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.

Chapter 1
AT-S60 Overview
This chapter describes the AT-S60 software functions, the types of
sessions you can use to access the software, and the management
access levels. This chapter contains the following sections:
❑ Overview on page 25
❑ Local Management Session on page 26

Section I: Overview 24
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.
Section I: Overview 29
Chapter 1: AT-S60 Overview
Management Access Levels
There are two levels of management access on an AT-8400 switch:
Manager and Operator. When you log in as a Manager, you can view and
configure all of a switch’s operating parameters. When you log in as an
Operator, you can only view the operating parameters. As an Operator,
you cannot change any values.
To log in, you enter a login id of Manager or Operator and the
appropriate password when you start an AT-S60 management session.
For Manager access, enter the following at the prompts:
Login: manager
password: friend
For Operator access, enter the following at the prompts:
Login: operator
password: operator
The password is case-sensitive for both Manager and Operator access.
There are a total of 14 login sessions available using the local, Telnet, and
web browser management sessions. However, you can have only one
Manager session on the switch regardless of how you or others are
accessing the switch. There are additional limitations for the different
types of management sessions. The local and Telnet sessions allow a
total of 10 active sessions. While a web browser management session,
allows four active login sessions.
Section I: Overview 30
Specifying Ports
AT-S60 Management Software User’s Guide
Many of the commands and parameters, in this manual involve
specifying the port(s) on the switch. Port numbers are specified in the
following format:
slot.port
Slot is the number of the slot in the switch that contains the line card.
There are twelve line card slots in the AT-8400 chassis. Port is the port
number on the line card. For example, to indicate port 4 on the line card
in Slot 8, enter:
8.4
In many commands, you can specify a list of ports. You can list ports on
the same line card individually, as a range, or both. The following
example refers to Ports 1, 3, and 5 through 8 on the line card in Slot 3:
3.1,3,5-8
Some commands can be performed on ports on different line cards. This
example refers to Ports 1 and 4 on the line card in Slot 4 and Ports 6
through 8 on the line card in Slot 11:
4.1,4,11.6-8
Section I: Overview 31
Chapter 1: AT-S60 Overview
Specifying Time and Date
The Simple Network Time Protocol (SNTP) feature places the time and
date on the local and telnet interfaces. The time and date appear in the
upper right hand corner of the menu. See Figure 1.

When you access remote switches using the enhanced stacking feature,
the time and date set by the local switch appears. It is possible for a local
switch and a remote switch to display different time stamps. For
example, if you are using a switch in one time zone it displays the local
time. If you access a remote switch which is located in a different time
zone, the time on that switch reflects local time.
For information about how to configure the time and date, see Setting
the System Time on page 52.

Chapter 2
Starting a Local or Telnet Management Session
This chapter contains the procedure for starting a local or Telnet
management session on an AT-8400 Series switch. It contains the
following sections:
❑ Local Management Session on page 35
❑ Telnet Management Session on page 39
Section II: Local and Telnet Management 34
Local Management Session
To establish a local management session using the AT-S60 management
software, connect an RS-232 straight-through cable to the RS-232
terminal port on the AT-8400 chassis. Connect the other end of the cable
to a terminal or a PC with a terminal emulator program.
A local management session is so named because you must be
physically close to the switch, usually within a few meters, to start this
type of management session. A local management session requires you
to connect a terminal directly to the switch. Typically, this means that
you are in the wiring closet where the switch is located.
A switch does not need an IP address to be managed from a local
management session. You can start a local management session at any
time on any AT-8400 switch in your network. Running a local
management session does not interfere with the flow of Ethernet traffic
through the unit.
AT-S60 Management Software User’s Guide
Starting a local management session on a switch that has been
configured as a Master switch of an enhanced stack allows you to
manage all the switches in the subnet from the same local management
session. You do not have to start a separate local management session
for each switch. This can simplify network management.
There are a total of 14 login sessions available using the local, Telnet, and
web browser management sessions. However, you can have only one
Manager session on the switch regardless of how you or others are
accessing the switch. There are additional limitations for the different
types of management sessions. The local and Telnet sessions allow a
total of 10 active sessions. While a web browser management session,
allows four active login sessions.

