To implement the above requirements, you can configure 802.1Q VLAN on both Switches.ġ) Create VLAN 2.

It is required that the two groups cannot communicate with each other, but both of them can access the internet. Specify the PVID of port 2 as 2 and the PVID of port 3 as 3.Īs the following figure shows, a company has two groups which connect to two switches.

Click Apply.Ĭhoose the menu VLAN > 802.1Q VLAN PVID Setting to load the following page. Add port 1 and port 3 to VLAN 3 as untagged ports. In the 802.1Q VLAN Setting section, enter 3 in the VLAN (1-4094) field. Add port 1 and port 2 to VLAN 2 as untagged ports. In the 802.1Q VLAN Setting section, enter 2 in the VLAN (1-4094) field. Note: Only after you enable the 802.1Q VLAN feature, you can add or modify VLANs. Leave port 1-3 as untagged ports in VLAN 1 (By default, all ports belong to VLAN 1.)Įxampled with TL-SG105E, the following section shows how to configure 802.1Q VLAN on the switch using web GUI and using configuration utility.Ĭhoose the menu VLAN > 802.1Q VLAN to load the following page. Add port 1, 3 to VLAN 3.ģ) Keep port 1, 2, 3 in VLAN 1. Add port 1, 2 to VLAN 2.Ģ) Create VLAN 3. To meet the above requirements, you can configure 802.1Q VLAN on the switch.ġ) Create VLAN 2. It is required that the computers in the two groups cannot communicate with each other, but both of them can access the internet via the router. Here are two configuration examples for 802.1Q VLAN.Īs the following figure shows, the switch connects to two different groups. A LAN can be divided into several VLANs logically, and only the hosts in a same VLAN can communicate with each other. VLAN (Virtual Local Area Network) is a technology that can solve broadcasting issues.
