Chapter 1
Overview
This chapter describes the AT-S63 software functions, the types of
sessions you can use to access the software, and the management
access levels. This chapter contains the following sections:
❑ ”Management Overview” on page 22
❑ ”Local Management Session” on page 24
❑ ”Telnet Management Session” on page 25
❑ ”Web Browser Management Session” on page 26
❑ ”SNMP Management Session” on page 27
❑ ”Management Access Levels” on page 28
21
Chapter 1: Overview
Management Overview
The AT-S63 management software is intended for the AT-9400 Series
switches. You use the software to monitor and adjust the switch’s
operating parameters. Some of the functions you can perform with the
software include:
❑ Enable and disable ports
❑ Configure port parameters, such as 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), Rapid
Spanning Tree Protocol (RSTP), or Multiple Spanning Tree
Protocol (MSTP)
❑ Activate enhanced stacking functions
❑ Configure Quality of Service (QoS)
❑ Enable and configure Internet Group Management Protocol
(IGMP) snooping
❑ Download and upload image, configuration, and system files
❑ Configure port security
The AT-S63 management software is preinstalled on the switch with
default settings for all operating parameters. If the default settings are
adequate for your network, 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 switch.
Note
The default settings for the management software can be found in
Appendix A, ”AT-S63 Default Settings” on page 357.
To actively manage a switch by adjusting its operating parameters, you
must access the AT-S63 management software. The AT-S63
management software provides a menu interface that makes it very easy
to use (see the AT-S63 Management Software Menus Interface User’s
Guide), and an interface for managing a switch using a web browser
(described in this guide). It also features a command line interface (see
the AT-S63 Management Software Command Line Interface User’s Guide).
22
AT-S63 Management Software Web Browser Interface User’s Guide
There are four ways to access the management software on an AT-9400
Series switch. These methods are referred to in this guide as
management sessions. They are:
❑ Local management session
❑ Telnet management session
❑ Web browser management session
❑ SNMP management session
The following sections in this chapter briefly describe each type of
management session.
23
Chapter 1: Overview
Local Management Session
You establish a local management session with an AT-9400 Series switch
by connecting a terminal or a PC with a terminal emulator program to
the terminal port on the switch, using the RJ-45 to RS-232 management
cable included with the switch. The terminal port is located on the front
panel of the AT-9400 Series 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.
After the session starts, 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 using
the menus or CLI interface.
Note
For instructions on starting a local management session, refer to
Chapter 2, “Starting a Local or Telnet Management Session” in the
AT-S63 Management Software Menus Interface User’s Guide.
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 affect the forwarding of frames by the device.
Assigning an AT-9400 Series switch an IP address and designating it as a
master switch allows you to manage more than that switch. You can
manage all of the switches that support enhanced stacking that reside in
the same subnet, all from the same local management session.
Note
For further information on enhanced stacking, refer to Chapter 5,
“Enhanced Stacking,” in the AT-S63 Management Software Menus
Interface User’s Guide.
24
Telnet Management Session
You can use any management station on your network that has the
Telnet application to manage an AT-9400 Series switch. This type of
management session is referred to in this guide as a remote
management session because you do not need to be in the wiring closet
where the switch is located. You can manage the switch from any
workstation on the network that has the application protocol.
To establish a Telnet management session with a switch, there must be
at least one enhanced stacking switch in the subnet to which you
assigned an IP address. Only one switch in a subnet needs to have an IP
address. After you have established a Telnet management session with
the switch that has an IP address, you can use the enhanced stacking
feature of the management software to access all other switches that
support enhanced stacking that reside in the same subnet.
Note
For further information on enhanced stacking, refer to Chapter 5,
“Enhanced Stacking,” in the AT-S63 Management Software Menus
Interface User’s Guide.
AT-S63 Management Software Web Browser Interface User’s Guide
Note
For instructions on how to start a Telnet management session, refer
to Chapter 2, “Starting a Local or Telnet Management Session” in the
AT-S63 Management Software Menus Interface User’s Guide.
A Telnet management session provides access to nearly 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.
25
Chapter 1: Overview
Web Browser Management Session
You can also use a web browser to manage a switch. This too is 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. It also uses the enhanced stacking feature. This means
there needs to be just one switch on the subnet with an Internet
Protocol (IP) address for you to be able to manage all the switches with a
web browser. For instructions on starting this type of management
session, refer to Chapter 2, ”Starting a Web Browser Management
Session” on page 31.
26
SNMP Management Session
Another way to remotely manage the switch is with an SNMP
management program. A familiarity with using management
information base (MIB) objects is necessary for this type of management.
The AT-S63 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 MIBs
You must download the Allied Telesyn managed switch MIBs
(atistackinfo.mib and atiswitch.mib) file from the Allied Telesyn web site
and compile the files with your SNMP program. For instructions, refer to
your SNMP management documentation.
AT-S63 Management Software Web Browser Interface User’s Guide
Note
SNMP management does not use the enhanced stacking feature of
the switch. Therefore, you must assign an IP address to each switch
that you want to manage with an SNMP program.
27
Chapter 1: Overview
Management Access Levels
There are two levels of management access in the AT-S63 management
software: 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; you
cannot change any values.
You log in as a manager or an operator by entering the appropriate
username and password when you start an AT-S63 management
session. To log in as a manager, type “manager” as the login name. The
default password is “friend.” The username for operator is “operator” and
the default password is also “operator.” The usernames and passwords
are case sensitive.
To change the passwords, refer to ”Configuring the Manager and
Operator Passwords” on page 46.

