6.9.2 VLAN Settings (Virtual Local Area Network)
A VLAN is a group of ports which act as a small “virtual” network of their own, independent of the other
ports. This means that the broadcast domain is restricted to the computers within a VLAN, and
computers connected to different VLANs are unable to communicate with each other. The VLAN
Setting page displays the current VLANs on the switch (Figure 17).
Figure 17: VLAN Setting Page
To create a new VLAN group, click the “Add Group” button to open the new VLAN configuration
window (Figure 18). Enter a description for the VLAN, and select the ports to include in the VLAN.
Click “Apply” button to save the new VLAN.
To modify a VLAN, click on its ID number. In the new window, make the required modifications and
click “Apply”.
To delete a VLAN, click “Delete Group” to open a window which allows you to select a VLAN to
delete.