Enhanced
Stacking
Quitting from a
Local Session
When you start a management session on an AT-8400 (or an Allied
Telesyn switch that supports Enhanced Stacking) that has been
designated as the Master switch of an enhanced stack, you can manage
all the switches in the same subnet from one management session. This
can save you time because you do not have to start a separate local
management session each time you want to manage each switch in your
network. It can also save you from having to go to the individual wiring
closets where the switches are located.
For information on enhanced stacking and how to manage different switches from the same management session, refer to Chapter 2, Enhanced Stacking on page 79.
To quit a local session, return to the Main Menu and type Q for Quit.
Allied Telesyn recommends that you exit from a management session
when you are finished managing a switch. This can prevent
unauthorized individuals from making changes to a switch’s
configuration should you leave your management station unattended.
Note
The AT-S60 management software automatically ends a
management session if it does not detect any activity from the local
management station after the specified period of time. The default
value of the local timeout is 10 minutes. To change this setting, refer
to Configuring the AT-S60 Software Security Features on page
57.
Section II: Local and Telnet Management 38
Telnet Management Session
You can use the Telnet application protocol from a workstation on your
network to manage an AT-8400 switch. This type of management is
referred to as remote management because you can be physically far
from the switch when you start the session. (In contrast to a local
management session, which requires that you connect a terminal
directly to the switch.) Any workstation on your network that has the
Telnet application protocol can be used to manage the switch.
In terms of functionally, there are almost no differences between
managing a switch locally through the RS-232 Terminal Port and
remotely with the Telnet application protocol. You see the same menu
selections and have nearly the same management capabilities. However,
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 with a xmodem connection.
AT-S60 Management Software User’s Guide
Starting a Telnet management session requires that there be at least one
AT-8400 Series switch on your network that has an IP address. The switch
with the IP address is referred to as the master switch. Once you have
started a Telnet management session on the master switch, you have
management access to all the other AT-8400 Series switches as well as all
the Allied Telesyn switches that reside in the same subnet.
There are a total of 14 login sessions available using the local, Telnet, and
web browser management sessions. However, you can have only one
Manager session on the switch regardless of how you or others are
accessing the switch. There are additional limitations for the different
types of management sessions. The local and Telnet sessions allow a
total of 10 active sessions. While a web browser management session,
allows four active login sessions.

