Chapter 5 Basic Configuration for Compex GSC2024WM

16

The main page will be displayed as shown. You may scroll down to view
the status of different functi ons, such as connectivity, speed of individual
ports, port trunking, VLANs, duplex mode, etc.

5.2 Changing system settings

IP address configuration is for confi guring IP address of the managem ent
board in the switch. It is likely that sev eral VLANs are on the single switch ,
and each VLAN can be regarded as an independent network, so their
network addresses may be different. In order that each end-station
connected to switch port can access the managem ent system, multiple
IP addresses are needed for the management board.

Simply go to Misc Operation in the menu
and select System Setting as shown in the
figure at the right hand side.

Chapter 5 Basic Configuration for Compex GSC2024WM

17

Next, you may set a switch name and
location for your Compex
GSC2024WM for easy identification.

The default IP address for Compex
GSC2024WM is 192.168.100.128. To
change it, simply enter the new IP
address, subnet mask and the IP
address of the gateway, and click on

Apply to update the changes.

5.3 Configure individual port setting

To set the duplex mode, flow control and
port priority, simply go to Port Configuration in
the main menu. The overall port settings will
appear as shown in the figure on the right.

Simply click on one of the port IDs and its settings will appear.

Speed:

Chapter 5 Basic Configuration for Compex GSC2024WM

18

This option allows you to work in either forced or auto mode. When
Compex GSC2024WM is set to forced mode (10M/100M), the auto-MDI X
function will be disabled.

This means that you will be requi red to use the appropriate E thernet RJ45
cable to connect your devices: a straight-through MDI Ethernet RJ45
cable to connect your PC to Compex GSC2024WM; or a crossover MDIX
Ethernet RJ45 cable to connect your Compex GSC2024WM to your hub.

On the other hand, if you set the speed to Auto, you will can use any
Ethernet RJ45 cable with any devices since the auto-MDIX function will
have been activated.

Flow Control:

This feature reports the flow control setti ngs of the port. Enabling the fl ow
control function limits the amount of traffic which crosses the switch.

QoS:

Quality of Service (QoS) refers to the c apabili ty of a network to provi de a
better service to selected ports in the switch. A port with priority set to
High will have its transmitted packets serviced fi rst at the receiving port.

The example above ill ustrates
that Port 24 is set to high
priority; and Port 1 and 2 are
in normal priority. When Port 2
and 24 send packets to Port 1
at the same time, the pack et
from Port 24 will be serviced
first by Port 1 as a higher
priority was given to P ort 24.

Chapter 6 Advanced Configuration

19

Chapter 6 Advanced Configuration

Compex GSC2024WM allows you to separate the network into small segments
for easy management. This not only improves the network performance, but
also provides security between workgrou ps. Besides that, bandwidth incremen t
can also be done between cascaded switches.

This chapter will cover the following:

• Setting Virtual Local Area Network (VLAN)

• Expanding the limitation on bandwidth for cascaded switches

6.1 Network Scenario

In a company, two LAN segments are implemented on switch, S1. A
printer shared between both Accounts and Sales departments is
physically located at the Sales Department. To allow the users in
Accounts department to access the printer, you can simply create the
printer as a member of both the Sales and the Accounts Departments
using VLAN.

Figure 6.1a VLAN in a network

Chapter 6 Advanced Configuration

20

6.1.1 Virtual LAN Configuration

In a VLAN, all end-stations communicate with each other as if
they were in the same local LAN although they may be not o n
the same physical network segmen t. However, all data packets
in a VLAN are constrained to the VLAN so end stations in
different VLANs cannot communicate with each other directly.
Compex GSC2024WM supports port-based VLAN, i.e. the VLAN is
specified by selecting a group of ports bel onging to the VLAN.

Now, we are going to illustrate how to set up a VLAN with
Compex GSC2024WM.

From the main menu of the web-based interface of Compex
GSC2024WM,

1. Click on VLAN configuration. As you can see from the figure
shown below, all ports are configured in VLAN 01 by default.

2. Select ID 01 to edit the members in the VLAN ID 01.

3. Give a description for your VLAN ID 01. Select which ports
should belong to this VLAN, I n our example, we set Port 3 to
Port 9 as the members of ID 01. Notice that port 9, which is
connected to the printer, is also set in this VLAN ID.

Chapter 6 Advanced Configuration

21

4. Click on Apply and proceed to confi g ure VLAN 02.

5. Give a description, such as Sales Dept, to identify your VLAN.

6. Select which ports should belong to this VLAN. In our
example, we set Port 9 to Port 13 as the members of VLAN ID

02. Note that we also need to include Port 9 in this VLAN.

7. Click on Apply. Now, you can see the VLANs which have
been configured. Notice that port 9 (connected to the
shared printer) is a member of both VLANs.

Chapter 6 Advanced Configuration

22

6.1.2 Expand the limitation on bandwidth

We define Port Trunking as the abili ty to group a set of ports into
a single logical link. This is an inexpensive method to increase
throughput between switches. The port trunk acts as single link
between switches. It does not create a loop even though the
ports are physically connected.

From the figure shown below, S1 is connected to S 2 through Ports
1 and 2; S2 is connected to S3 via Ports 9,10,11 and 12. We need
to increase the bandwidth of these thr ee-cascaded switches in
order to allow all members to have faster access to the file server.
This can be done by using Port Trunking Configuration.

Chapter 6 Advanced Configuration

23

We explain how to configure port trunking using the example
illustrated above.

For S1

1. Go to the main menu of the web-based interface of
Compex GSC2024WM, select Trunk Configuration.

2. Select Port 01 and 02 as members of Trunk ID 01.

3. Click on Apply to update the chang es.

For S2

1. Select Port 01 and 02 as members of Trunk ID 01; and Port 09,
10, 11, 12 as members of Trunk ID 02.

2. Click on Apply to update the chang es.

For S3

1. Select Port 09, 10, 11, and 12 as members of Trunk 02.

2. Click on Apply to update the chang es.

Once the trunking config uration for the three switches has bee n
done, you will notice that the speed of transmission will be much
faster than before.

Chapter 7 Monitoring Your Network

24

Chapter 7 Monitor your Network

This chapter will cover the following:

• Duplicating copies of incoming packets and forward to a monitoring port

• Monitoring Trap

• Viewing the statuses of indi vidual functions

7.1 Mirror Control

This function allows you to set up a ‘mirror’ port of any specified port/s,
such that you can monitor the incoming and/or outgoing traffic at the
monitored port/s wi thout i nterrupti ng the cli ent/s on the moni tored port/s .
A network administrator can use port mirroring as a diagnostic tool or
debugging feature.

From the figure, Port 23 is configured as the sni ffer port and port 1 is set as
the source port. This means that using the PC attached to Port 23 , the
network administrator i s able to keep a close track of the da ta traffic at
Port 1.

Once we set Port 1 (for example) as the source port, a duplicate copy of
each packet that is being sent and/or received via Port 1 will also be
forwarded to Port 23.

1. Select Mirror Configuration from the main page.

2. Choose which packets to monitor by selecting either Rx (Receive),
Tx (Transmit) or Both (Received and transmit) from the pull down
menu.

3. Choose Port 23 as the Sniffer Port. This is the port to which the
monitored packets will be forwarded.
