Private-Vlan Mapping - Cisco 4500M Command Reference Manual

Chapter2 Cisco IOS Commands for the Catalyst 4500 Series Switches

private-vlan mapping

To create a mapping between the primary and the secondary VLANs, so that both share the same primary
VLAN SVI, use the private-vlan mapping command. To remove all PVLAN mappings from an SVI, use
the no form of the command.
Syntax Description
primary-vlan-id
secondary-vlan-list

Defaults
All PVLAN mappings are removed.

Command History Release
12.1(8a)EW
Usage Guidelines
The secondary_vlan_list parameter cannot contain spaces. It can contain multiple, comma-separated
items. Each item can be a single PVLAN ID or a range of PVLAN IDs separated by hyphens.
This command is valid in the interface configuration mode of the primary VLAN.
The SVI of the primary VLAN is created at Layer 3.
Traffic received on the secondary VLAN is routed by the SVI of the primary VLAN.
The SVIs of existing secondary VLANs do not function and are considered down after this command is
entered.
A secondary SVI can be mapped to only one primary SVI. If the configured PVLANs association is
different from what is specified in this command, for example if the specified primary-vlan-id is
configured as a secondary VLAN, all the SVIs specified in this command are brought down.
If you configure a mapping between two VLANs that do not have a valid Layer 2 association, the
mapping configuration does not take effect.
