Configuring a Layer 2 Interface as a Private-VLAN Host Port

Beginning in privileged EXEC mode, follow these steps to configure a Layer 2 interface as a
private-VLAN host port and to associate it with primary and secondary VLANs:
Isolated and community VLANs are both secondary VLANs.
Note
Command
Step 1 configure terminal
Step 2 interface interface-id
Step 3 switchport mode private-vlan host
Step 4
switchport private-vlan host-association
primary_vlan_id secondary_vlan_id
Step 5 end
Step 6 show interfaces [interface-id] switchport
Step 7 copy running-config startup config
This example shows how to configure an interface as a private-VLAN host port, associate it with a
private-VLAN pair, and verify the configuration:
Switch# configure terminal
Switch(config)# interface gigabitethernet0/22
Switch(config-if)# switchport mode private-vlan host
Switch(config-if)# switchport private-vlan host-association 20 25
Switch(config-if)# end
Switch# show interfaces gigabitethernet0/22 switchport
