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.
