Chapter 10 Configuring Private VLANs

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
When you map secondary VLANs to the Layer 3 VLAN interface of a primary VLAN, note the
following syntax information:

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.
303 community
304 community
305 community
306 community
307 community
309 community
440 isolated
308 community
The private-vlan mapping interface configuration command only affects private VLAN ingress
traffic that is Layer 3 switched.
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.
