A switch such as the VigorSwitch P would then be connected to Vigor Port 2 and the corresponding port on the switch would also be configured to the same VLAN tags. The "Permit untagged device in P1 to access router" box is ticked which means that a PC can also be directly connected to the Vigor port 1 without needing to be configured to be vlan aware and still communicate with the router.
The actual VLAN setup page therefore looks like this:. Not all networking equipment supports tagged VLANs, so to accommodate those, you can have tagged data and untagged data running on the same network, perhaps physically isolated by port-based VLANs, or your switch can remove the VLAN tag before forwarding the data onto the connected device.
A feature of most tag-capable Ethernet switches is that they can add, remove, change or forward VLAN tags.

Port-based VLANs groups virtual local area network by port.
Devices that are connected to this port will belong to the same broadcast domain that is because all other ports are configured with a similar VLAN number.
The challenge of this type of network is to know which ports are appropriate to each VLAN. You can determine it by checking the configuration information. This type of VLAN processes traffic based on a protocol that can be used to define filtering criteria for tags, which are untagged packets. It works in multi-protocol environments. This method is not practical in a predominately IP based network. The configurations of tables are shared among all device ports.
