Configuring A Layer 2 Interface As A Private Vlan Promiscuous Port - Cisco 6500 Series Software Configuration Manual

Chapter 10 Configuring Private VLANs
This example shows how to configure interface FastEthernet 5/1 as a private VLAN host port and verify
the configuration:
Router# configure terminal
Router(config)# interface fastethernet 5/1
Router(config-if)# switchport mode private-vlan host
Router(config-if)# switchport private-vlan host-association 202 303
Router(config-if)# end
Router# show interfaces fastethernet 5/1 switchport
Name: Fa5/1
Switchport: Enabled
Administrative Mode: private-vlan host
Operational Mode: down
Administrative Trunking Encapsulation: negotiate
Negotiation of Trunking: On
Access Mode VLAN: 1 (default)
Trunking Native Mode VLAN: 1 (default)
Administrative private-vlan host-association: 202 (VLAN0202) 303 (VLAN0303)
Administrative private-vlan mapping: none
Operational private-vlan: none
Trunking VLANs Enabled: ALL
Pruning VLANs Enabled: 2-1001
Capture Mode Disabled

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:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# switchport
Step 3
Router(config-if)# switchport mode private-vlan
{host | promiscuous}
Router(config-if)# no switchport mode
private-vlan
Step 4
Router(config-if)# switchport private-vlan
mapping primary_vlan_ID {secondary_vlan_list |
add secondary_vlan_list | remove
secondary_vlan_list}
Router(config-if)# no switchport private-vlan
mapping
Step 5
Router(config-if)# end
Step 6
Router# show interfaces [type
switchport
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet

Purpose
1
Selects the LAN interface to configure.
slot/port
Configures the LAN interface for Layer 2 switching:
Configures the Layer 2 port as a private VLAN
promiscuous port.
Clears the private VLAN port configuration.
Maps the private VLAN promiscuous port to a primary
VLAN and to selected secondary VLANs.
Clears all mapping between the private VLAN
promiscuous port and the primary VLAN and any
secondary VLANs.
Exits configuration mode.
1
Verifies the configuration.
