1. What is VLAN?
VLAN (Virtual Local Area Network) 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 is a broadcast domain created by switches. This means the VLAN is configured on switches, layer 3 switches. Note that some of the switches don’t support VLAN.
2. When do I need a VLAN?
It is important to point out that you don’t have to configure a VLAN until your network gets so large and has so much traffic that you need one.
You need to consider using VLAN in any of following situations:
Step1. You have more than 200 devices on your LAN
Step2. You have a lot of broadcast on your LAN
Step3. Groups of users need more security or are being slowed down by too many broadcasts
Step4. Groups of users need to be on the same broadcast domain because they are running the same applications. An example would be a company that has a lot of VoIP phones connect to an IPPBX. The administrator of the network might like to separate the VoIP from the network and configure VLAN for IP phones and PCs.
3. How do I create a VLAN?
You need to do this on your switch.
4. What do I need to configure on MyPBX?
Please follow the steps below to set up VLAN on MyPBX.
Step1. Create VLANs on your switch
Step2. Allocate a VLAN ID and IP address for MyPBX
Step3. Configure VLAN settings page on MyPBX (optional). System Network Preferences VLAN Settings
Note: Not all kinds of VLAN needs configuration on MyPBX. It depends on what kind of VLAN you create on your switch.

Note: MyPBX is a VLAN client, not a VLAN server.
