Configuring Private VLANs
A Private VLAN allows modification of the default VLAN to provide
port-based security and isolation between ports within the V LAN. Data
traffic on downlink ports can only be forwarded to, and from, uplink ports.
Private VLANs and normal VLANs can exist simultaneously within the
same switch. Both individual ports and port trunks can be configure d as
downlink or uplink interfaces.
Enabling Private VLANs
Use the Private VLAN Status page to enable/disable the Private VLAN
function.
Web Inte rfac e
Click Private VLAN/Private VLAN Status, then select Enabled/Disabled
to enable or disable the Private VLAN function.
Command Line Interface
This example enables private VLANs.
Configuring Uplink and Downlink Ports
Use the Private VLAN Status and Private VLAN Status Link pages to
enable/disable the Private VLAN function and to configure port groups as
downlink or uplink ports.
When one port in a group is configured as a downlink or uplink port, all
other ports in that group are also configured as down link or uplink ports.
The Web and Command Line Interface however, will only display the
explicitly configured port as a downlink or uplink port.