Section I: Basic Features 31
Chapter 2: Starting a Web Browser Management Session
Starting a Web Browser Management Session
To establish a web browser management session with an AT-9400 Series
switch, there must be at least one switch in the subnet that has been
assigned an IP address and whose stacking status has been changed to
master switch. After you start a web browser management session on
the master switch, you can manage all the enhanced stacking switches
that reside in the same subnet.
If the subnet does not contain an enhanced stacking switch with an IP
address, then you must use the menus or the command line interface
(CLI) to give the switch an IP address and subnet mask. Then you can
connect to that switch and start a web browser management session.
Note
For background information on enhanced stacking, refer to Chapter
5, “Enhanced Stacking,” in the AT-S63 Management Software Menus
Interface User’s Guide.
Switch’s IP Address
To start a web browser management session, perform the following
procedure:
1. Start your web browser.
Note
If your PC with the web browser is connected directly to the switch
to be managed or is on the same side of a firewall as the switch, you
must configure your browser’s network options not to use proxies.
Consult your web browser’s documentation on how to configure
the switch’s web browser not to use proxies.
2. In the URL field of the browser, enter the IP address of the switch you
want to manage or of the master switch of the enhanced stack.

characters. The name can include spaces and special characters,
such as exclamation points and asterisks. The default is no name.
This parameter is optional.
Note
Allied Telesyn recommends assigning each switch a name. Names
make it easier for you to identify the various switches when you
manage them, and they can help you avoid performing a
configuration procedure on the wrong switch.
Administrator
This parameter specifies the name of the network administrator
responsible for managing the switch. The name can be from 1 to
20 characters. It can include spaces and special characters, such as
dashes and asterisks. The default is no name. This parameter is
optional.
Comments
This parameter specifies the location of the switch, (for example,
4th Floor - rm 402B). The location can be from 1 to 20 characters.
The location can include spaces and special characters, such as
dashes and asterisks. The default is no location. This parameter is
optional.
Section I: Basic Features 41
Chapter 3: Basic Switch Parameters
IP Address
This parameter specifies the IP address of the switch. You must
specify an IP address if you want the switch to function as the
Master switch of an enhanced stack. The IP address must be
entered in the format: xxx.xxx.xxx.xxx. The default value is 0.0.0.0.
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.
The subnet mask must be entered in the format: xxx.xxx.xxx.xxx.
The default value is 255.255.0.0.
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. The address must be entered in the format: xxx:xxx:xxx:xxx.
The default value is 0.0.0.0.
3. Click Apply to activate your changes on the switch.
Note
A change to any of the above parameters is immediately activated
on the switch.
A change to the IP address of the switch results in the loss of a
remote management session. You can restart the management
session using the switch’s new IP address.

Configuring the Manager and Operator Passwords
There are two levels of management access on an AT-9400 Series 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; you cannot
change any values.
You log in as a manager or an operator by entering the appropriate
username and password when you start an AT-S63 management session.
The default password for manager access is “friend.” The default
password for operator access is “operator.” Passwords are case sensitive.
To change the manager or operator password, perform the following
procedure:
1. From the home page, select Configuration.
The System page is displayed with the General tab selected by
default, as shown in Figure 5 on page 40.
2. In the Passwords section, enter the new values. The parameters are
described below.

You use these parameters to change the manager’s login
password for the switch. The password can be from 0 to 16
characters in length. The same password is used for both local and
remote management sessions. To create a new password, enter
the new password into both fields. The default password is
“friend.” The password is case sensitive.
Caution
Do not use spaces or special characters, such as asterisks (*) and
exclamation points (!), in a password if you are managing the switch
from a web browser. Many web browsers cannot handle special
characters in passwords.

Chapter 5: Enhanced Stacking
Setting a Switch’s Enhanced Stacking Status
The enhanced stacking status of the switch can be master, slave, or
unavailable. Each status is described below:
❑ Master - A master switch of a stack can be used to manage other
enhanced stacking switches in a subnet. After you have
established a local or remote management session with the
master switch, you can access and manage the other enhanced
stacking 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 client software on the switch so that the
switch automatically obtains an IP address from a BOOTP or
DHCP server on your network.
❑ Slave - A slave switch can be remotely managed through a master
switch. It does not need an IP address or subnet mask.
❑ 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. To be managed remotely, a
switch with an unavailable stacking status must be assigned a
unique IP address.
Note
The default setting for a switch is slave.
To adjust a switch’s enhanced stacking status, perform the following
procedure:
1. From the Home page, select Configuration.

