Configuring Private VLANs
Private VLANs provide port-based security and isolation between ports
within the assigned VLAN. Data traffic on downlink ports can only be
forwarded to, and from, uplink ports. (Note that private VLANs and
normal VLANs can exist simultaneously within the same switch.)
Enabling Private VLANs
Use the Private VLAN Status page to enable/disable the Private VLAN
function.
Web – Click Private VLAN, Private VLAN Status. Select Enable or
Disable from the scroll-down box, and click Apply.
CLI – This example enables private VLANs.
