Chapter 10 Configuring Private VLANs
Configuring Private VLANs
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.
• 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.
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
