This example shows how to configure VLAN 303 as a community VLAN and verify the configuration:

Router# configure terminal

Router(config)# vlan 303

Associating Secondary VLANs with a Primary VLAN

To associate secondary VLANs with a primary VLAN, perform this task:

When you associate secondary VLANs with a primary VLAN, note the following syntax information:

• 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.

• 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.

Command Purpose

Step 1 Router(config)# vlan primary_vlan_ID Enters VLAN configuration submode for the primary

VLAN.

Step 2 Router(config-vlan)# private-vlan association

{secondary_vlan_list | add secondary_vlan_list |

remove secondary_vlan_list}

Associates the secondary VLANs with the primary

VLAN.

Router(config-vlan)# no private-vlan association Clears all secondary VLAN associations.

Step 3 Router(config-vlan)# end Exits VLAN configuration mode.

Step 4 Router# show vlan private-vlan [type] Verifies the configuration.
