Re: PVLAN Promiscuous Trunk on 6500

Hi,

 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
 Purpose

Step 1

Router(config)# *interface*
*type*1<http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/
configuration/guide/pvlans.html#wp1143839>
*slot/port*

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.

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.

*Note *If VLAN locking is enabled, enter the VLAN name instead of the VLAN
number. For more information, see the "VLAN Locking"
section<http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/
configuration/guide/vlans.html#wpxref38450>.

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<http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX
/configuration/guide/pvlans.html#wp1143839>
*slot/port*] *switchport*

Verifies the configuration.

Regards

Martin
