Chapter 2 Catalyst 3560 Switch Cisco IOS Commands switchport private-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. You can map a promiscuous port to only one primary VLAN. If you enter the switchport private-vlan mapping command on a promiscuous port that is already mapped to a primary and secondary VLAN, the primary VLAN mapping is overwritten. You can add or remove secondary VLANs from promiscuous port private-VLAN mappings by using the add and remove keywords. Entering the switchport private-vlan association host command has the same effect as entering the switchport private-vlan host-association interface configuration command. Entering the switchport private-vlan association mapping command has the same effect as entering the switchport private-vlan mapping interface configuration command.
