UPPORT
The switch is designed for Internet access deployment where subscriber end
nodes are connected to an Internet Service Provider network through the
switch. In this application, each port is isolated in its own private VLAN to
provide security for each end user, only the uplink port (Port 1) can
communicate with all other ports. Ports 2-8 cannot communicate with each
other.
The switch ports each have a fixed default VLAN ID, with Port 1 fixed as a VLAN
trunk port. The figure below indicates the VLAN IDs assigned to each switch
port. Note that Port 1 is the uplink port and must be connected to a switch or
router in the service provider network.
