, the switch
must have an IP address and subnet mask. To manually assign an IP
address, refer to “Configuring the IP Address, Subnet Mask, and Gateway
Address” on page 32. To configure the switch to obtain its IP configuration
from a DHCP server, refer to “Enabling and Disabling the DHCP Client” on
page 35. The initial assignment of an IP address must be made through a
local management session.
For instructions on how to start a remote management session to use the
web browser interface, refer to “Establishing a Remote Connection to Use
the Web Browser Interface” on page 200.
Using an SNMP
Network
Management
Application
You can use the Simple Network Management Protocol (SNMP) to run a
network management application such as AT-View to manage the switch
through a remote connection. A familiarity with how to use management
information base (MIB) objects is necessary for this type of management.
The AT-S84 management software supports the following MIBs:
SNMP MIB-II (RFC 1213)
Bridge MIB (RFC 1493)
Remote Network MIB (RFC 1757)
Allied Telesyn managed switch MIB
You must download the Allied Telesyn managed switch MIB
(atiswitch.mib) file from the Allied Telesyn web site and compile the files
with your SNMP application. For compilation instructions, refer to your
third-party application’s documentation. Refer to Chapter 4, “SNMP” on
page 59 for information about how to configure SNMP on the switch.
20
Management Access Level
The AT-S84 management software has one level of management access:
manager. When you log in as a manager, you can view and configure all of
a switch’s operating parameters. You log in as a manager by entering the
appropriate username and password when you start an AT-S84
management session. The default username and password are both
“manager”.

Getting Started with the Menus Interface
This chapter provides information and instructions on how to access the
menus interface of the AT-S84 management software by starting a local
management session. This chapter contains the following sections:
“Starting a Local Management Session” on page 26
“Using the Menus Interface” on page 28
“Quitting from a Local Management Session” on page 29
Section I: Using the Menus Interface 25
Chapter 2: Getting Started with the Menus Interface
Starting a Local Management Session
You establish a local management session with the AT-9000/24 Gigabit
Ethernet switch by connecting a terminal or personal computer with a
terminal emulation program to the RS-232 console port on the front panel
of the switch.
Note
You do not need to assign an IP address to the switch to manage
the unit from a local management session.
To start a local management session, perform the following procedure:
1. Connect one end of the management cable included with the switch to
the console port on the AT-9000/24 Gigabit Ethernet switch, as shown
in Figure 1.
801
Figure 1. Connecting the Management Cable to the Console Port
2. Connect the other end of the cable to the RS-232 port on a terminal or
PC with a terminal emulator program.
3. Configure the terminal or terminal emulator program as follows:
Baud per second: 9600
Data bits: 8
Stop bits: 1
Flow control: None
Note
These settings are for a DEC VT100 or ANSI terminal, or an
equivalent terminal emulation program. You cannot change this.

28 Section I: Using the Menus Interface
Quitting from a Local Management Session
To quit a local management session, return to the Main Menu and type Q
for Quit. When you are finished managing the switch, make sure to exit
from a management session. Quitting from a local session prevents
unauthorized changes to the switch’s configuration if you leave your
workstation unattended.
Note
A local management session automatically times out if there is no
management activity during a pre-defined length of time referred to
as the timeout period. The timeout feature is intended to protect the
parameter settings on the switch from unauthorized changes should
you leave your management station unattended during a
management session. The default timeout value is 10 minutes. To
change the timeout default value, refer to “Setting the User Interface
Configuration” on page 38.
