Chapter 1
Getting Started
This chapter provided information and instructions on how to start a
local management session using the AT-S67 or AT-S68 management
software. This chapter contains the following sections:
‰ Overview on page 12
‰ Starting a Local Management Session on page 13
11
Getting Started
Overview
The AT-S67 and AT-S68 management software offers limited
management features that simplifies the task of creating or expanding
an Ethernet or Fast Ethernet network. The features, functions, and
interface are the same for both the AT-S67 and AT-S68 management
software. However, the AT-S67 is the management software for use with
the AT-FS7016 Smart Switch and the AT-S68 is the management
software for use with the AT-FS7024 Smart Switch.
The AT-S67 and AT-S68 management software comes pre-installed on
the switches with default settings for all the operating parameters. To
change or adjust the operating parameters, you must access the switch’s
management software.
You can create a local management session with an AT-FS7016 or
AT-FS7024 Smart Switch by connecting a terminal or PC with a terminal
emulator program to the RS-232 Terminal Port using a straight-through
RS-232 cable. This type of management session is referred to as a “local”
because you must be physically close to the switch where the switch is
located.
Once the session is started, a Main Menu is displayed so that 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.
For instructions on starting a local management session, refer to
Starting a Local Management Session on page 13.
12
AT-S67 and AT-S68 User’s Guide
Starting a Local Management Session
The AT-FS7016 and AT-FS7024 Smart Switches features a RS-232
Terminal Port. You can access the HyperTerminal interface through the
RS-232 port on the front of the switch.
Note
A switch does not need an IP address to be managed from a local
management session. You can start a session at any time on either
an AT-FS7016 or AT-FS7024 Smart Switch in your network. Running
a local management session does not interfere with the flow of
Ethernet traffic through the unit.
Starting a Local
Management
Session
To start a local management session, perform the following procedure:
1. Connect one end of a straight-through RS-232 cable with a DB-9
connector to the RS-232 Terminal Port on the switch. Refer to Figure

3. Enter the number of the port you want to configure and press
<Enter>. The Port Configuration Menu in Figure 4 is displayed.
Figure 4 Port Configuration Menu
4. Change the port parameters as desired. The parameters are described
below:
1- TX/RX
This option allows you to manually disable or enable a port on the
switch so that it can no longer receive or send frames. You may
want to disable a port if a problem occurs with the end-node or
the cable connected to the port. Once the problem has been
fixed, you can enable the port again to resume normal network
operation. You can also disable an unused port to secure if from
unauthorized connections. Enable port is the default setting.
2 - Flow Control
When the port is operating in full-duplex mode, it will uses a
special pause packet to stop the end-node from sending frames.
The pause packet notifies the end-node to stop transmitting for a
specific period of time. The flow control allows the port to
decrease the frequency in which it is sending packets to the
receiving end-node, if packets are being sent to fast.
When the port is operating in half-duplex mode and flow control
is enabled and if the RX buffer becomes full, the switch will
produce a jamming signal. This jamming signal sends a collision
to the end-node notifying the end-node to stop sending packets
until the jamming signal is cleared.
19
Port Configuration
Possible Flow Control settings are Enable and Disabled. The
default setting is Enabled.
3 - AutoNegotiation
You use this parameter to configure the port for Auto-negotiation
or to manually set the port’s speed and duplex mode. If you select
Enabled, which is the default, the switch will set both the speed
and duplex mode for the port automatically. If you select Disable,
two additional parameters are displayed in the Port Configuration
Menu:
4 - Speed ....... 10 MB
5 - Duplex ......Half Duplex
You use these two parameters to set the port’s speed and duplex
mode.
The possible setting for 4 - Speed are:
10 - indicates the port is operating at 10 Mbps.
100 - indicates the port is operating at 100 Mbps
The possible settings for 5 - Duplex are half-duplex and fullduplex.
5. Once you have set the port parameters, type S to select Save Port
Configuration.
You will be returned to the Port Menu.
The port configurations have been set. To configure additional ports
repeat this procedure.

