private-vlan mapping
Use the private-vlan mapping interface configuration command on a switch virtual interface (SVI) to
create a mapping between a private-VLAN primary and secondary VLANs so that both VLANs share
the same primary VLAN SVI. Use the no form of this command to remove private-VLAN mappings
from the SVI.

Syntax Description
Defaults The default is to have no private VLAN SVI mapping configured.
Command Modes Interface configuration
Command History
Usage Guidelines The switch must be in VTP transparent mode when you configure private VLANs.
The SVI of the primary VLAN is created at Layer 3.
Configure Layer 3 VLAN interfaces (SVIs) only for primary VLANs. You cannot configure Layer 3
VLAN interfaces for secondary VLANs. SVIs for secondary VLANs are inactive while the VLAN is
configured as a secondary VLAN.
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. The list
can contain one isolated VLAN and multiple community VLANs.
Traffic that is received on the secondary VLAN is routed by the SVI of the primary VLAN.
A secondary VLAN can be mapped to only one primary SVI. IF you configure the primary VLAN as a
secondary VLAN, all SVIs specified in this command are brought down.
If you configure a mapping between two VLANs that do not have a valid Layer 2 private-VLAN
association, the mapping configuration does not take effect.
secondary-vlan-list Specify one or more secondary VLANs to be mapped to the primary VLAN
SVI.
add (Optional) Map the secondary VLAN to the primary VLAN SVI.
remove (Optional) Remove the mapping between the secondary VLAN and the
primary VLAN SVI.
