Preface
This guide contains instructions on how to use the AT-S80 management
software to monitor and manage the AT-FS750/16 and AT-FS750/24 Fast
Ethernet Smart switches.
The AT-S80 Management Software has two management interfaces: a
menus interface and a web browser interface. You access the menus
interface through the console port on the switch. You access 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.
Note
The AT-S80 management software does not support remote
management with the Telnet application protocol or an SNMP
program.
Note
The interface illustrations in this book show the interface for the
AT-FS750/16 Fast Ethernet Smart Switch in the menus section and
the interface for the AT-FS750/24 Fast Ethernet Smart Switch in the
web section of the book. The AT-S80 software features are identical
in both switches with the exception of the number of ports displayed.
This preface contains the following sections:

Chapter 1
Overview
This chapter provides an overview of the AT-S80 Management Software
for the AT-FS750/16 and AT-FS750/24 switches. This chapter contains
the following sections:
“Management Overview” on page 18
“Remote SNMP Management” on page 20
“Management Access Level” on page 21
“Ports 17 and 18 on the AT-FS750/16 Switch and Ports 25 and 26 on
the AT-FS750/24 Switch” on page 22

Chapter 1: Overview
Management Overview
The AT-S80 Management Software allows you to view and adjust the
operating parameters of the AT-FS750/16 and AT-FS750/24 Fast
Ethernet Switches. A few examples of the management functions are
listed here:
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 port-based and tagged virtual LANs
Configure 802.1x port-based network access control
The AT-S80 management software comes preinstalled on the switch with
default settings for all of the switch’s operating parameters. Managing the
switch is not required 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 and powering on the unit, as explained in the hardware
installation guide.
Note
The default settings for the management software are listed in
Appendix A, “AT-S80 Software Default Settings” on page 339.
In order to actively manage the switch and adjust its operating
parameters, you must access the switch’s AT-S80 management software.
You can access the management software using one of the following
methods:
Local management using the Console port on the switch and the
menus interface. See “Local Management Connection” on page 19.
Remote management using a web browser and the web browser
interface. See “Remote Management Connection” on page 19.
The chapters in Section I of this guide explain how to manage the switch
from a local management session using the menu interface. The chapters
in Section II explain how to manage the device from a remote session
using the web browser interface. Both interfaces allow you to configure all
of a switch’s parameters.

Local
Management
Connection
Remote
Management
Connection
To establish a local management connection with an AT-FS750/16 or
AT-FS750/24 Fast Ethernet Switch, you must connect a terminal or a PC
with a terminal emulator program to the console port on the front of the
switch using the management cable which is 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 device is
located.
Note
For instructions on how to start a local management session, refer to
“Starting a Local Management Session” on page 26.
A switch does not need an Internet Protocol (IP) address for local
management. 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.
The AT-S80 management software has a web browser interface for
managing the AT-FS750/16 and AT-FS750/24 switches remotely from any
management station on your network that has a web browser application.
The switch must have an IP address in order for you to manage it remotely
with a web browser. You can assign the IP address manually or activate
the DHCP client so the switch automatically obtains its IP configuration
from a DHCP server on the network. The initial assignment of an IP
address or the activation of the DHCP client software must be performed
through a local management session of the switch.
For instructions on how to start a remote management session, refer to
“Establishing a Remote Connection to Use the Web Browser Interface” on
page 214.
Note
A remote management station must be a member of the switch’s
Default VLAN for you to use it to manage the unit. The switch
processes remote management packets only when they are
received on an untagged port of the Default VLAN.
Note
The AT-S80 Management Software does not support remote
management with the Telnet application protocol.
19
Chapter 1: Overview
Remote SNMP Management
You can also remotely configure the switch using a Simple Network
Management (SNMP) application such as AT-View. This management
method requires an understanding of Management Information Base
(MIB) objects.
Note
You must assign an IP address to the switch for remote SNMP
management. For background information, see “Configuring the IP
Address, Subnet Mask, and Gateway Address” on page 32.
20
Management Access Level
The AT-S80 Management Software has one management access level:
manager. When you log in as a manager, you can view and configure all of
the switch’s operating parameters. You log in as a manager by entering
the appropriate username and password when you start an AT-S80
management session. The default username is “manager” and the default
password is “friend.”

