switchport private-vlan
switchport private-vlan
Use the switchport private-vlan interface configuration command on the switch stack or on a standalone
switch to define a private-VLAN association for an isolated or community port or a mapping for a
promiscuous port. Use the no form of this command to remove the private-VLAN association or
mapping from the port.
This command is supported only if the switch or stack master is running the IP services feature set. In a
switch stack, we strongly recommend that the stack members also run the IP services feature set when
private VLANs are configured.

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.