AT-S67 and AT-S68 User’s Guide
Displaying Port Status
To display the status of the ports on an AT-FS7000 Series Switch, perform
the following procedure:
1. From the Main Menu, type 1 to select Port Menu. The Port Menu
shown in Figure 3 on page 18 is displayed.
2. From the Port Menu, type 4 to select Port Status. The Port Status
window in Figure 5 is displayed.

range from 1 to 16. For an AT-FS7024 port numbers will range from 1 to
24.
Link
The status of the link between the port and the end-node connected to
the port. Possible settings are Up and Down. Up indicates that a valid
link exists between the port and the end-node. Down indicates that the
port and the end-node have not established a valid link.
21
Port Configuration
Neg
The status of Auto-negotiation on the port. Possible settings are Auto
and Manual. Auto indicates that the port is using Auto-negotiation to set
operating speed and duplex mode. Manual indicates that the operating
speed and duplex mode have been set manually.
Spd
The operating speed of the port. Possible values are 10; indicating the
port is operating at 10 Mbps, and 100; indicating the port is operating at
100 Mbps.
Dplx
The duplex mode of the port. Possible settings are half-duplex and fullduplex. Half-duplex indicates that the port is operating at half-duplex
mode. Full-duplex indicates that the port is operating at full-duplex
mode.
Flow
The flow control setting for the port. Flow control allows the port to
decrease the frequency in which it is sending frames to the receiving
end-node, if frames are being sent to fast. It will also send flow control
frames to a transmitting end-node to request that the port slow its
speed of transmission. Possible settings are Enabled (ON) or Disabled
(NONE).
State
The current operating status of the port. Possible values are Enabled and
Disabled. Enabled indicates the port is sending and receiving Ethernet
frames. Disabled indicates the port has been manually disabled.

Port Trunking
This chapter provides information and procedures for creating a port
trunk. This chapter contains the following sections:
‰ Overview on page 24

Port Trunking
Overview
Port trunking is an economical way for you to increase the bandwidth
between two Ethernet switches. A port trunk is 2, 3, or 4 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.
Figure 6 illustrates a port trunk of four data links between two
AT-FS7016 switches.

Guidelines
Observe the following guidelines when creating a port trunk:
‰ A port trunk can consist of 2, 3, or 4 ports.
‰ 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 for all the ports in a trunk.
‰ The ports of a trunk must be members of the same VLAN. A port
trunk cannot consist of ports from different VLANs.
24
AT-S67 and AT-S68 User’s Guide
‰ Trunking ports cannot span across port groups. Refer to Figure 7
and Figure 8 for port groupings.

‰ When cabling 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-FS7024 switches. On the first AT-FS7024 switch you had
chosen ports 12, 13, 14, and 15 for a trunk. On the second
AT-FS7024 switch you had chosen ports 21, 22, 23, and 24. To
maintain the order of the port connections, you would connect
port 12 on the first AT-FS7024 switch to port 21 on the second
AT-FS7024 switch, port 13 to port 22, and so on.
25
Port Trunking
‰ Do not connect the cables to the trunk port on the switches until
after you have configured the trunk with the management
software. Connecting the cables before configuring the software
will create a loop in you network topology. Data loops can result
in broadcast storms and poor network performance.

Port Mirroring
Overview
The port mirroring feature allows you to monitor the traffic being
received and transmitted on one or more ports on a switch. This is done
by having traffic copied to another port on the switch. You can connect a
network analyzer to the port where the traffic is being copied and
monitor the traffic on the other ports without impacting network
performance or speed.
Observe the following guidelines when creating a port mirror:
‰ You can monitor from one to up to 23 ports, depending on your
model. However, the more ports you mirror, the less likely the
mirroring port will be able to handle all the traffic. For example, if
you mirror the traffic of six heavily active ports, the mirror port is
likely to drop packets. This means that the mirror port will not
provide an accurate mirror of the traffic of the other six ports.
‰ The ports to be mirrored and the mirroring port must be located
on the same switch.
‰ The ports to be mirrored and the mirroring port must be
operating at the same speed. For example, you cannot use a 10
Mbps port to mirror traffic on a 100 Mbps port.
The AT-S67 and AT-S68 management software also features an
advanced port mirroring. For information and instructions, refer to
Configuring Advanced Mirroring on page 41.

