Configuring the Switch

The DES-1226G has a Web GUI interface for smart switch configuration. The Switch can be configured through the Web browser. A network

administrator can manage, control, and monitor the Switch from the local LAN. This section indicates how to configure the Switch to enable its

smart functions including:

²

Port Setting (Speed/Disable, Duplex mode, Flow Control, and Port base QoS)

²

Virtual LAN Group setting (VLAN)

²

Trunking

²

Port Mirroring

²

Static MAC

²

System Setting

²

Device status

Login

Before you configure this device, note that when the Web-Smart Switch is configured through an Ethernet connection, the manager PC must be

set on same the

IP network

. For example, when the default network address of the default IP address of the Web Smart Switch is

192.168.0.1

,

then the manager PC should be set at 192.168.0.x (where x is a number between 2 and 254), and the default subnet mask is 255.255.255.0.

Open an Internet Explorer 5.0 or above Web browser.

Enter the IP address

(the factory-default IP address setting) in the address location.

Figure 7.

Through the Web Management Utility, you do not need to remember the IP Address; select the device shown in the Monitor List of the Web

Management Utility to settle the device on the Web browser.

When the following dialog page appears, enter the default password

"admin"

and press Login to enter the main configuration window.

Figure 8.

After entering the password, the main page appears and the screen will display the device status.

Figure 9. Device Status

Setup Menu

When the main page appears, find the

Setup menu

in the left side of the screen (Figure 15). Click on the setup item that you want to configure.

There are eleven options:

Port Settings, VLAN Settings, Trunk Setting, Mirror Setting, Static MAC, Device Status, Statistic, System Settings, Trap

Setting, Password Setting, Backup Setting, and Reset Setting

as shown in the Main Menu screen.

Configuring Setup Setting

There are four items, including

Port Settings, VLAN Settings, Trunk Settings, Mirror Settings and Static MAC

in Setup menu.

Port Settings

The Port Settings menu page (Figure 11) displays each port’s status. Click on the ID parameter to set each port’s

Speed, Flow Control, QoS priority,

and Link Status

. When you need to renew the posted information, press the “Refresh” button.

The

Link Status

in the screen will show the connection speed and duplex mode. This dialog box will display

down

when the port is disconnected.

Figure 11. Port Configuration

Note:

1.

Be sure

to reset the Gigabit port when transferring the media type ( Fiber to Copper or Copper to Fiber ).

2.

The priority of Gigabit Fiber port is higher than Copper.

To change the port setting, click on the ID parameter to enter the selected port to configure its Speed/Disable, Flow control, and QoS settings.

Figure 12.

Speed/Disable:

This setting has six modes—

100M Full

,

100M Half

,

10M Full

,

10M Half

,

Auto

,

and Disable

—for speed or port disable selections.

Flow Control:

This setting determines whether or not the Switch will be handling flow control. Set

FlowCtrl

to

Enable

to avoid data transfer overflow. It is set to

Disable

when there is either no flow control or other hardware/software management.

When the port is set to

forced mode

, the flow control will automatically be set to

Disable.

QoS:

In some ports that need to have a high priority to manage the data transfer, QoS should be changed. Set the port’s QoS to high to determine that the

port will always transfer their data first.

VLAN Settings (Virtual Local Area Network)

Group individual ports into a small “Virtual” network of their own to be independent of the other ports. To add a VLAN group, press the “Add Group”

button. The new VLAN configuration window will appear, and you can fill in the description in order to describe this VLAN Group, check on the port to

be a member to this VLAN Group, and press the

“Apply”

button to execute the setting.

Figure 13. VLAN Group Settings

Once you want to modify the VLAN Group, check on the ID parameter; the ID VLAN configuration window will appear.

Figure 14. VLAN Settings

Trunk Setting

The Trunk function enables you to cascade two devices with a double times bandwidth (up to 4000Mbps in full-duplex mode).

There are two trunking groups for selection; you can select either or both groups for trunking.

Figure 15. Trunk Settings

Be sure that the selected trunk setting port must connect to the device with a same VLAN group.

Mirror Setting

Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of a network

switch to another port where the packet can be studied. It enables the manager to keep close track of switch performance and alter it if necessary.

Configuring the port mirroring by assigning a source port from which to copy all packets and a sniffer port where those packets will be sent.

The selection of the sniffer mode is as follows:

TX (transmit) mode:

This mode will duplicate the data transmitted from the source port and forward it to the sniffer port.

RX (receive) mode:

This mode will duplicate the data sent to the source and forward it to the sniffer port.

Both (transmit and receive) mode:

This mode will duplicate both data transmitted from and data sent to the source port, then it will forward it to the

sniffer port.
