This example shows how to associate community VLANs 303 through 307 and 309 and isolated VLAN
440 with primary VLAN 202 and verify the configuration:
Router# configure terminal
Router(config)# vlan 202
Router(config-vlan)# private-vlan association 303-307,309,440
Router(config-vlan)# end
Router# show vlan private-vlan

Mapping Secondary VLANs to the Layer 3 VLAN Interface of a Primary VLAN

Isolated and community VLANs are both called secondary VLANs.
Note
To map secondary VLANs to the Layer 3 VLAN interface of a primary VLAN to allow Layer 3 switching
of private VLAN ingress traffic, perform this task:
Command
Step 1
Router(config)# interface vlan primary_vlan_ID
Step 2
Router(config-if)# private-vlan mapping
{secondary_vlan_list | add secondary_vlan_list |
remove secondary_vlan_list}
Router(config-if)# [no] private-vlan mapping
Step 3
Router(config-if)# end
Step 4
Router# show interface private-vlan mapping
OL-11439-03
The secondary_vlan_list parameter can contain 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 submode.
When you exit the VLAN configuration submode, only the last specified configuration takes effect.