Virtual LANs
VLAN Features
A Virtual Local Area Network (VLAN) is a logical grouping of devices on
different physical LAN segments that allows users to communicate as if
they were physically connected to a single LAN, independent of the
physical configuration of the network.
With VLAN switch management software, you can segment your
network and group end-nodes with related functions into their own
separate, logical LAN segments. For example, the marketing personnel
in you company may be spread through-out a building. Assigning
marketing to a single VLAN allows marketing personnel to share
resources and bandwidth as if they were connected to the same
segment. The resources of other departments can be visible to the
marketing VLAN members, accessible, or accessible only to specified
individuals.
A few benefits of a VLAN architecture are described in the following
sections.
Increased
Performance
In traditional Layer 2 switched networks, broadcast packets are sent to
each and every individual port. VLANs address the limitations of
standard switch segmentation by containing broadcast as well as endnode-to end-node traffic.
Grouping users into logical networks limits broadcast traffic to users
performing similar functions or users within individual workgroups. High
traffic, the danger of broadcast storms, router latency, and data
collisions are significantly reduced, and the efficiency of the entire
network is improved.
Improved
Manageability
VLANs provide a fundamental improvement in the design,
administrations, and management of LANs. Before VLANs, physical
changes to a network were made at the switch in the wiring closet.
For example, if an employee transferred to a new department, changing
that employee’s LAN segment assignment often required a physical
wiring change at the switch.
As a software-base solution, VLANs eliminate the restriction of existing
network design and cabling infrastructure and allow the centralized
configuration of switches located in many different locations. VLAN
memberships are changed quickly and efficiently from the management
console rather than in a wiring closet.
46
AT-S67 and AT-S68 User’s Guide
Increased
Security
VLANs provide additional security not available in a shared media
network environment. Because a switched network only delivers frames
to intended recipients, and only broadcast frames to other members of
the VLAN, a network administrator can segment users requiring access
to sensitive information into separate VLANs from the rest of the general
user community.
Since data traffic generated by an end-node in a VLAN is restricted only
to the other end-nodes of the same VLAN, VLANs can be used to control
the flow of data in your network. It can also prevent data from flowing to
unauthorized end-nodes.
47
Virtual LANs
Overview of Port-based VLANs
Port-based VLANs are the simplest and most common form of a VLAN. In
a port-based VLAN configuration, each port of the switch is assigned to a
specific VLAN. For example, you can designate port 1, 2, and 3 as part of
the engineering VLAN and ports 5, 6, and 7 as part of the marketing
VLAN.
A port-based VLAN can have as many or as little ports as needed. The
VLAN can consist of all the ports on the AT-FS7016 or AT-FS7024 Smart
Switch, or just a few ports.
Ports in a port-based VLAN are referred to as “untagged ports” and the
frames received on the ports as “untagged frames”. The term
“untagged” is based on that fact that the frames received on a port will
not contain any information that indicates VLAN membership, and that
VLAN membership will be determined only by the port’s PVID.
Port VLAN
Identifier
Each port in a port-based VLAN must have a Port VLAN Identifier (PVID).
The switch associates a frame to a port-based VLAN by the PVID
assigned to the port on which the frame is received and forwards the
frame only to those ports with the same PVID. Consequently, all the
ports of a port-based VLAN must had the same PVID.
Some switches and switch management programs require that you
assign the PVID value for each port manually. However, the AT-S67 and
AT-S68 management software performs this task automatically. The
software automatically assigns a PVID to a port, making it identical to the
VID of the VLAN to which the port is a member.
Special VLAN
Configuration
Feature
The AT-FS7016 and AT-FS7024 Smart Switches provide an enhanced
port-based VLAN feature, which allows a port to be a member of more
than one port-based VLAN. This feature allows you to configure a single
uplink port (for example, to a router) on every VLAN for the purpose of
connecting to a remote location without compromising the basic
security features of a multiple VLAN configuration.
An example of this implementation would be a hotel network which
requires all rooms to be isolated from each other but allow all rooms to
access the internet through a common router.
48
AT-S67 and AT-S68 User’s Guide
Port-based VLAN
Guidelines
The following is a summary of general guidelines to observe when
creating port-based VLANs:
‰ Each port-based VLAN must be assigned a unique VID.
‰ Each port must be assigned a PVID. This value is assigned
automatically by the AT-S67 and AT-S68 management software.
The value is the same for all ports in a port-based VLAN and is
identical to the VLAN’s VID, except when using the special VLAN
configuration feature.
‰ If there are end-nodes in different VLANs that need to
communicate with each other, a router or Layer 3 switch is
required to interconnect the VLANs. In this case, each VLAN must
have it’s own port connection to the router. The special VLAN
configuration feature will not facilitate inter-VLAN
communication.

