Port-based mode
Tag-based mode
By above settings, there are four private networks will be created and computers attached
with each of LAN ports or SSIDs which are able to obtain a private IP address from each
DHCP server (LAN1/LAN2/LAN3/LAN4). However, the traffics of the LAN port or SSID that
are NOT being grouped in the same VLAN are unable to forward to each other. The benefit
of Port-based is able to extend the wired ports by installing a cheaper dumb switch as
many as you need, but Tag-based offers you a flexible and well-managed network. The
networks are isolated, secured and reduce the broadcasting storm effectively in each of
networks with VLAN.
