Chapter 1 Configuring Private VLANs
Configuring Private VLANs
When you associate secondary VLANs with a primary VLAN, note this 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 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.
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

private-VLAN host port and to associate it with primary and secondary VLANs:
Note
Isolated and community VLANs are both secondary VLANs.
Command Purpose
