Chapter 7 Configuring Private VLANs
Verifying Private VLAN Configuration
This example shows how to configure port 1/2 as a promiscuous port associated with the primary VLAN
5 and the secondary isolated VLAN 109:
switch# configure terminal
switch(config)# interface ethernet 1/2
switch(config-if)# switchport mode private-vlan promiscuous
switch(config-if)# switchport private-vlan mapping 5 109
You can only apply this command to a physical interface.
To clear the private VLAN mapping, perform this task:
Verifying Private VLAN Configuration
To display private VLAN configuration information, use the following commands:
The following example shows how to display the private VLAN configuration:
switch# show vlan private-vlan
Primary Secondary Type Ports
------- --------- --------------- -------------------------------------------
5 100 community
5 101 community Eth1/12, veth1/1
5 102 community
5 103 community
5 109 isolated Eth1/2
switch# show vlan private-vlan type
Vlan Type
---- -----------------
5 primary
Step 3
switch(config-if)# switchport mode
private-vlan promiscuous
Configures the port as a promiscuous port for a private
VLAN. You can only enable a physical Ethernet port
as the promiscuous port.
Step 4
switch(config-if)# switchport
private-vlan mapping {primary-vlan-id}
{secondary-vlan-list | add
secondary-vlan-list | remove
secondary-vlan-list}
Configures the port as a promiscuous port and
associates the specified port with a primary VLAN
and a selected list of secondary VLANs. The
secondary VLAN can be either an isolated or
community VLAN.