Section II: Local and Telnet Management 41
Chapter 3:Basic Switch Parameters
Assigning an IP Address to a Switch
When building or expanding your network, you need to decide which
managed switches need an unique IP addresses. The rule used to be that
a managed switch needed a IP address if you wanted to manage it
remotely, such as with the Telnet application protocol. However, if a
network contained a lot of managed switches, assigning each one an IP
address was often cumbersome and time consuming. Also, it was often
difficult keeping track of all the IP addresses.
The enhanced stacking feature of the AT-8400 switch simplifies when to
assign an IP address. With enhanced stacking, you need assign an IP
address to only one AT-8400 or other Allied Telesyn switch that supports
enhanced stacking, for each subnet in your network. The switch with the
IP address is referred to as the Master switch of the subnetwork. All
switches in the same subnet share the IP address.
Starting a local or remote management session on the Master switch
automatically gives you complete management access to all the other
switches in the same subnet.
This feature has two primary benefits. First, it helps reduce the number
of IP addresses you have to assign to your network devices. Second, it
allows you to configure multiple switches through the same local or
remote management session.
If your network consists of multiple subnets, you must assign a unique IP
address to at least one switch in each subnet. The switch with the IP
address is the Master switch of that subnet.
Note
For further information on enhanced stacking, refer to Enhanced
Stacking Overview on page 80.
When you assign a switch an IP address, you must also assign it a subnet
mask. The switch uses the subnet mask to determine which portion of an
IP address represents the network address and which portion represents
the node address.
You must also assign the switch a gateway address if there is a router
between the switch and the remote management workstation. This
gateway address is the IP address of the router through which the switch
and management station communicates.
If you do not plan to remotely manage any of the AT-8400 switches in
your network, then you do not need to assign an IP address to any of
them. The switches operate fine without an IP address and you are still
able to manage them completely using the local management interface.
Section II: Local and Telnet Management 42
AT-S60 Management Software User’s Guide
How Do You
Assign an IP
Address?
Once you have decided which, if any, switches on your network need an
IP address, you have to access the AT-S60 software on the switches and
assign the address or addresses. There are actually two ways in which
you can assign a switch an IP address.
The first method is to assign the IP configuration information manually.
This method is explained in the next procedure, Configuring an IP
Address and Switch Name on page 44. Initially, assigning an IP address
to a switch can only be done through a local management session.
The second method is to activate the BOOTP and DHCP services on the
switch and have the switch automatically download its IP configuration
information from a BOOTP or DHCP server on your network. This
procedure is explained in Activating the BootP and DHCP Services on
page 50.
Section II: Local and Telnet Management 43
Chapter 3:Basic Switch Parameters
Configuring an IP Address and Switch Name
The procedure in this section explains how to manually assign an IP
address, subnet mask, and gateway address to the switch using a local or
Telnet management session. Initially, it must be done from the local
management interface. (If you want the switch to obtain its IP
configuration from a DHCP or BOOTP server on your network, go to the
procedure Activating the BootP and DHCP Services on page 50.)
In addition, this procedure explains how to assign a name to the switch,
along with other optional information, such as the name of the
administrator responsible for maintaining the unit and the location of
the switch.
To manually set a switch’s IP address, perform the following procedure:
1. From the Main Menu, type 4 to select Administration Menu.
The Administration Menu is shown in Figure 4.

2. Change the parameters as desired.
The parameters in the Administrative Menu are described below:
1 - IP Address
This parameter specifies the IP address of the switch. You must
specify an IP address if you intend to remotely manage the switch
using a web browser, a Telnet utility, or an SNMP management
program, or if you want a switch to function as the Master switch
of an enhanced stack.
2 - Subnet Mask
This parameter specifies the subnet mask for the switch. You must
specify a subnet mask if you assigned an IP address to the switch.
3 - Default Gateway
This parameter specifies the default router’s IP address. This
address is required if you intend to remotely manage the switch
from a management station that is separated from the switch by
a router.
4 - System Name
This parameter specifies a name for the switch (for example, Sales
Ethernet switch). This parameter is optional.
Note
Allied Telesyn International recommends that you assign each
switch a name because names help you identify the various
switches when you manage them. In addition, switch names help
you avoid performing a configuration procedure on the wrong
switch.
5 - Administrator
This parameter specifies the name of the network administrator
responsible for managing the switch. This parameter is optional.