Chapter 1: Overview
Ports 17 and 18 on the AT-FS750/16 Switch and Ports 25 and 26 on the AT-FS750/24 Switch
Ports 17 and 18 on the AT-FS750/16 switch and ports 25 and 26 on the
AT-FS750/24 switch are dual ports. Each has one 10/100/1000Base-T
twisted pair port and one transceiver slot for an optional SFP transceiver.
Note the following when configuring these dual ports:
By default, the twisted pair port of a dual port is the active port.
An optional SFP port is activated when it establishes a link with an end
node, at which point the affiliated twisted pair port changes to the
redundant state.
A twisted pair port and its affiliated optional SFP port share the same
configuration settings, including port settings and VLAN assignments.
When an SFP port establishes a link with an end node, it operates with
the same settings as the twisted pair port.

The following prompt is displayed:
Enter new mode for port n (a/h/H/f/F/T)>
5. Enter the letter that corresponds to the desired speed and duplex
mode setting for the port. The port settings are:
a - Auto: The port uses Auto-Negotiation to set its speed and duplex
mode. This is the default setting for all ports.
h - 10 Mbps, half-duplex
f - 10 Mbps, full-duplex
H - 100 Mbps, half-duplex
F - 100 Mbps, full-duplex
T - 1000 Mbps, full-duplex (uplink ports only)
When selecting a setting, note the following:
The selections are case sensitive. For example, you must enter a
lowercase letter “a” to select Auto-Negotiation.
When a twisted pair port on the switch is set to Auto-Negotiation,
the default setting, the end node should also be set to AutoNegotiation to prevent a duplex mode mismatch. A switch port
using Auto-Negotiation defaults to half-duplex if it detects that the
end node is not using Auto-Negotiation. This can result in a
Section I: Using the Menus Interface 57
Chapter 4: Port Configuration
mismatch if the end node is operating at a fixed duplex mode of
full-duplex. To avoid this problem, disable Auto-Negotiation on the
port and set the port’s speed and duplex mode manually when
connecting an end node with a fixed duplex mode of full-duplex to
a switch port.
For 1000 Mbps operation on an uplink 10/100/1000Base-T twisted
pair uplink port, Allied Telesis recommends using AutoNegotiation. Setting the speed and duplex mode manually to 1000
Mbps full duplex is not recommended.
The only valid setting for an optional SFP port is Auto-Negotiation.
6. Type Q to select Quit to previous menu and save your changes.
58 Section I: Using the Menus Interface
Changing the Flow Control Setting
Flow control applies to ports operating in full-duplex mode. A switch port
uses flow control to control the flow of ingress packets from its end node. A
port using flow control issues a special frame, referred to as a PAUSE
frame, as specified in the IEEE 802.3x standard, to stop the transmission
of data from an end node. When a port needs to stop an end node from
transmitting data, it issues this frame. The frame instructs the end node to
cease transmission. The port continues to issue PAUSE frames until it is
ready again to receive data from the end node.
To change the flow control setting on a port, perform the following
procedure:
1. From the Main Menu, type B to select Basic Configuration.
The Basic Switch Configuration Menu is shown in Figure 4 on page 32
2. From the Basic Switch Configuration Menu, type P to select Port
Configuration.

Chapter 5: Port Trunking
Port Trunking Overview
Port trunking is an economical way for you to increase the bandwidth
between two Ethernet switches. A port trunk is 2 to 8 ports that have been
grouped together to function as one logical path. A port trunk increases
the bandwidth between switches and is useful in situations where a single
physical data link between switches is insufficient to handle the traffic
load.
A port trunk always sends packets from a particular source to a particular
destination over the same link within the trunk. A single link is designated
for flooding broadcasts and packets of unknown destination.
Port Trunking
Guidelines
Observe the following guidelines when creating a port trunk:
A port trunk can consist of up to 8 ports.
The switch can support up to 7 trunks.
A port can belong to only one trunk at a time.
The ports of a trunk must be of the same medium type. For example,
they can be all twisted pair ports or all fiber optic ports.
The speed, duplex mode, and flow control settings must be the same
on all the ports in a trunk.
The ports of a trunk must be members of the same VLAN.
The ports of a trunk do not have to be consecutive.
When you cable a trunk, the order of the connection should be
maintained on both nodes. The lowest numbered port in a trunk on the
switch should be connected to the lowest numbered port of the trunk
on the other device, the next lowest numbered port on the switch
should be connected to the next lowest numbered port on the other
device, and so on.
For example, assume that you are connecting a trunk between two
AT-FS750 switches. On the first AT-FS750 switch, select ports 1
through 4 for a trunk. On the second AT-FS750 switch, select ports 6
through 9. To maintain the order of the port connections, connect port
1 on the first AT-FS750 switch to port 6 on the second AT-FS750
switch, port 2 to port 7, and so on.
To avoid compatibility problems, Allied Telesis recommends that both
switches connected by a trunk are AT-FS750 switches. A port trunk
between an AT-FS750 switch and another switch model might result in
undesirable trunk behavior.
62 Section I: Using the Menus Interface
AT-S80 Management Software User’s Guide
Trunk 7 is reserved for the uplink ports 17 and 18 on the AT-FS750/16
switch and ports 25 and 26 on the AT-FS750/24 switch. You cannot
add or remove ports from this trunk. To use the uplink ports as a port
trunk, activate Trunk 7 as explained in “Enabling and Disabling a Port
Trunk” on page 69.

