Configuring the Switch
Configuring Uplink and Downlink Ports
Use the Private VLAN Link Status page to set ports as downlink or uplink ports.
Ports designated as downlink ports can not communicate with any other ports on the
switch except for the uplink ports. Uplink ports can communicate with any other ports
on the switch and with any designated downlink ports.
Web – Click VLAN, Private VLAN, Link Status. Mark the ports that will serve as
uplinks and downlinks for the private VLAN, then click Apply.
CLI – This configures port 3 as an uplink and port 5 and 6 as downlinks.
