1 INTRODUCTION
This section describes the features of the 12-port Switch, as well as
giving some background information about Ethernet and Fast
Ethernet switching technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of
desktop computing applications are fueling the need for high
performance networks. A number of high-speed LAN technologies
have been proposed to provide greater bandwidth and improve
client/server response times. Among them, Fast Ethernet, or
100Base-T, provides a non-disruptive, smooth evolution from the
current 10Base-T technology. The non-disruptive and smooth
evolution nature, and the dominating potential market base,
virtually guarantee cost effective and high performance Fast
Ethernet solutions in the years to come.
100Mbps Fast Ethernet is a new standard specified by the IEEE
802.3 LAN committee. It is an extension of the 10Mbps Ethernet
standard with the ability to transmit and receive data at 100Mbps,
while maintaining the CSMA/CD Ethernet protocol. Since the
100Mbps Fast Ethernet is compatible with all other 10Mbps
Ethernet environments, it provides a straightforward upgrade and
takes advantage of the company’s existing investment in
hardware, software, and personnel training.
Introduction 1
10/100 Fast Ethernet Switch User’s Guide
Switching Technology
Another approach to pushing beyond the limits of Ethernet
technology is the development of switching technology. A switch
bridge's Ethernet packets at the MAC address level of the
Ethernet protocol transmitting among connected Ethernet or Fast
Ethernet LAN segments.
Switching is a cost-effective way of increasing the total network
capacity available to users on a local area network. A switch
increases capacity and decreases network loading by making it
possible for a local area network to be divided into different
segments which don’t compete with each other for network
transmission capacity, giving a decreased load on each.
The switch acts as a high-speed selective bridge between the
individual segments. The switch, without interfering with any
other segments automatically forwards traffic that needs to go
from one segment to another. This allows the total network
capacity to be multiplied, while still maintaining the same network
cabling and adapter cards.
For Fast Ethernet networks, a switch is an effective way of
eliminating problems of chaining hubs beyond the two-repeater
limit.” A switch can be used to split parts of the network into
different collision domains, making it possible to expand your Fast
Ethernet network beyond the 205-meter network diameter limit
for 100BASE-TX networks. Switches supporting both traditional
10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal for
bridging between existing 10Mbps networks and new 100Mbps
networks.
Switching LAN technology is a marked improvement over the
previous generation of network bridges, which were characterized
by higher latencies. Routers have also been used to segment local
area networks, but the cost of a router and the setup and
2 Introduction
10/100 Fast Ethernet Switch User’s Guide
maintenance required make routers relatively impractical. Today
switches are an ideal solution to most kinds of local area network
congestion problems.
Features
The Switch is designed for easy installation and high performance
in an environment where traffic on the network and the number of
users increase continuously.
The Switch with its rack size is specifically designed for network
workgroups. The Switch provides immediate access to a rapidly
growing network through a wide range of user-reliable functions.
The Switch is ideal for deployment with multiple high-speed
servers for shared bandwidth 10Mbps or 100Mbps workgroups. In
200Mbps full-duplex mode, any port can provide workstations with
a congestion-free data pipe for simultaneous access to the server.
The Switch is expandable by cascading two or more switches
together. As all ports support 200Mbps full duplex, the Switch can
be cascaded from any port and to any number of switches.
The Switch is a perfect choice for site planning to upgrade to Fast
Ethernet in the future. Ethernet workgroups can connect to the
Switch now, and change adapters and hubs anytime later without
needing to change the Switch or reconfigure the network.
The Switch combines dynamic memory allocation with store-andforward switching to ensure that the buffer is effectively allocated
for each port, while controlling the data flow between the transmit
and receive nodes to guarantee against all possible packet loss.
Other key features are:

NOTE: To perform a factory reset, turn the device off. Power on
the device again and the factory settings should now be in
effect.
Parameters in this screen are described in the following table.
Field Description
PID Displays the number of the currently selected port.
EN Displays the RX/TX status of the selected port, Enable or
Disable.
Link Displays the current status of the link between the selected port
and the connected node. This can be Up or Down.
AN Displays the Auto Negotiation function status of the selected
port. This can be On or Off.
Spd Displays the Port Speed associated with duplex mode. This
can be 10(10M/HDX), 20(10M/FCX), 100(100M/HDX), or 200
(100M/FDX).
Dupx Displays the Duplex mode of the selected port. This can be Full
or Half Duplex mode. Full duplex transmissions effectively
double your bandwidth by carrying out transmission and receipt
of packets at the same time.
Each port in the 12-port NWay switch can be set for half duplex
or full duplex mode. You need to set the Duplex mode through
the Dip switch at the rear of the device. To set a port in fullduplex mode, slide the corresponding switch up. To set it in
half-duplex mode, slide the corresponding switch down.
To make full duplex mode work properly, make sure both ends
of the link are configured to full duplex mode.
FCtrl Displays Flow Control status of the selected port. This can be
On or Off.
Spd U Displays User Set Port Speed. This can be 10 or 100Mbps.

Figure 13, Set port ENABLE/DISABLE
Because the following four functions have the similar screens that
let you specify. Displayed here is the screen for E: set port
ENABLE/DISABLE.
E: Set port ENABLE/DISABLE. This is the operating status of
the port. Use this screen to enable or disable the selected port.
A disabled port does not transmit any packets to the connected
segment, nor forward any received packets.
A: Set the AN function ENABLE/DISABLE. This is the Auto
Negotiation status for the port. Use this screen to enable or
disable the Auto Negotiation function for the port.
R: Set the data rate 10/100. This is the current connection speed
specified for the port. Use this screen to set the speed of a port.
Port speed can be either 10Mbps or 100Mbps.
F: Set flow control ENABLE/DISABLE. This is the Flow Control
status for the port. Use this screen to enable or disable Flow

Control for the port. Flow Control minimizes dropped packets by
sending out collision signals when the
port receiving buffer is full. Press 0 to disable flow control and
press 1 to set data rate as 100Mbps.
NOTE: Flow control is only available in half-duplex mode. In full-
duplex mode, flow control is not available. The port status &
setting list indicates only the setting configured for flow
control rather than the status of flow control.
Port Counter
With the Port Counter, you can do the following:
C: Monitor statistics related to the traffic status of each port.
The screen below is the Port 2 counter.

Parameters in this screen are described in the following table.
Field Description
TX Packet Count The number of packets that have been
transmitted successfully by the selected port.
Packets are from 64-1518 bytes, including the
CRC.
RX Byte Count The size, in bytes, of all packets received and
forwarded successfully by the selected port.
RX Packet Count The number of packets that have been received
successfully on the selected port.
RX Broadcast
PKT
RX Multicast
PKT
The number of broadcast packets that are
received.
The number of multicast packets that are
received.
RX Reject Count The number of discarded packets that are
received on the selected port. These frames
are discarded at the receiving port because of
frame filtering.
RX Drop Event
Count
The number of lost packets received on the
selected port. Lost packets result from the lack
of internal receive buffer space.
FCS Error Count The number of packets with cyclic redundancy
check (CRC) errors that are received on the
selected port.
Alignment Error
PKT
The number of alignment errors received on the
selected port. An alignment error occurs when
a received packet is not an integral number of
bytes.
Under Size PKT The number of packets received that were well
formed but less than 64 bytes long.
Over Size PKT The number of packets received that were well
formed but greater than 1,518 bytes long.
