switchport private-vlan host-association
switchport private-vlan host-association
To define a PVLAN association for an isolated or community port, use the switchport private-vlan
host-association command. To remove the PVLAN mapping from the port, use the no form of this
command.
switchport private-vlan host-association {primary-vlan-id} {secondary-vlan-id}
no switchport private-vlan host-association
Syntax Description
Defaults Private VLAN mapping is disabled.
Command Modes Interface configuration mode
Command History
Usage Guidelines There is no runtime effect on the port unless it is in PVLAN host mode. If the port is in PVLAN host
mode but all VLANs do not exist, the command is allowed, but the port is made inactive.
The secondary VLAN may be an isolated or community VLAN.
Examples This example shows how to configure a port with a primary VLAN (VLAN 18) and secondary VLAN
(VLAN 20):
Switch(config-if)# switchport private-vlan host-association 18 20
Switch(config-if)#
This example shows how to remove the PVLAN association from the port:
Switch(config-if)# no switchport private-vlan host-association
Switch(config-if)#
This example shows how to configure interface FastEthernet 5/1 as a PVLAN host port and verify the
configuration:
Switch# configure terminal
Switch(config)# interface fastethernet 5/1
Switch(config-if)# switchport mode private-vlan host
Switch(config-if)# switchport private-vlan host-association 202 440
primary-vlan-id Number of the primary VLAN of the PVLAN relationship; valid values are from
1 to 4094.
secondary-vlan-list Number of the secondary VLAN of the private VLAN relationship; valid values
are from 1 to 4094.