IGMP Snooping
This chapter explains how to activate and configure the Internet Group
Management Protocol (IGMP) snooping feature on the switch. Sections in
the chapter include:
“IGMP Snooping Overview” on page 72
“Configuring IGMP Snooping” on page 74
Section I: Using the Menus Interface 71
Chapter 6: IGMP Snooping
IGMP Snooping Overview
IGMP enables IPv4 routers to create lists of nodes that are members of
multicast groups. (A multicast group is a group of end nodes that want to
receive multicast packets from a multicast application.) The router creates
a multicast membership list by periodically sending out queries to the local
area networks connected to its ports.
A node that wants to become a member of a multicast group responds to a
query by sending a report. A report indicates an end node’s desire to
become a member of a multicast group. Nodes that join a multicast group
are referred to as host nodes. After becoming a member of a multicast
group, a host node must continue to periodically issue reports to remain a
member.
After the router has received a report from a host node, it notes the
multicast group that the host node wants to join and the port on the router
where the node is located. Any multicast packets belonging to that
multicast group are then forwarded by the router out the port. If a particular
port on the router has no nodes that want to be members of multicast
groups, the router does not send multicast packets out the port. This
improves network performance by restricting multicast packets only to
router ports where host nodes are located.
There are three versions of IGMP — versions 1, 2, and 3. One of the
differences between the versions is how a host node signals that it no
longer wants to be a member of a multicast group. In version 1, it stops
sending reports. If a router does not receive a report from a host node
after a predefined length of time, referred to as a time-out value, it
assumes that the host node no longer wants to receive multicast frames,
and removes it from the membership list of the multicast group.
In version 2, a host node exits from a multicast group by sending a leave
request. After receiving a leave request from a host node, the router
removes the node from appropriate membership list. The router also stops
sending multicast packets from the port to which the node is connected if it
determines there are no further host nodes on the port.
Version 3 adds the ability of host nodes to join or leave specific sources in
a multicast group.
The IGMP snooping feature supports IGMP versions 1 and 2. The ATFS750 switches monitor the flow of queries from a router as well as report
leave messages from host nodes to build its own multicast membership
lists. Both switches use the lists to forward multicast packets to switch
ports where there are host nodes who are members of multicast groups.
This improves switch performance and network security by restricting the
flow of multicast packets only to those switch ports connected to host
nodes.
72 Section I: Using the Menus Interface
AT-S80 Management Software User’s Guide
Without IGMP snooping, a switch needs to flood multicast packets from all
of its ports, except the port on which it received the packet. Such flooding
of packets can negatively impact network performance.
The AT-FS750 switches maintain a list of multicast groups through an
adjustable timeout value, which controls how frequently it expects to see
reports from end nodes that want to remain members of multicast groups,
and by processing leave requests.
Note
By default, IGMP snooping is disabled on the switch.

Chapter 7: Static Multicast Address
Static Multicast Address Overview
There are 4 ways to populate the database of a MAC address table:
Static unicast addresses which can only be assigned to one port
Static multicast addresses which can be assigned to multiple ports
Broadcast addresses which are broadcast to all of the ports on a
switch
Dynamically learned MAC addresses
If you want the MAC address table to act as a forwarding database,
configure it with static multicast MAC addresses.
The Static Multicast Address feature allows you to assign an IP address to
more than one host. This feature is used for video streaming when you
also enable IGMP snooping. For more information about configuring IGMP
snooping, see Chapter 6, “IGMP Snooping” on page 71.
For the static multicast address, the MAC addresses are prelearned. This
means that you can assign a MAC address before you create a physical
connection to a host.

connect a network analyzer to the port where the traffic is copied and
monitor it without impacting performance or speed.
The port whose traffic you want to mirror is called the mirrored port. The
port where the traffic will be copied to is called the mirroring port.
Observe the following guidelines when using this feature:
You can mirror only one port at a time.
The mirrored and mirroring ports must be on the same switch.
This feature copies both the ingress and egress traffic of the mirrored
port.
The mirroring port cannot be used for normal Ethernet switching.

