The AT-S39 manag ement software comes pre-installed o n the switch

with default settings for all operat ing parameters. If the default settings

are adeq uate for your network, you can use the sw itch as an unmanag ed

switch simply by connecting the unit to your network, as explained inthe hardw are insta llat ion g uide, and pow ering ON the device.

NoteThe default settings for the manag ement softw are can be found in

Appendix A,AT-S39 Default Settingson pa ge 312.

To actively manag e a sw itch, such as to chang e or adjust the operating

parameters, you must access the switchs AT-S39 management software.

The AT-S39 softw are has a menu interface that makes it very easy to use,

and a special interface for manag ing a sw itch w ith a web b rowser.

There are four different w ays to access the mana gement softw are on an

AT-8000 Series switch. In this guide, these met hods a re referred to as

management sessions. They are:

Local Manag ement Session

Telnet Manag ement Session

Web Brow ser Management Session

SNMP Management Session

The fo llow ing sect ions in this chapt er briefly describe each type of

manag ement session.

Local Management Session

You ca n establish a local management session with an AT-8000 Series

switch by connecting a terminal or a PC with a terminal emulatorprogram to the RS232 Terminal port on the front pa nel of the switch,

using a st raight -throug h RS-232 cable. This type of management session

is referred to as localbecause you must be physically close to theswitch, such a s in the w iring closet w here the switch is located.

Once the session is started, a menu is displayed and you can make

selections to configure and monitor the switch. You can configure all of

a sw itchs operating parameters from a local mana gement session.

NoteFor instructions on starting a local management session, refer to

Starting a Local Management Sessionon pag e 30.


22/319

Section I: Overview

22

Telnet Management Session

Any manag ement workstat ion on your network tha t ha s the Telnet

applicat ion proto col can be used to manage an AT-8000 Series switch.

This type of management session is referred to in th is guide as a remote

manag ement session because you do not ha ve to be in the wiring closet

where the switch you want to manag e is located. You can mana ge theswitch from any workstat ion on t he netw ork tha t has the application

protocol.

To estab lish a Telnet management session w ith a switch, there must be

at least one AT-8000 Series switch on the subnet that has been assigned

an Internet Protocol (IP) address. Only one sw itch in a subnet needs tohave a n IP address. Once you have estab lished a Telnet manag ement

session w ith the sw itch that ha s an IP address, you can use the enhanced

sta cking fea ture of the AT-S39 softw are to access all other AT-8000

Series switches in the same subnet .

NoteFor further information on enhanced stacking , refer to EnhancedStacking Overviewon pag e 58.

NoteFor instructions on how to start a Telnet management session, refer

to Starting a Telnet Management Sessionon pag e 34.

A Telnet ma nagement session gives you complete access to a ll of a

switchs operat ing pa rameters. You can perform nearly all the same

functions from a Telnet manag ement session as you can from a local

manag ement session.


23/319

AT-S39 Users Guide

23

Web Browser Management Session

You can also use a w eb b rowser to mana ge a switch. This too is referred

to a s remote ma nagement, just like a Telnet ma nagement session. Youcan mana ge a switch from any workstation on your network that has a

web browser.

NoteFor instructions on starting this type of mana gement session, refer

to Starting a Web Browser Management Sessionon page 227.


24/319

Section I: Overview

24

SNMP Management Session

Another way to remotely manag e the switch is with an SNMP

manag ement program. A familiarity w ith Mana gement Information Base(MIB) ob jects is necessary for this type of management.

The AT-S39 software supports the following MIBs:

SNMP MIB-II (RFC 1213)

Bridge MIB (RFC 1493)

Interface Group MIB (RFC 1573)

Ethernet MIB (RFC 1643)

Remote Network MIB (RFC 1757)

Allied Telesyn managed switch MIB

You must do wnload the Allied Telesyn managed switch MIB

(at istackinfo.mib and at iswitch.mib) file from the Allied Telesyn w eb site

and compile the file with your SNMP prog ram. For instructions, refer to

your SNMP mana gement documenta tion.

NoteSNMP manag ement does not utilize the enhanced stacking feature.

Conseq uently, you must assign an IP address to each switch to be

mana ged w ith an SNMP prog ram.

Management Access Levels

There a re two levels of management access on an AT-8000 Series switch:

Mana ger and Operator. When you log in as a Manag er, you can view andconfigure a ll of a switchs operating parameters. When you log in as an

Operator, you can only view the operat ing parameters; you canno t

change any values.

You log in as a ma nag er or an operator by entering the a ppropriat e

password when you sta rt an AT-S39 mana gement session. To log in as a

manag er, type manageras the login and friendas the pa ssword. The

default user name for operator is operatorand the password is also

operator. Both log in and password a re case-sensitive.

Local Management Session

On the front panel of the sw itch is a port lab elled RS232 Terminal Port.

You use this port to estab lish a local mana gement session w ith theswitchs AT-S39 management software.

A local manag ement session is so named because you must be close tothe switch, usually within a few meters, to sta rt this type of manag ement

session. This typically means tha t you must be in the w iring closet w here

the sw itch is located.

A switch does not need an IP address to be mana ged from a local

manag ement session. You can start a local management session a t any

time on any AT-8000 Series switch in your netw ork. Running a local

manag ement session does not interfere with the flow of Ethernet trafficthrough the unit.

Starting a local management session on a switch that has been

configured a s a Master switch of an enhanced stack allow s you tomanag e all the switches in the subnet from the same local manag ement

session. You do not have to start a separate local manag ement session

for each sw itch. This can simplify netw ork management .

