pvlan

This command enables or configures a private VLAN. Use the no form to disable the private VLAN.

Syntax

pvlan [up-link interface-listdown-link interface-list] no pvlan

•up-link – Specifies an uplink interface.

•down-link – Specifies a downlink interface.

Default Setting

No private VLANs are defined.

Command Mode

Global Configuration

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 12 as the uplink and ports 5-8 as the downlinks.

Console(config)#pvlan
