INTRODUCTION
This chapter describes the features of the 16-Port 10/100Mbps
Fast Ethernet Smart Switch and some background information
about Ethernet/Fast Ethernet and 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.
technologies have been proposed to provide greater bandwidth
and improve client/server response times. Among them,
A
number of high-speed LAN
100BASE-T (Fast Ethernet) provides a non-disruptive, smooth
evolution from the current 10BASE-T technology. The non-
disruptive and smooth evolutionary nature, and the dominant
potential market base, virtually guarantee cost-effective and high
performance Fast Ethernet solutions.
100Mbps Fast Ethernet is a 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
100Mbps Fast Ethernet is compatible with all other 10Mbps
Ethernet environments, it provides a straightforward upgrade and
takes advantage of the existing investment in hardware, software,
and personnel training.

Switching Technology
Another approach to pushing beyond the limits of Ethernet
technology is the development of switching technology. A switch
bridges 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 dividing a
local area network into different segments, which don’t compete
with each other for network transmission capacity.
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. By doing this the total network
capacity is multiplied, while still maintaining the same network
cabling and adapter cards.
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, the setup
and maintenance required make routers relatively impractical.
Today switches are an ideal solution to most kinds of local area
network congestion problems.

VLAN (Virtual Local Area Network)
A VLAN is a group of end-stations that are not constrained by
their physical location and can communicate as if in a common
broadcast domain, a LAN. The primary utility of using VLAN is
to reduce latency and need for routers, using faster switching
instead. Other VLAN features include:
¾
Security
Security is increased with the reduction of opportunity for
eavesdropping on a broadcast network because data will be
switched only to those users within the particular VLAN.
¾
Cost Reduction
VLANs can be used to create multiple broadcast domains, thus
eliminating the need for expensive routers.
Port-based (or port-group) VLAN is the common method of
implementing a VLAN, and is the one implimented in this Switch.
Each Switch port can belong to one or more of up to sixteen
VLANs.

High and Low. The default setting for QoS on all ports is High.
To change the QoS setting, highlight Port and enter the port
number to select the desired port. Set QoS as required to
determine which ports will always transfer their data first.
(4) Link Status
This value is automatically determined by the Switch and can’t
be changed. If there is a valid connection to the Switch through
the indicated port, the Link Status will show the connection speed.
The status will be Down if there is no connection through that
port.

For example, there are five computers (PC1~PC5) connected to
the Switch’s port 1~5. They had been divided into two VLAN
groups: VLAN1 (PC1~PC4) and VLAN2 (PC2~PC5). There is
no way to connect PC1 and PC5, as shown in Figure 15. If PC1
has to connect to PC5, it should with it in the same VLAN.

Using VLAN, the Switch can be divided into many independent
small switches. For example, in Figure 16, the Switch has been
divided into two VLAN groups. Both VLAN groups are
independent and there’s no link between these VLAN groups.
The Switch can be regarded as two smaller switches.
