5.4.7 VLAN Configuration
A Virtual LAN ( VLAN) is a logical network grouping that limits the broadcast domain. It allows you to
isolate network traffic so only members of the VLAN receive traffic from the same VLAN members.
Basically, creating a VLAN from WGSD-1020 is logically equivalent of reconnecting a group of net-
work device to another Layer 2 Switch. However, the entire network device is still plug into the same
Switch physically.
WGSD-1020 support port-based(refer to section 5.4.7.1) and protocol-based VLAN (refer to section
5.4.7.2) in web management page. In the default configuration VLAN is enable and all ports belong to
the default VLAN ( VID=1).
5.4.7.1 Port-based VLANs ( IEEE 802.1Q VLAN)
Port-based Tagging rule VLAN is an IEEE 802.1Q standard. Therefore, it’s possible to create a VLAN
across devices from different Switch venders. IEEE 802.1Q VLAN use a technique to insert a ” Tag”
into the Ethernet frames. Tag contains a VLAN identifier (VID) that indicates the VLAN numbers.
Note: You can disable/enable VLAN function and choose VLAN operation Mode from Switch Set-
tings.

Create a new VLAN group and add tagged member ports procedure:
1. From the main menu , click administrator →VLAN configuration. The screen in Figure 5-27 appears.
2. Click “Add” to create a new VLAN group.
3. Type a name for the new VLAN and VLAN ID (between 2- 4094). The default VLAN of each port 1.
4. From the available ports box, select ports to add to the Switch and click “Add”
5. Click “Apply” to take effect.
You can click” Help” button; the following screen in Figure 5-28 appears.
