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 ports 3 and 4 as uplinks and ports 5 and 6 as
downlinks.
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.
To avoid these problems, you can configure this switch with
protocol-based VLANs that divide the physical network into logical
VLAN groups for each required protocol. When a frame is received at a