Chapter 10: Virtual LANs
VLAN Overview
A VLAN is a group of ports on an Ethernet switch that form a logical
Ethernet segment. The ports of a VLAN form an independent traffic
domain where the traffic generated by the nodes of a VLAN remains within
the VLAN.
With VLANs, you can segment your network through the switch’s AT-S80
management software and so be able to group nodes with related
functions into their own separate, logical LAN segments. These VLAN
groupings can be based on similar data needs or security requirements.
For example, you could create separate VLANs for the different
departments in your company, such as one for Sales and another for
Accounting.
VLANs offer several important benefits:
Improved network performance
Network performance often suffers as networks grow in size and as
data traffic increases. The more nodes on each LAN segment vying for
bandwidth, the greater the likelihood overall network performance
decreases.
VLANs improve network perform because VLAN traffic stays within the
VLAN. The nodes of a VLAN receive traffic only from nodes of the
same VLAN. This reduces the need for nodes to handle traffic not
destined for them. It also frees up bandwidth within all the logical
workgroups.
In addition, because each VLAN constitutes a separate broadcast
domain, broadcast traffic remains within the VLAN. This too can
improve overall network performance.
Increased security
Because data traffic generated by a node in a VLAN is restricted only
to the other nodes of the same VLAN, you can use VLANs to control
the flow of packets in your network and prevent packets from flowing to
unauthorized end nodes.
Simplified network management
In addition, VLANs can simplify network management. Before the
advent of VLANs, physical changes to the network often had to been
made at the switches in the wiring closets. For example, if an
employee changed departments, changing the employee’s LAN
segment assignment might require a change to the wiring at the
switches.
98 Section I: Using the Menus Interface
AT-S80 Management Software User’s Guide
But with VLANS, you can change the LAN segment assignment of an
end node connected to the switch through the switch’s AT-S80
management software. You can change the VLAN memberships
through the management software without moving the workstations
physically, or changing group memberships by moving cables from one
switch port to another.
In addition, a virtual LAN can span more than one switch. This means
that the end nodes of a VLAN do not need to be connected to the
same switch and so are not restricted to being in the same physical
location.
The AT-FS750 switches support the following types of VLANs you can
create yourself:
Port-based VLANs
Tagged VLANs
These VLANs are described in the following sections.
Section I: Using the Menus Interface 99
Chapter 10: Virtual LANs
Port-based VLAN Overview
As explained in “VLAN Overview” on page 98, a VLAN consists of a group
of ports on an Ethernet switch that form an independent traffic domain.
Traffic generated by the end nodes of a VLAN remains within the VLAN
and does not cross over to the end nodes of other VLANs unless there is
an interconnection device, such as a router or Layer 3 switch.
A port-based VLAN is a group of ports on an AT-FS750 Fast Ethernet
Switch that form a logical Ethernet segment.
A port-based VLAN can have as many or as few ports as needed. The
VLAN can consist of all the ports on an Ethernet switch, or just a few ports.
The parts of a port-based VLAN in the AT-S80 management software are:
VLAN name
Group ID
VLAN Name To create a port-based VLAN, you must give it a name. The name should
reflect the function of the network devices that are be members of the
VLAN. Examples include Sales, Production, and Engineering.
Group ID Each VLAN in a network must have a unique number assigned to it. This
number is called the Group ID. This number uniquely identifies a VLAN in
the switch.
Each port of a port-based VLAN can belong to as many VLANs as
needed. Therefore, traffic can be forwarded to the members of the groups
to which the port is assigned. For example, port 1 and port 2 are members
of group 1 and ports 1 and 3 are members of group 2. In this case, traffic
from port 1 is forwarded to ports 2 and 3, traffic from port 2 is forwarded
only to port 1, and traffic from port 3 is forwarded only to port 1.
General Rules for
Creating a Port-
based VLAN
Below is a summary of the general rules to observe when creating a portbased VLAN.
Each port-based VLAN must be assigned a name.
Each port-based VLAN must be assigned to one or more Group IDs. If
a particular VLAN spans multiples switches, each part of the VLAN on
the different switches should be assigned the same Group ID.
A port-based VLAN that spans multiple switches requires a port on
each switch where the VLAN is located to function as an
interconnection between the switches.
The AT-FS750/16 and AT-FS750/24 switches can support up to 256
port-based VLANs.