Chapter 3:Basic Switch Parameters
Activating the BootP and DHCP Services
The BootP and DHCP application protocols were developed to simplify
network management. They are used to automatically assign IP
configuration information—such as an IP address, subnet mask, and a
default gateway address—to the devices on your network.
An AT-8400 switch supports these protocols and can obtain its IP
configuration information from a BootP or DHCP server on your
network. If you activate this feature, the switch seeks its IP address and
other IP configuration information from a BootP or DHCP server on your
network whenever you reset or power cycle the switch.
Naturally, for this to work there must be a BootP or DHCP server residing
on your network and you must configure the service by entering in the
switch’s MAC address. The MAC address is located on a sticker on the
power supply cover (on the front of the chassis).
BootP and DHCP services typically allow you to specify how the IP
address is assigned to the switch. The choices are static and dynamic. If
you choose static, the server always assigns the same IP address to the
switch when the switch is reset or powered ON. This is the preferred
configuration. Because the BootP and DHCP services always assigns the
same IP address to a switch, you know which IP address to use when you
need to remotely manage a particular switch.
If you specify the IP address as dynamic, the server assigns the switch
any unused IP address. As a result, a switch might have a different IP
address each time you reset or power cycle the device, making it difficult
for you to remotely manage the unit.
Note
By default, the BootP and DHCP option is disabled on the switch.
To activate or deactivate the BootP and DHCP protocols on the switch,
perform the following procedure:
1. From the Main Menu, type 4 to select Administration Menu.
The Administration Menu in Figure 4 on page 44 is displayed.
2. From the Administration Menu, type 8 to select BOOTP/DHCP.
The following prompt is displayed:
BOOTP/DHCP (E-Enabled, D-Disabled):
3. Type E to enable BOOTP and DHCP services on the switch or D to
disable the services. Then press Return. The default is disabled.
Section II: Local and Telnet Management 50
AT-S60 Management Software User’s Guide
Note
If you activate BOOTP/DHCP, the switch immediately begins to
query the network for a BOOTP or DHCP server. The switch
continues to query the network for its IP configuration until it
receives a response.
4. After making changes, type R to return to the Main Menu. Then type
S to select Save Configuration Changes.
Section II: Local and Telnet Management 51
Chapter 3:Basic Switch Parameters
Setting the System Time
To set system time on the switch, configure the Simple Network Time
Protocol (SNTP). This feature allows you to synchronize computer clocks
on the Internet by specifying the difference between local time and
Universal Coordinated Time (UTC). You can either set the system time
manually every time you boot the switch or you can set the system time
with an SNTP server.
SNTP is a reduced version of the Network Time Protocol (NTP). However,
it is important to note that SNTP servers and clients are interoperable
with NTP servers and clients.
Note
If SNTP is disabled, or you have not configured an SNTP server, the
system time defaults to midnight of January 1, 1970.
Use the following procedure to configure the system date and time for
your switch.
1. From the Main Menu, type 5 to select System Menu.
The System Menu is shown in Figure 5 on page 47.
2. From the System Menu, type 1 to select Configure System.

Configuring the AT-S60 Software Security Features
The AT-S60 software has several security features that can help prevent
unauthorized individuals from changing the parameter settings of an
AT-8400 switch. The security features are:
❑ Manager and Operator Passwords - The management software
has two standard, management login accounts: Manager and
Operator. The Manager account allows you to configure all switch
parameters, while the Operator account only allows you to view
the parameter settings. The default login password for Manager
access is “friend.” The default password for Operator access is
“operator.” The passwords are case-sensitive. For instructions on
how to change a password, refer to Configuring the
Management Passwords on page 58.
❑ Console Timeout - This parameter causes the management
software to automatically end a management session if it does
not detect any activity from the local or remote management
station after the specified period of time. This security feature can
prevent unauthorized individuals from using your management
station should you step away from your system while configuring
a switch. The default for the console timeout value is 10 minutes.
For instructions on how to set this security feature, refer to
Configuring Management Access on page 59.
❑ Web Access - You can disable the web browser management
feature to prevent individuals from managing the switch
remotely using a web browser. For instructions on how to set this
security feature, refer to Configuring Management Access on
page 59.
❑ Telnet Access - You can disable the Telnet server to prevent
individuals from managing the switch remotely using the Telnet
application. For instructions on how to set this security feature,

SNMP Community Strings
The procedures in this chapter allow you to create and modify SNMP
communities that have access to the switch. When you create an SNMP
community, you can specify SNMP management station IP addresses as
well as trap receiver IP addresses. The following procedures are
provided:
❑ Enabling SNMP Communities on page 69
❑ Configuring SNMP Communities on page 71
❑ Deleting a SNMP Community on page 74
❑ Modifying a SNMP Community on page 75
❑ Displaying a SNMP Community on page 78

