The tagged VLANs (802.1q) can mark data with a VLAN identifier. This identifier can be
carried through an onward Ethernet switch to specific ports. The specific VLAN clients can
also pick up this identifier as it is just passed to the LAN. You can set the priorities for
LAN-side QoS. You can assign each of VLANs to each of the different IP subnets that the
router may also be operating, to provide even more isolation. The said functionality is
tag-based multi-subnet.

Relative to tag-based VLAN which groups clients with an identifier, port-based VLAN uses
physical ports (P1 ~ P4) to separate the clients into different VLAN group.
Virtual LAN function provides you a very convenient way to manage hosts by grouping them
based on the physical port. The multi-subnet can let a small businesses have much better
isolation for multi-occupancy applications. Go to LAN page and select VLAN. The following
page will appear. Click Enable to invoke VLAN function.
