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 fastethernet0/22
Switch(config-if)# no shutdown
Switch(config-if)# switchport mode private-vlan host
Switch(config-if)# switchport private-vlan host-association 20 501
Switch(config-if)# end
Switch# show interfaces fastethernet0/22 switchport
Name: Fa0/22
Switchport: Enabled
Administrative Mode: private-vlan host
Operational Mode: private-vlan host
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: native
Negotiation of Trunking: Off
Access Mode VLAN: 1 (default)
Trunking Native Mode VLAN: 1 (default)
Administrative Native VLAN tagging: enabled
Administrative private-vlan host-association: 20 501
Administrative private-vlan mapping: none
Administrative private-vlan trunk native VLAN: none
Administrative private-vlan trunk Native VLAN tagging: enabled

Step 3
no shutdown Enable the port, if necessary. By default, UNIs and ENIs
are disabled, and NNIs are enabled.
Step 4
switchport mode private-vlan host Configure the Layer 2 port as a private-VLAN host port.
Step 5
switchport private-vlan host-association
primary_vlan_id secondary_vlan_id
Associate the Layer 2 port with a private VLAN.
Step 6
end Return to privileged EXEC mode.
Step 7
show interfaces [interface-id] switchport Verify the configuration.
Step 8
copy running-config startup config (Optional) Save your entries in the switch startup
