Configuring Private VLANs

Mapping Secondary VLANs to a Primary VLAN Layer 3 VLAN Interface

SUMMARY STEPS

1.configure terminal

2.interface vlan primary_vlan_id

3.private-vlan mapping [add remove] secondary_vlan_list

4.end

5.show interface private-vlan mapping

6.copy running-config startup config

DETAILED STEPS

 

Command or Action

Purpose

Step 1

configure terminal

Enters global configuration mode.

 

Example:

 

 

Switch# configure terminal

 

Step 2

interface vlan primary_vlan_id

Enters interface configuration mode for the primary VLAN, and

 

 

configures the VLAN as an SVI. The VLAN ID range is 2 to 1001

 

Example:

and 1006 to 4094.

 

Switch(config)# interface vlan 10

 

Step 3

private-vlan mapping [add remove]

 

secondary_vlan_list

Example:

Switch(config-if)# private-vlan mapping 501-502

Step 4

end

Example:

Switch(config-if)# end

Maps the secondary VLANs to the Layer 3 VLAN interface of a primary VLAN to allow Layer 3 switching of private VLAN ingress traffic.

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 primary VLAN.

Use the remove keyword with a secondary_vlan_list to clear the mapping between secondary VLANs and the primary VLAN.

Returns to privileged EXEC mode.

Step 5

show interface private-vlan mapping

Verifies the configuration.

Example:

Switch# show interfaces private-vlan
