this command to remove the private-VLAN association or mapping from the port.
switchport private-vlan {association {host primary-vlan-id secondary-vlan-id | mapping
primary-vlan-id {add | remove} secondary-vlan-list} | host-association primary-vlan-id
secondary-vlan-id | mapping primary-vlan-id {add | remove} secondary-vlan-list}
no switchport private-vlan {association {host | mapping} | host-association | mapping
Syntax Description
Defaults The default is to have no private-VLAN association or mapping configured.
Command Modes Interface configuration
Command History
Usage Guidelines Private-VLAN association or mapping has no effect on the port unless the port has been configured as
a private-VLAN host or promiscuous port by using the switchport mode private-vlan {host |
promiscuous} interface configuration command.
If the port is in private-VLAN host or promiscuous mode but the VLANs do not exist, the command is
allowed, but the port is made inactive.
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.
association Define a private-VLAN association for a port.
host Define a private-VLAN association for a community or isolated host port.
primary-vlan-id The VLAN ID of the private-VLAN primary VLAN. The range is from 2 to

The range is from 2 to 1001 and 1006 to 4094.