Enabling SNMP Communities
To configure SNMP, you need to enable SNMP on your switch.
Then you can enable authentication failure traps. However, this is
an optional step.
Traps generated by the SNMP agent are forwarded to all trap
receivers in all of the SNMP communities. (For information about
configuring the trap host receiver IP addresses and the SNMP
management stations, see Configuring SNMP Communities on
page 71.) The SNMP community name and manager IP addresses
are used to provide authentication. An incoming SNMP message
is deemed authentic if it contains a valid community name and it
originated from an IP address that is defined as a management
station for that community.
When a community is disabled, the SNMP agent behaves as if the
community does not exist. In addition, the switch generates
authentication failure traps for messages directed to the disabled
community.
AT-S60 Management Software User’s Guide
SNMP authentication is a mechanism where an SNMP message is
declared to be authentic. The authentication failure trap may be
generated as a result of the failure to authenticate an SNMP
message. See the procedure below for instructions on how to
enable or disable the generation of authentication failure traps.
To enable SNMP and authentication trap messages, perform the
following procedure.
1. From the Main Menu, type 5 to select System Menu.
The System Menu is shown in Figure 5 on page 47.
2. From the System Menu, type 1 to select Configure System.

Enhanced Stacking
This chapter explains the enhanced stacking feature and provides
procedures for using this feature with a local or Telnet management
session. This chapter contains the following sections:
❑ Enhanced Stacking Overview on page 80
❑ Setting a Switch’s Enhanced Stacking Status on page 83
❑ Selecting a Switch in an Enhanced Stack on page 85
Section II: Local and Telnet Management 79
Chapter 5: Enhanced Stacking
Enhanced Stacking Overview
The enhanced stacking feature can make it easier for you to manage an
AT-8400 and any other ATI switches in your network that feature
enhanced stacking. It offers the following benefits:
❑ From one local or remote management session, you can manage
up to 24 switches. This eliminates having to initiate a separate
management session for each switch in your network. For
example, with the AT-8400 switch as the master switch, you can
manage AT-8000 Series switches that are configured with the
AT-S39 software version 3.1 and above.
❑ You can assign an IP address to the master switch. In addition, you
can manage slave switches without assigning them individual IP
addresses.This feature reduces the number of IP addresses that
you need to assign to your network devices for remote
management.
❑ Remotely managing a new switch in your network is simplified.
You simply connect it to your network. Once connected to the
network, you can begin to manage it immediately from any
workstation in your network.
Guidelines There are a few guidelines to keep in mind when implementing
enhanced stacking for your network:
❑ Each subnet in your network constitutes an enhanced stack. You
cannot have multiple enhanced stacks in a subnet.
❑ All switches within an enhanced stack must use the same
management VLAN. For information on management VLANs,
refer to Specifying a Management VLAN on page 272.
❑ Different enhanced stacks can use different management VLANs.
❑ Each subnet must have at least one master switch. Allied Telesyn
recommends you assign two master switches to an enhanced
stack.
❑ You must assign the master switch an IP address and subnet mask.
❑ You must change the master switch’s stacking status to Master.
❑ The enhanced stacking feature uses the IP address 176.16.16.16.
Do not assign this address to any device on your subnet if you
intend to use the enhanced stacking feature.
Section II: Local and Telnet Management 80
AT-S60 Management Software User’s Guide
There are three basic steps to implementing this feature on your
network:
1. You must select a switch in your network to function as the master
switch of the stack.
You can select an AT-8400, or any other ATI switch that is capable
of enhanced stacking, to act as the master switch of an enhanced
stack. For networks that consist of more than one subnet, there
must be at least one master switch in each subnet.
Allied Telesyn recommends that you assign two master switches
to each subnet. That way, if you remove one of the master
switches from the network, such as for maintenance, you are able
to remotely manage the switches in the subnet using the second
master switch.
Note
Only switches connected to the management VLAN of the master
switch can be discovered and managed through enhanced
stacking. Switches that are not connected to the management VLAN
are not discovered even if they are in the same subnet as the master
switch.
2. You must assign the master switch an IP address and a subnet mask.
A master switch must have an IP address and subnet mask. The
other switches in an enhanced stack, referred to as slave switches,
do not.
If your enhanced stack has more than one master switch, you
must assign a unique IP address to each master switch.
You can set an IP address manually or activate the BOOTP and
DHCP services on a master switch and have the master switch
obtain its IP information from a BOOTP or DHCP server on your
network. Initially, assigning an IP address or activating the BOOTP
and DHCP services can only be performed through a local
management session.
Note
For instructions on how to set the IP address manually, refer to
Configuring an IP Address and Switch Name on page 44. For
instructions on activating the BOOTP and DHCP services, refer to
Activating the BootP and DHCP Services on page 50.
3. You must change the enhanced stacking status of the master switch
to Master.

