This example shows how to configure VLAN 20 as a primary VLAN, VLAN 501 as an isolated VLAN,
and VLANs 502 and 503 as community VLANs, to associate them in a private VLAN, and to verify the
configuration:
Switch# configure terminal
Switch(config)# vlan 20
Switch(config-vlan)# private-vlan primary
Switch(config-vlan)# exit
Switch(config)# vlan 501
Switch(config-vlan)# private-vlan isolated
Switch(config-vlan)# exit
Switch(config)# vlan 502
Switch(config-vlan)# private-vlan community
Switch(config-vlan)# exit
Switch(config)# vlan 503
Switch(config-vlan)# private-vlan community
Switch(config-vlan)# exit
Switch(config)# vlan 20
Switch(config-vlan)# private-vlan association 501-503
Switch(config-vlan)# end
Switch(config)# show vlan private vlan

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

The secondary_vlan_list parameter cannot contain spaces. It can contain multiple comma-separated
items. Each item can be a single private-VLAN ID or a hyphenated range of private-VLAN IDs.
The secondary_vlan_list parameter can contain multiple community VLAN IDs but only one
isolated VLAN ID.
Enter a secondary_vlan_list, or use the add keyword with a secondary_vlan_list to associate
secondary VLANs with a primary VLAN.
Use the remove keyword with a secondary_vlan_list to clear the association between secondary
VLANs and a primary VLAN.
The command does not take effect until you exit VLAN configuration mode.
