Chapter 36 Configuring Private VLANs
How to Configure PVLANs
• Use the remove keyword with a secondary_vlan_list to clear the mapping between secondary
VLANs and the PVLAN promiscuous port.
This example shows how to configure interface FastEthernet 5/2 as a PVLAN promiscuous port, map it
to a PVLAN, and verify the configuration:
Switch# configure terminal
Switch(config)# interface fastethernet 5/2
Switch(config-if)# switchport mode private-vlan promiscuous
Switch(config-if)# switchport private-vlan mapping 200 2
Switch(config-if)# end
Switch#show interfaces fastethernet 5/2 switchport

Configuring a Layer 2 Interface as a PVLAN Host Port
To configure a Layer 2 interface as a PVLAN host port, perform this task:
Command Purpose
Step 1
Switch# configure terminal
Enters configuration mode.
Step 2
Switch(config)# interface {fastethernet |
gigabitethernet | tengigabitethernet}
slot / port
Specifies the LAN port to configure.
Step 3
Switch(config-if)# switchport mode private-vlan
{host | promiscuous} | trunk
Configures a Layer 2 interface as a PVLAN host port.
Step 4
Switch(config-if)# [no] switchport private-vlan
host-association
primary_vlan_ID
secondary_vlan_ID
Associates the Layer 2 interface with a PVLAN.
You can use the no keyword to delete all associations
from the primary VLAN.
Step 5
Switch(config-if)# end
Exits configuration mode.
Step 6
Switch# show interfaces {fastethernet |
gigabitethernet | tengigabitethernet}
slot / port
switchport
Verifies the configuration.