Starting a local manag ement session on a switch that is not pa rt of a n

enhanced stack or that is a slave switch in an enhanced stack allow s you

to manag e just tha t switch.

NoteThe switch has an auto-detect fea ture on the serial port that

auoma tically determines the speed of t he local terminal. Activate

this feat ure by pressing the Return or Enter key twice on your

keyboa rd when you initially sta rt the local interface or w ithin five

seconds a fter powering on or resetting the sw itch. The switch

responds by determining the speed of the terminal andautoma tically configuring the speed of the RS232 Terminal Port

accordingly. Otherwise, the switch uses a default ba ud rate of 9600

bits per second (bps). The sw itch maintains the terminal port speed

until the system is aga in powered on o r reset. The rang e of the port s

ba ud ra te is 1200 to 115200 bps.

NoteThe port sett ings are for a DEC VT100 or ANSI termina l, or an

eq uivalent t erminal emulator prog ram.

NoteDuring boot up, the switch displays the follow ing prompt: Pressany key to stop image loading and go to Boot

Prompt. This message is intended for manufacturing purposes

only. (If you inadvertent ly display the boot prompt (= >), type bootand press Return to sta rt the sw itch.)

4. Press the Return key twice.

If prompted for a pa ssword, enter the password for the

mana gement softw are. The default password for manag er accessis friend. The default passw ord for operato r access is operator.

Log ins and pa sswo rds are case-sensitive. For information on the

tw o access levels, refer to Management Access Levelson page25. (For instructions on how to chang e a password, refer to

EnhancedStacking

When you start a local manag ement session on a switch tha t has been

designa ted as the Master switch of an enhanced stack, you can manag e

all the switches in the same subnet from the same manag ement session.

This can save you the t ime and trouble of having to sta rt a separate local

manag ement session each t ime you wa nt to manage a switch in your

netw ork. It can a lso save you from having to g o to the d ifferent w iring

closets w here the switches are located.

For information on enhanced stacking and how to manag e different

switches from the same ma nag ement session, refer to Chapter 4,Enhanced Stackingon pag e 57.

Quitting from aLocal Session

To q uit a local session, return to the Main Menu and type Qfor Quit.

You should always exit from a manag ement session w hen you are

finished manag ing a sw itch. This can prevent unauthorized individuals

from making cha nges to a switchs configuration should you leave your

manag ement station unatt ended.

NoteYou cannot operate bo th a local manag ement session and a Telnet

manag ement session on the sa me switch simultaneously. Failure to

properly exit from a local or Telnet ma nagement session ma y block

future mana gement sessions.

Telnet Management Session

You can use the Telnet applicat ion protocol from a worksta tion on your

network to manag e an AT-8000 Series sw itch. This type of management

is referred to as remote manag ement because you do not ha ve to be

physically close to the switch to sta rt the session, such as w ith a local

manag ement session. Any workstat ion on your network tha t ha s theapplication protocol can be used to ma nag e the sw itch.

In terms of functionally, there are almost no d ifferences between

managing a switch loca lly throug h the RS232 Terminal Port and

remotely with the Telnet applicat ion protocol. You see the same menu

selections and ha ve nearly the same manag ement capa bilities.

Starting a Telnet mana gement session requires tha t there be a t least one

AT-8000 Series switch on your network that has an IP address. The sw itch

with the IP address is referred to as the master switch. Once you ha vestarted a Telnet mana gement session on t he master switch, you w ill

have management access to a ll the other AT-8000 Series switches thatreside in the same subnet .

Note

NoteFor ba ckground information on enhanced stacking , refer to

Enhanced Stacking Overviewon page 58.

Starting a TelnetManagement

Session

To start a Telnet ma nagement session, specify the IP add ress of the

master switch o f the enhanced stack in the Telnet applicat ion protocol

and enter the mana gement software password w hen prompted. The

default password for manager access is friend. The default passw ordfor operator access is operator. Log ins and pa sswords are case-

sensitive. For information on the tw o access levels, refer to

Management Access Levelson pag e 25.(For instructions on how tochange a password, refer to Configuring the Management Passwordson pag e 48.)

The Main Menu of a Telnet ma nagement session is the same menu tha t

you see in a local management session, shown in Figure 2 on pa ge 32.

When Does a Switch Need an IP Address?

One of the t asks to building or expand ing a network is deciding w hich of

the ma nag ed sw itches need to be assigned unique IP addresses. The

rule used to be that a ma nag ed switch needed an IP address if you

wanted to mana ge it remotely, such as w ith the Telnet application

protocol. How ever, if a network conta ined a lot of manag ed switches,having to a ssign each one an IP address wa s often cumbersome and

time consuming. It was also often difficult keeping track of a ll the IP

addresses.

The enhanced sta cking fea ture o f the AT-8000 Series sw itch simplifies a ll

this. With enhanced stacking, you need assign an IP address to only oneAT-8000 Series sw itch in each sub net in your network. The switch w ith

the IP ad dress is referred to as the Master switch of the subnetw ork. All

switches in the same subnet share the IP address.

Starting a local or remote manag ement session on the Master switch

automat ically gives you complete management access to all the otherswitches in the same subnet .

This feature has tw o primary benefits. First, it helps reduce the number

of IP ad dresses you ha ve to assign to your network devices. Second, it

allow s you to configure multiple switches through the same local or

remote manag ement session.

If your netw ork consists of multiple subnets, you must a ssign a unique IP

address to at least one sw itch in each subnet . The switch w ith the IP