Chapter 5: Enhanced Stacking
Selecting a Switch in an Enhanced Stack
Before you perform any procedure on a switch in an enhanced stack,
check to be sure that you are performing it on the correct switch. If you
assigned system names to your switches, identifying your switches is
easy. The AT-S63 management software displays the name of the switch
being managed at the top of every management menu.
When you start a web browser management session on the master
switch of the enhanced stack, you are by default addressing that
particular switch. The management tasks that you perform affect only
the master switch.
To manage a slave switch or another master switch in the same stack, 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 home page, select Enhanced Stacking.
Note
If the Home page does not have an Enhanced Stacking menu option,
the switch’s enhanced stacking status is either slave or unavailable.
For instructions on how to change a switch’s stacking status, refer to
the previous procedure:
68 Section I: Basic Features
AT-S63 Management Software Web Browser Interface User’s Guide
The master switch polls the network for the slave and master
enhanced stacking switches in the subnet and displays a list of the
switches in the Stacking Switches page. An example is shown in
Figure 16.
Figure 16. Stacking Switches Page
Note
The master switch on which you started the management session is
not included in the list, nor are any switches with an enhanced
stacking status of Unavailable.
You can sort the switches in the list by switch name or MAC
address by clicking on the column headers. By default, the list is
sorted by MAC address.
To refresh the list, click Refresh. This instructs the master switch
to again poll the subnet for all switches.
2. To manage another switch in an enhanced stack, click the button to
the left of the appropriate switch in the list. You can select only one
switch at a time.
Note
If the web server on the master switch is operating in the secure
HTTPS mode, you can manage only those enhanced stacking
switches that are also operating HTTPS. You cannot manage a
switch whose web server is operating in the non-secure HTTP mode.
3. Click Connect.
Section I: Basic Features 69

