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.
