Configuring Private VLANs
Configuring a Layer 2 Interface as a Private-VLAN Promiscuous Port
Beginning in privileged EXEC mode, follow these steps to configure a Layer 2 interface as a
private-VLAN promiscuous port and map it to primary and secondary VLANs:
Note Isolated and community VLANs are both secondary VLANs.
When you configure a Layer 2 interface as a private-VLAN promiscuous port, 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.
• Enter a secondary_vlan_list, or use the add keyword with a secondary_vlan_list to map the
secondary VLANs to the private-VLAN promiscuous port.
• Use the remove keyword with a secondary_vlan_list to clear the mapping between secondary
VLANs and the private-VLAN promiscuous port.
This example shows how to configure an interface as a private-VLAN promiscuous port and map it to a
private VLAN. The interface is a member of primary VLAN 20 and secondary VLANs 501 to 503 are
mapped to it.
Switch# configure terminal
Switch(config)# interface gigabitethernet1/0/2
Switch(config-if)# switchport mode private-vlan promiscuous
Switch(config-if)# switchport private-vlan mapping 20 add 501-503
Switch(config-if)# end
Use the show vlan private-vlan or the show interface status privileged EXEC command to display
primary and secondary VLANs and private-VLAN ports on the switch.
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Enter interface configuration mode for the Layer 2
interface to be configured.
Step 3 switchport mode private-vlan promiscuous Configure the Layer 2 port as a private-VLAN
promiscuous port.
Step 4 switchport private-vlan mapping primary_vlan_id
{add | remove} secondary_vlan_list Map the private-VLAN promiscuous port to a primary
VLAN and to selected secondary VLANs.
Step 5 end Return to privileged EXEC mode.
Step 6 show interfaces [interface-id] switchport Verify the configuration.
Step 7 copy running-config startup config (Optional) Save your entries in the switch startup
configuration file.