Figure 21 Enhanced Stacking Example
The example shown in Figure 21 consists of a network of two subnets
interconnected by a router. Two switches in each subnet have been
selected as the master switches of their respective subnets, and each has
been assigned a unique IP address.
To manage the switches of a subnet, you start a local management
session or a remote Telnet management session with one of the master
switches in the subnet. Then, you have management access to all the AT8400 switches in the same subnet.
Section II: Local and Telnet Management 82
Setting a Switch’s Enhanced Stacking Status
The enhanced stacking status of the switch can be master switch, slave
switch, or unavailable. Each status is described below:
❑ Master switch - A master switch of a stack can be used to manage
all the other switches in a subnet. You can assign the master status
to either an AT-8400, or any other ATI switch that features
enhanced stacking, which can then be used to manage a mixture
of AT-8400 and AT-8000 Series switches. Once you have
established a local or remote management session with the
master switch, you can access and manage all the switches in the
subnet.
A master switch must have a unique IP address. You can
manually assign a master switch an IP address or activate the
BOOTP and DHCP services on the switch.
❑ Slave switch - A slave switch can be remotely managed through a
master switch. It does not need an IP address or subnet mask.
AT-S60 Management Software User’s Guide
❑ Unavailable - A switch with an unavailable stacking status cannot
be remotely managed through a master switch. A switch with this
designation can be managed locally.
Note
You can use Telnet or the Web to manage a switch with an
unavailable stacking status remotely. However, the switch must be
directly connected to the AT-8400 and you must assign it a unique
IP address.
Note
The default setting for a switch is Slave.

Selecting a Switch in an Enhanced Stack
Before performing a procedure on a switch, check that you are accessing
the correct switch. If you assigned system names to your switches, this is
a simple check. The name of the switch you are currently managing is
displayed at the top of every management menu. For example, in Figure
23, the name of the switch is Sales Switch 591.
When you start a management session on the Master switch of a subnet,
you are, by default, addressing that particular switch. The management
tasks that you perform effect only the master switch.
To manage a slave switch or another Master switch in the subnet, you
need to select it from the management software.
To select a switch to manage in an enhanced stack, perform the
following procedure:
1. From the Main Menu, type 8 to select Enhanced Stacking.

