Step 3
switch(config-if)# switchport mode private-vlan
host
Step 4

This example shows how to configure Ethernet port 1/12 as a host port for a private VLAN and associate it
to primary VLAN 5 and secondary VLAN 101:
switch# configure terminal
switch(config)# interface ethernet 1/12
switch(config-if)# switchport mode private-vlan host
switch(config-if)# switchport private-vlan host-association 5 101
Configuring an Interface as a Private VLAN Promiscuous Port
In a private VLAN domain, promiscuous ports are part of the primary VLAN. Configuring a promiscuous
port involves two steps. First, you define the port as a promiscuous port and then you configure the mapping
between a secondary VLAN and the primary VLAN.
Before You Begin
Ensure that the private VLAN feature is enabled.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# interface type slot/port
3. switch(config-if)# switchport mode private-vlan promiscuous
4. switch(config-if)# switchport private-vlan mapping {primary-vlan-id} {secondary-vlan-list | add
secondary-vlan-list | remove secondary-vlan-list}
5. (Optional) switch(config-if)# no switchport private-vlan mapping
