Configuring a VLAN as a Private VLAN
To configure a VLAN as a private VLAN, perform this task:
Command
Step 1
Router(config)# vlan vlan_ID
Step 2
Router(config-vlan)# private-vlan {community |
isolated | primary}
Router(config-vlan)# no private-vlan {community |
isolated | primary}
Step 3
Router(config-vlan)# end
Step 4
Router# show vlan private-vlan [type]
This example shows how to configure VLAN 202 as a primary VLAN and verify the configuration:
Router# configure terminal
Router(config)# vlan 202
Router(config-vlan)# private-vlan primary
Router(config-vlan)# end
Router# show vlan private-vlan

Because the private VLAN port sticky ARP entries do not age out, you must manually remove
private VLAN port ARP entries if a MAC address changes. You can add or remove private VLAN
ARP entries manually as follows:
Router(config)# no arp 11.1.3.30
IP ARP:Deleting Sticky ARP entry 11.1.3.30
Router(config)# arp 11.1.3.30 0000.5403.2356 arpa
IP ARP:Overwriting Sticky ARP entry 11.1.3.30, hw:00d0.bb09.266e by hw:0000.5403.2356
