8-Port Gigabit Ethernet Smart Managed Plus Switch Model GS908E
VLAN Overview
Virtual LANs (VLANs) are made up of networked devices that are grouped logically into separate networks.
You can group ports on a switch to create a virtual network made up of the devices connected to the ports.
You can group ports in VLANs using either port-based or 802.1Q criteria:
•
Port-based VLANs. Assign ports to virtual networks. Ports with the same VLAN ID are placed in the
same VLAN. This feature provides an easy way to partition a network into private subnetworks.
•
802.1Q VLANs. Create virtual networks using the IEEE 802.1Q standard. 802.1Q uses a VLAN tagging
system to determine which VLAN an Ethernet frame belongs to. You can configure ports to be a part
of a VLAN.
When a port receives data that is untagged, the data is delivered normally. However, when a port
receives data that is tagged for a VLAN, the data is discarded unless the port is a member of that VLAN.
This technique is useful for communicating more securely with devices outside your local network as
well as receiving data from other ports that are not in the VLAN. To use an 802.1Q VLAN, you must
know the VLAN ID.
Manage Port-Based VLANs
After you activate the port-based VLAN mode (also referred to as the basic VLAN mode), you can add and
manage port-based VLANs.
Activate the Port-Based VLAN Mode
By default, all types of VLANs are disabled on the switch. Before you can add and manage port-based
VLANs, you must activate the port-based VLAN mode. This mode is also referred to as the basic VLAN
mode.
When you activate the port-based VLAN mode, VLAN 1 is added to the switch and all ports (1 through 8)
are members of VLAN 1. This is the default VLAN in the port-based VLAN mode.
To activate the port-based VLAN mode:
1.
Open a web browser from a computer that is connected to the same network as the switch or to the
switch directly through an Ethernet cable.
2.
Enter the IP address that is assigned to the switch.
The login page displays.
3.
Enter the switch password.
The default password is password. The password is case-sensitive.
The HOME page displays.
4.
From the menu at the top of the page, select SWITCHING.
The Quality of Service (QoS) page displays.
5.
From the menu on the left, select VLAN.
The VLAN page displays.
