4. Network Configuration

This section provides you a few samples of network topology in
which SMC-EZ1026DT V.2 Switch ( UTP/MT-RJ/VF-45, Intelligent )
is used.

The Switch provides versatile configuration options for the network.
It is ideally suited as a workgroup or segment Switch in a network; it
has the flexibility to provide Switched 10Mbps to the desktop or
shared hubs, aggregate traffic from workgroup Switches, or provide
dedicated 100Mbps or 1000Mbps ( Gigabit ) to servers with
bandwidth-intensive applications. And because all Fast Ethernet
ports auto-negotiate for operation at 100 Mbps the Switch is
perfectly suited to an evolving network environment where demand
for network speed is increasing.

4.1 Collapsed Backbone Application

For small network where rapid growth can be expected in the near
future, this Switch is an ideal solution supporting backbone
connectivity.

The Switch can be used as a standalone Switch for a group of heavy
traffic users. Switching is brought to the desktop either through a
single end-station per Switch port or through a multi-port Switch.
A 1000 Mbps server is connected to the Switch, providing end
stations high-speed accessibility to its applications. This
configuration provides dedicated 100 Mbps connections to the
network center and to the server.
When the network needs expansion, you can simply connect the
Switch to any IEEE 802.3 (Ethernet), IEEE 802.3u (Fast Ethernet )
and 802.3ab (Gigabit Ethernet ) compliant Switch utilizing the Auto
MDI/MDIX function. This Switch can also cooperate with a wide
range of networking devices (e.g., firewall routers and printer
servers) added to the network.

21

SMC-EZ1026DT V.2

Figure 4-1. Collapsed Backbone Application

4.2 Departmental Bridge

For enterprise networks where large data broadcasts are constantly
processed, this Switch is an ideal solution for department users to
connect to the corporate backbone. The SMC-EZ1026DT V.2 Switch
used as segment Switch can alleviate user contention for bandwidth
and eliminate server and network bottlenecks. All ports can connect
to high-speed department servers that need high bandwidth. This
Switch provides parallel communications within it’s Gigabit port,
which can run up to 2000 Mbps at Full-duplex.

The Switch makes key servers available to more users by allowing
multiple conversations to occur concurrently, thereby significantly
expanding overall network throughput. Moreover, this Switch eases
supervision and maintenance by allowing network manager
centralize multiple servers in a single location.

22

SMC-EZ1026DT V.2

Figure 4-2: Departmental Bridge Application

NOTE: Full-duplex operation only applies to point-to-point access (for

example, when attaching the Switch to a workstation, server, or another

Switch). When connecting to hubs, use a standard cascaded connection

set for half-duplex operation.

4.3 High Performance Switched Workgroup

This Switch is also a good solution for connecting two workgroups,
supporting the throughput, for example, of 800Mbps. This
application is useful for power groups that need high bandwidth.

The most common LAN implementations use a combination of
standard switches, bridges and routers. The bridges and routers
quickly become bottlenecks, reducing overall network throughput.
Switching to higher-speed LANs such as FDDI or ATM is not a good
choice for most people.
However, such broadband equipment is still extremely expensive
and hard to maintain. Besides, you have to replace all existing
Ethernet cable and adapter cards, restructure your network, and
implement more expensive administration procedures.

23

SMC-EZ1026DT V.2

The Switch can provide the same bandwidth of FDDI and ATM at
much lower costs. In addition, all current adapters and network
devices can still be used. The Switching cross-domain connection is
better than bridge and router because users can retain LAN
structure in which any node can freely communicate with any other
node.

Figure 4-3: High Performance Switched Workgroup Application

4.4. VLAN Application

Port-based VLAN Workgroup

You can group the Switch ports into broadcast domains by assigning
them to the same VLAN to increase network capacity and
performance. With network segmentation, each Switch port
connects to a segment that is a single broadcast domain. Packets
received in one VLAN can only be forwarded within that VLAN.

VLAN allows the grouping of end stations logically, based not on
physical location but on business policies such as job function or
department. Members of a group can be dispersed throughout a
facility - they do not have to be connected in close physical
locations.

24

SMC-EZ1026DT V.2

Hence, group members can coordinate their data communication
requirements regardless of the actual working locations; and the
logical network can extend to any point you want it to. Moreover,
VLAN groups can be modified at any time to add, move or change
users without any re-cabling.

Figure 4-4: VLAN Workgroup Application

Shared Server

The Switch compliant to the IEEE802.1Q tagging VLAN standard
allows ports to exist in multiple VLANs for shared resources, such as
servers, printers, and Switch-to-Switch connections. It is also
possible to have resources exist in multiple VLANs on one Switch as
shown in the following figure.

25

SMC-EZ1026DT V.2

Figure 4-5: Shared Server

In this example, stations on different VLANs share resources. As a
result, VLAN 1 and VLAN 2 can access VLAN 3 for printing. The
broadcasts from ports configured in VLAN3 can be seen by all VLAN
port members of VLAN3.
