Command Purpose
Step 1
Router(config)# interface type
1
slot/port
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet

Router(config-if)# no switchport mode
private-vlan
Clears private VLAN port configuration.
Step 4
Router(config-if)# switchport private-vlan
host-association primary_vlan_ID
secondary_vlan_ID
Associates the Layer 2 port with a private VLAN.
Router(config-if)# no switchport private-vlan
host-association
Clears the association.
