Chapter 10 Configuring Private VLANs
Configuring Private VLANs
Configuring a Layer 2 Interface as a Private VLAN Promiscuous Port
To configure a Layer 2 interface as a private VLAN promiscuous port, perform this task:
When you configure a Layer 2 interface as a private VLAN promiscuous port, 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.
• Enter a secondary_vlan_list value or use the add keyword with a secondary_vlan_list value to map
the secondary VLANs to the private VLAN promiscuous port.
• Use the remove keyword with a secondary_vlan_list value to clear the mapping between secondary
VLANs and the private VLAN promiscuous port.
This example shows how to configure interface FastEthernet 5/2 as a private VLAN promiscuous port
and map it to a private VLAN:
Router# configure terminal
Router(config)# interface fastethernet 5/2
Router(config-if)# switchport mode private-vlan promiscuous
Router(config-if)# switchport private-vlan mapping 202 303,440
Router(config-if)# end
Command Purpose
Step 1
Router(config)# interface type
1
slot/port
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet
Selects the LAN interface to configure.
Step 2
Router(config-if)# switchport
Configures the LAN interface for Layer 2 switching:
• You must enter the switchport command once
without any keywords to configure the LAN interface
as a Layer 2 interface before you can enter additional
switchport commands with keywords.
• Required only if you have not entered the switchport
command already for the interface.
Step 3
Router(config-if)# switchport mode private-vlan
{host | promiscuous}
Configures the Layer 2 port as a private VLAN
promiscuous port.
Router(config-if)# no switchport mode
private-vlan
Clears the private VLAN port configuration.
Step 4
Router(config-if)# switchport private-vlan
mapping primary_vlan_ID {secondary_vlan_list |
add secondary_vlan_list | remove
secondary_vlan_list}
Maps the private VLAN promiscuous port to a primary
VLAN and to selected secondary VLANs.
Router(config-if)# no switchport private-vlan
mapping
Clears all mapping between the private VLAN
promiscuous port and the primary VLAN and any
secondary VLANs.
Step 5
Router(config-if)# end
Exits configuration mode.
Step 6
Router# show interfaces [type
1
slot/port]
switchport
Verifies the configuration.
