Chapter 2Catalyst 3750-E and 3560-E Switch Cisco IOS Commandsprivate-vlan mappingprivate-vlan mappingUse the private-vlan mapping interface configuration command on a switch virtual interface (SVI) onthe switch stack or on a standalone switch to create a mapping between a private-VLAN primary andsecondary VLANs so that both VLANs share the same primary VLAN SVI. Use the no form of thiscommand to remove private-VLAN mappings from the SVI.private-vlan mapping {[add | remove] secondary-vlan-list}no private-vlan mappingSyntax Descriptionsecondary-vlan-listaddremoveSpecify one or more secondary VLANs to be mapped to the primary VLANSVI.(Optional) Map the secondary VLAN to the primary VLAN SVI.(Optional) Remove the mapping between the secondary VLAN and theprimary VLAN SVI.DefaultsThe default is to have no private VLAN SVI mapping configured.Command ModesInterface configurationCommand HistoryRelease12.2(35)SE2ModificationThis command was introduced.Usage GuidelinesThe 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 3VLAN interfaces for secondary VLANs. SVIs for secondary VLANs are inactive while the VLAN isconfigured as a secondary VLAN.The secondary_vlan_list parameter cannot contain spaces. It can contain multiple comma-separateditems. Each item can be a single private-VLAN ID or a hyphenated range of private-VLAN IDs. The listcan 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 asecondary 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-VLANassociation, the mapping configuration does not take effect.OL-9776-08Catalyst 3750-E and 3560-E Switch Command Reference2-453
