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 interface. Use the no form of this command to remove private-VLAN mappings
from the interface.

Usage Guidelines
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 interface of the primary VLAN.
A secondary VLAN can be mapped to only one primary VLAN. 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.
