Configuring Private VLANs

Command Usage

A Private VLAN allows modification of the default VLAN to provide 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.

Example

This example globally enables private vlan, and then configures ports 13 and 14 as uplink ports, and ports 1-8 as downlink ports.

Console(config)#pvlan

Console(config)#Console(config)#pvlan up-link ethernet 1/13-14 down-link ethernet 1/1-8

Console(config)#end

Console#

show pvlan