Quality of Service (QoS)
QoS Overview
The AT-FS7000 Series Switches feature QoS based on the IEEE 802.1p
standard. QoS can be important to network environments when there
are time-critical applications, such as voice transmission or video
conferencing, that can be adversely affected by packet transfer delays.
When QoS is enabled, the switch will assign the ingress frames to either
high priority and low priority. The switch determines these priorities
based on the 802.1p tag within the frame. If the frame is untagged the
switch will classify the frame based on the value assigned to the ingress
port.
For tagged frames, you can set the 802.1p frame TCI Threshold which
has a value between 1 and 8. The TCI Threshold will send the tagged
frame into either a high priority queue or low priority queue depending
on the TCI Threshold value. If the value of the frame tag is equal to or less
than the TCI Threshold the frame will be sent to the low priority queue.
For example, if the TCI Threshold is set to 5, incoming frames with a tag
of 6 and above will be sent to the high priority queue. Frames with a tag
of 5 and below will be sent to the low priority queue.
For untagged frames, the port based QoS values that are assigned to
each port determine if the frame is assigned to the high priority queue or
the low priority queue.
You can also set the weights to the high and low priority queues for the
egress of the frames. The priority queue weights have a value between 1
and 15. Weights are designed to allow a set number of outgoing frames
to be delivered from the high priority queue and the low priority queue
based on the high/low ratio. For example, if you have a high priority
queue weight of 15 and low priority queue weight of 1, this means for
every 15 high priority frames sent 1 low priority frame will be sent.
When the QoS is disabled, all tagged and untagged frames are treated
equally and placed in one queue on the switch.

MAC Address Overview
Every hardware device that you connect to your network has an unique
MAC address. A MAC address is assigned to a device by the device’s
manufacturer. For example, every network interface card that you use to
connect your computers to your network has a MAC address assigned to
it by the adapter’s manufacturer.
The AT-FS7000 Series Switch’s MAC address table can contain up to 4
kilobytes. The switch uses the table to store the MAC addresses of the
network end-nodes connected to its ports, along with the port number
on which each address was learned.
The switch learns the MAC addresses of the end-nodes by examining the
source address of each packet received on a port. It adds the address
and port on which the packet was received to the MAC address table if
the address has not already been entered in the table. The result is a
table that contains all the MAC addresses of the devices that are
connected to the switch’s ports and the port numbers where each
address was learned.
When the switch receives a packet, it also examines the destination
address and, by referring to its MAC address table, determines the port
where the destination end-node is connected. It then forwards the
packet to the appropriate port and onto the end-node. This increases
network bandwidth by limiting each frame to the appropriate port when
the intended end-node is located, freeing the other switch ports for
receiving and transmitting data.
If the switch receives a packet with a destination address that is not in
the MAC address table, it floods the packet to all the ports on the switch.
If the ports have been grouped into virtual LANs, the switch floods the
packet only to those ports which belong to the same VLAN as the port
on which the packet was received. This prevents packets from being
forwarded onto inappropriate LAN segments and increases network
security. When the destination end-node responds, the switch add its
MAC address and port number to the table.
If the switch receives a packet with a destination address that is on the
same port on which the packet was received, it discards the packet
without forwarding it on to any port. Since both the source end-node
and the destination end-node for the packet are located on the same
port on the switch, there is no reason for the switch to forward the
packet. This also increases network performance by preventing frames
from being forwarded unnecessarily to other network devices.

AT-S67 and AT-S68 User’s Guide
The type of MAC address described above is referred to as a dynamic
MAC address. Dynamic MAC addresses are addresses that the switch
learns by examining the source MAC addresses of the frames received
on the ports.
Dynamic MAC addresses are not stored indefinitely in the MAC address
table. The switch deletes a dynamic MAC address from the table if it does
not receive any frames from the end-node over a specified period of
time. The switch assumes that the end-node with that MAC address is
not longer active and that its MAC address can be purged from the table.
This prevents the MAC address table from becoming filled with
addresses of end-nodes that are no longer active.
The period of time that switch waits before purging an inactive dynamic
MAC address is called the “aging timer”. This value is adjustable on the
AT-FS7000 Series Switches. The default value is 300 seconds (5 minutes).
For instructions on changing the aging timer, refer to Changing the
MAC Aging Time on page 74.