74 Section I: Basic Features
AT-S63 Management Software Web Browser Interface User’s Guide
The Port Configuration page is shown Figure 19.
Figure 19. Port Configuration Page
6. Adjust the following parameters as necessary.
Port Name
Use this selection to assign a name to a port. The name can be
from one to fifteen alphanumeric characters. Spaces are allowed,
but you should not use special characters, such as asterisks or
exclamation points. (You cannot assign a name when you are
configuring more than one port.)
Status
Use this selection to enable or disable a port. When disabled, a
port does not accept or forward frames.
You might want to disable a port and prevent packets from being
forwarded if a problem occurs with the node or cable connected
to the port. After the problem has been fixed, you can enable the
port again to resume normal operation.
You might also want to disable a port that is not being used to
secure it from unauthorized connections.
The possible settings are:
Enabled - The port receives and forwards packets. This is the
default setting.
Section I: Basic Features 75
Chapter 6: Port Parameters
Disabled - The port does not receive or forward packets.
Speed and Duplex
You use this selection to configure a port for autonegotiation or to
manually set a port’s speed and duplex mode.
If you select Auto-Negotiate for autonegotiation, which is the
default setting, the switch sets both speed and duplex mode for
the port automatically.
Note the following about the operation of autonegotiation on the
switch port:
❑ In order for a switch port to successfully autonegotiate its duplex
mode with an end node, the end node should also be using
autonegotiation. Otherwise, a duplex mode mismatch can occur.
A switch port using autonegotiation defaults to half-duplex if it
detects that the end node is not using autonegotiation. This
results in a mismatch if the end node is operating at a fixed duplex
mode of full-duplex.
To avoid this problem, when connecting an end node with a fixed
duplex mode of full-duplex to a switch port, you should disable
autonegotiation on the port and set the port’s speed and duplex
mode manually.
❑ If you disable autonegotiation on a port, the auto-MDI/MDI-X
feature on a port is also disabled, and the port defaults to the MDIX configuration. Consequently, if you disable autonegotiation and
set a port’s speed and duplex mode manually, you might also
need to set the port’s MDI/MDI-X setting as well.
Auto-Negotiate: The port autonegotiates both speed
(10/100/1000 Mbps) and duplex mode. This is the default.
The other possible settings are:
10Mbps - Half Duplex
10Mbps - Full Duplex
100Mbps - Half Duplex
100Mbps - Full Duplex
Note
When a transceiver is inserted into an uplink slot and a link is
established, that slot becomes a primary uplink port and the
corresponding backup port, 23R or 24R, automatically transitions to
redundant uplink status. The speed and duplex mode of the
76 Section I: Basic Features
AT-S63 Management Software Web Browser Interface User’s Guide
redundant port automatically transitions to Auto-Negotiate to
match the speed of the primary uplink port and you cannot
configure the MDI/MDIX crossover parameter.
Note
1000 Mbps speed is only available when you set the port to
autonegotiate. You cannot set this manually.
If you select all ports, the Speed and Duplex setting displays “Not
Configurable,” because all ports are set to autonegotiate.
Broadcast Filter
Use this parameter to limit the number of ingress broadcast
packets the port receives. The possible settings are:
Enabled - The port does not receive any broadcast packets.
Disabled - The port receives broadcast packets. This is the default
setting.
For further information about filters, refer to Chapter 6, “Port
Parameters,” in the AT-S63 Management Software Menus Interface
User’s Guide.
Unknown Unicast Filter
Use this parameter to limit the number of ingress unknown
unicast packets the port receives. The possible settings are:
Enabled - The port does not receive any unknown unicast packets.
Disabled - The port receives unknown unicast packets. This is the
default setting.
Unknown Multicast Filter
Use this parameter to limit the number of ingress unknown
multicast packets the port receives. The possible settings are:
Enabled - The port does not receive any unknown multicast
packets.
Disabled - The port receives unknown multicast packets. This is
the default setting.
Flow Control
Sets flow control on a port. This option only applies to ports
operating in full-duplex mode. A switch port uses back pressure to
control the flow of ingress packets. The switch sends a special
pause packet to stop the end node from sending frames. The
Section I: Basic Features 77
Chapter 6: Port Parameters
pause packet notifies the end node to stop transmitting for a
specified period of time. The possible settings are:
Auto - The port uses flow control if it detects that the end node is
using it.
Disabled - No flow control on the port. This is the default.
Enabled - Flow control is activated.
For further information about flow control, refer to Chapter 6,
“Port Parameters,” in the AT-S63 Management Software Menus
Interface User’s Guide.
Back Pressure
Use this parameter to set back pressure on a port. This option only
appears for ports operating in half-duplex mode. A switch port
uses back pressure to control the flow of ingress packets. The
possible settings are:
Enabled - Back pressure is enabled.
Disabled - Back pressure is disabled. This is the default.
For further information about back pressure, refer to Chapter 6,
“Port Parameters,” in the AT-S63 Management Software Menus
Interface User’s Guide.
Flow Control/Back Pressure Limit
Use this parameter to specify the maximum number of ingress
packets that a port receives within a one second period before
initiating flow control or back pressure. The range is 1 to 7935
cells. The default is 561.
The following three parameters allow you to set rate limiting, the
maximum number of ingress packets a port accepts each second.
Packets exceeding the threshold are discarded.
Broadcast Rate Limit
Use this parameter to enable or disable ingress broadcast packet
limits and specify a rate limit for the ingress broadcast packets.
The possible settings are:
Enabled - Broadcast packet ingress rate limiting is enabled.
Disabled - Broadcast packet ingress rate limiting is disabled. This is
the default.
You can also set the rate limit in packets per second. The range is
0 to 262143. The default is 262143.

can enter only one port.
If you are entering a static multicast address, you must specify the
port when the multicast application is located as well as the ports
where the host nodes are connected. Assigning the address only
to the port where the multicast application is located results in the
failure of the multicast packets to be properly forwarded to the
host nodes. You can specify the ports individually (e.g., 1,4,5), as a
range (e.g., 11-14) or both (e.g., 15-17,22,24).

The type of the address: static or dynamic.
96 Section I: Basic Features
Changing the Aging Time
The switch uses the aging time to delete inactive dynamic MAC
addresses from the MAC address table. When the switch detects that no
packets have been sent to or received from a particular MAC address in
the table after the period specified by the aging time, the switch deletes
the address. This prevents the table from becoming full of addresses of
nodes that are no longer active.
The default setting for the aging time is 300 seconds (5 minutes).
To adjust the aging time, perform the following procedure:
1. From the Home page, select Configuration.
The System page is displayed with the General tab selected by
default, as shown in Figure 5 on page 40.

Chapter 8: Port Trunking
Creating a Port Trunk
Caution
Do not connect the cables of a port trunk to the ports on the switch
until after you have configured the ports on both the switch and the
end node. Connecting the cables prior to configuring the ports can
create loops in your network topology. Loops can result in
broadcast storms, which can adversely effect the operation of your
network.
If you are deleting a port trunk, disconnect the cables from the ports
before you delete the trunk. Deleting the trunk without first
disconnecting the data cables can create a loop in your network
topology, which can result in broadcast storms.
To create a port trunk, perform the following procedure:
1. From the home page, select Configuration.
The System page is displayed with the General tab selected by
default, as shown in Figure 5 on page 40.
2. From the Configuration menu, select the Layer 1 option.