Chapter 6: Port Parameters
4. Adjust the port parameters as desired. You adjust a parameter by
typing its number. This toggles the parameter through its possible
settings. The parameters are described below.
0 - Port Name
This parameter appears only if you are configuring a single port.
You can use this selection to assign a name to a port. The name
can be up to fifteen alphanumeric characters. Spaces are allowed.
1 - Status
You use this selection to change the administrative status of a
port. When disabled, a port does not forward frames.
You might want to disable a port and prevent frames from being
forwarded if a problem occurs with the node or cable connected
to the port. Once the problem has been fixed, you can enable the
port again to resume normal operation. You can also disable an
unused port to secure it from unauthorized connections.
Press 1 to toggle between the following settings:
Enabled - The port is able to send and receive Ethernet frames.
This is the default setting for all ports on the switch.
Disabled - The port is not able to send or receive Ethernet frames.
2 - Broadcast Filter
You use this selection to protect a port from a deluge of packets
caused by a broadcast storm. Enabling the broadcast filter
parameter on a port causes the port to drop broadcast frames.
Press 2 to toggle between the following settings:
Enabled - When a port receives a broadcast frame, the port drops
the frame.
Disabled - The port does not watch for broadcast frames. Instead,
it accepts broadcast frames. This is the default.
3 - Override Priority
You use this selection to determine frame priority. For information
about override priority, see Class of Service Overview on page
320.
Press 3 to toggle between the following settings:
No override - Indicates that no override priority is assigned to
incoming frames. Instead, the port forwards frames according to
the priority embedded in the frame. This is the default.
Low Priority - Indicates low priority has been assigned to the port.
All ingress tagged and untagged frames received on the port are
forwarded to the egress port’s low priority queue.
Section II: Local and Telnet Management 94
AT-S60 Management Software User’s Guide
High Priority - Indicates high priority has been assigned to the
port. All ingress tagged and untagged frames received on the port
are forwarded to the egress port’s high priority queue.
4 - HOL Blocking
You use this selection to prevent a frame from being forwarded to
a blocking or blocked port. For example, a blocking or blocked
port can be one that is receiving too many frames.
Press 4 to toggle between the following settings:
Enabled - Indicates HOL blocking is turned on. Frames sent from
this port are not forwarded to a blocked port.
Disabled - Indicated HOL blocking is turned off. Frames sent from
this port are not prevented from being forwarded to a blocked
port. This is the default.
5 - Back Pressure
You can use this selection only if the port or ports you specified
are operating at half-duplex mode. When you configure a port in
this mode and it has a frame that is pending transmission, the port
uses the JAM signal when its buffer is full to prevent the end node
from sending any more frames.
Press 5 to toggle between the following settings:
Enabled - Indicates back pressure is activated on this port. When
the port is receiving too many frames, the port sends a signal to
the end node to stop sending information.
Disabled - Indicates back pressure is not activated on this port.
When the port is receiving too many frames, the port does not
send a signal to the end node to stop sending information.This is
the default.
Note
The Auto setting is not available if you set a port’s speed and duplex
mode manually.
6 - Flow Control
Flow control applies only to ports operating in full-duplex mode.
The switch uses a special pause frame when its buffer is full to stop
the end node from sending frames. The pause frame notifies the
end node to stop transmitting for a specified period of time.
Press 6 to toggle between the following settings:
Auto - Indicates the port conforms to the flow control setting of
the end node. For example, if flow control is active on the end
node then flow control is active on this port. Also, if flow control is
not active on the end node, then flow control is not active on this
port. This is the default.
Section II: Local and Telnet Management 95
Chapter 6: Port Parameters
Disabled - Indicates that no flow control occurs on the port.
Enabled - Indicates that flow control occurs on the port.
7 - Negotiation
You use this selection to configure a port for Auto-Negotiation or
to manually set a port’s speed and duplex mode.
Press 7 to toggle between the following settings:
Auto - Select Auto (for Auto-Negotiation) to set both speed and
duplex mode for the port automatically.
Note
For the AT-8412/SC FX and AT-8214/MT FX line cards, the default
setting on the Negotiation parameter is Manual. The default setting
for ports on all the other line cards is Auto.
Manual - Select Manual to set the speed and duplex for the port.
If you select Manual, three additional selections are displayed in
the Port Configuration menu:
8 - Speed ................. 0100
9 - Duplex ................ Full
A - MDI/MDIX Crossover .... MDIX
You use these selections to set a port’s speed, duplex mode, and
MDI/MDI/X settings. The possible settings for the 8 - Speed
selections are:
0010 - Indicates 10 Mbps.
0100 - Indicates 100 Mbps.
