Configuring Private VLANs

Mapping Secondary VLANs to a Primary VLAN Layer 3 VLAN Interface

Command or Action

Purpose

mapping 20 add 501-503

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 private VLAN promiscuous port.

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

Step 5

end

Returns to privileged EXEC mode.

Example:

Switch(config-if)# end

Step 6

show interfaces [interface-id]switchport

Verifies the configuration.

Example:

Switch# show interfaces gigabitethernet1/0/2 switchport

Step 7

copy running-config startup config

Saves your entries in the switch startup configuration file.

Example:

Switch# copy running-config startup-config

Mapping Secondary VLANs to a Primary VLAN Layer 3 VLAN Interface

If the private VLAN will be used for inter-VLAN routing, you configure an SVI for the primary VLAN and map secondary VLANs to the SVI.

Isolated and community VLANs are both secondary VLANs.

The private-vlan mapping interface configuration command only affects private VLAN traffic that is Layer 3 switched.

Beginning in privileged EXEC mode, follow these steps to map secondary VLANs to the SVI of a primary VLAN to allow Layer 3 switching of private VLAN traffic:
