18.5.6 Displaying the Configuration Information of Private VLAN
Run the following commands in global, interface or VLAN configuration mode to display the private VLAN
configuration information of private VLAN and L2 port:
Command Purpose
show vlan private-vlan
Displays the configuration of private VLAN.
show vlan private-vlan interface interface
Displays the configuration of the L2 port in the private VLAN.
Configuration Example 18.6
Figure 1: Typical Configuration of Private VLAN
As shown in figure 1, port G0/1 is the promiscuous port in primary VLAN 2 and ports G0/2-G0/6 are host ports,
among which ports G0/2 and G0/3 are host ports (public ports) of Community VLAN 3, port G0/4 is that of
Community VLAN 4, and ports G0/5 and G0/6 are host ports of Isolated VLAN 5.
According to the definition of private VLAN, L2 communication can be conducted between promiscuous port
G0/1 and host ports of all sub-VLAN domains, so it is between host ports G0/2 and G0/3 of community VLAN
3, but they cannot conduct L2 communication with other host ports of secondary VLANs. L2 communication
cannot go on between ports G0/5 and G0/6 in Isolated VLAN 5, but the two ports can conduct L2
communication with promiscuous port G0/1.
The commands requiring to be entered in a switch are shown below:
Switch_config#interface GigaEthernet0/1
Switch_config_g0/1#switchport mode private-vlan promiscuous
Switch_config_g0/1#switchport private-vlan mapping 2 3-5
Switch_config_g0/1#switchport pvid 2
Switch_config#interface GigaEthernet0/2
Switch_config_g0/2#switchport mode private-vlan host
Switch_config_g0/2#switchport private-vlan host-association 2 3
Switch_config_g0/2#switchport pvid 3
