Private VLANs provide port-based security and isolation between ports within the
assigned VLAN. This section describes commands used to configure private VlANs.

private VLAN.

• up-link – Specifies an uplink interface.
• down-link – Specifies a downlink interface.

Command Usage
• A private VLAN provides port-based security and isolation between ports
within the VLAN. Data traffic on the downlink ports can only be forwarded to,
and from, the uplink port.
• Private VLANs and normal VLANs can exist simultaneously within the same
switch.
• Entering the pvlan command without any parameters enables the private
VLAN. Entering no pvlan disables the private VLAN.
Example
This example enables the private VLAN, and then sets port 24 as the uplink and
ports 1-4 as the downlinks.
