VLAN CONFIGURATION

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.

Configuring Protocol-Based VLANs

The network devices required to support multiple protocols cannot be easily grouped into a common VLAN. This may require non-standard devices to pass traffic between different VLANs in order to encompass all the devices participating in a specific protocol. This kind of configuration deprives users of the basic benefits of VLANs, including security and easy accessibility.
