How to create VLAN on a Netgear GS724TP
A Virtual Local Area Network, Virtual LAN or VLAN is a group of hosts with a common set of requirements, which communicate as if they were attached to the same broadcast domain regardless of their physical location. A VLAN has the same attributes a physical LAN, but it allows for end stations to be grouped together even if not on the same network switch. VLANs allow network traffic to flow more efficiently within subgroups. VLANs use software to reduce amount of time it takes for network changes, additions and moves to be implemented.
Setting up VLANs
- A VLAN does not have a minimum number of port
- VLANs work at Layer2 (OSI)
- VLAN can be created per unit, device or logical connection or a combination
- Broadcast and Multicast traffic is transmitted only in the VLAN in which traffic is generated
- To allow traffic between VLAN, a device working at protocol level (layer 3) is required.
VLAN tagging provides a method of transferring VLAN information between VLAN groups. VLAN tagging attaches a 4-byte tag to packet headers. The VLAN tag indicates which VLAN the packets belong to. VLAN tags are attached to the VLAN by the end station or network device. VLAN tags also contain VLAN network priority information.
How to setup a VLAN
- Assign a static IP in the range of the switch. The default IP of the switch is 192.168.0.239
- Login to the device using the URL http://192.168.0.239
- Browse to Switch – > VLAN Properties
- Add the VLANs to be created by specifying the VLAN ID and the VLAN Name.
- VLAN1 is the default VLAN and cannot be modified. This VLAN also manages the switch
- Apply the settings.
- Browse to VLAN Membership
- From the VLAN ID list – select the VLAN you want to add ports to (by default all the ports are members of VLAN1)
- Click on the Static box correspondent to the port until this shows a U (Untagged) symbol.
- Repeat these steps for all the ports that are required to be member of the VLAN
- Click Apply when completed.
- Browse to Interface PVID settings and set the PVID for each port assigned to the new VLAN to VLAN ID (for VLAN2 PVID = 2, for VLAN3 PVID=3…)
- Ensure one port is part of all the VLANs as this would work as the trunk port.
- Click on Apply to finalise the changes.
Verify the VLAN is working
- Configure two PCs with unique IP address (within the same range) and same subnet mask
- Patch each PC in one of the ports that are members of the VLAN you wish to test
- You should now be able to ping each machine from the other
- Re-patch one of the machines to a port on a different VLAN
- You should not be able to ping such machine from the others.
