Configuring Private VLANs
Tasks for Configuring Private VLANs
To configure a private VLAN, perform these steps:
Step 1 Set VTP mode to transparent.
Step 2 Create the primary and secondary VLANs and associate them. See the “Configuring and Associating
VLANs in a Private VLAN” section on page 14-9.
Note If the VLAN is not created already, the private-VLAN configuration process creates it.
Step 3 Configure interfaces to be isolated or community host ports, and assign VLAN membership to the host
port. See the “Configuring a Layer 2 Interface as a Private-VLAN Host Port” section on page 14-11.
Step 4 Configure interfaces as promiscuous ports, and map the promiscuous ports to the primary-secondary
VLAN pair. See the “Configuring a Layer 2 Interface as a Private-VLAN Promiscuous Port” section on
page 14-12.
Step 5 If inter-VLAN routing will be used, configure the primary SVI, and map secondary VLANs to the
primary. See the “Mapping Secondary VLANs to a Primary VLAN Layer 3 VLAN Interface” section on
page 14-13.
Step 6 Verify private-VLAN configuration.
Default Private-VLAN Configuration
No private VLANs are configured.
Private-VLAN Configuration Guidelines
Guidelines for configuring private VLANs fall into these categories:
• Secondary and Primary VLAN Configuration, page 14-6
• Private-VLAN Port Configuration, page 14-8
• Limitations with Other Features, page 14-8
Secondary and Primary VLAN Configuration
Follow these guidelines when configuring private VLANs:
• Set VTP to transparent mode. After you configure a private VLAN, you should not change the VTP
mode to client or server. For information about VTP, see Chapter 12, “Configuring VTP.”
• You must use VLAN configuration (config-vlan) mode to configure private VLANs. You cannot
configure private VLANs in VLAN database configuration mode. For more information about
VLAN configuration, see “VLAN Configuration Mode Options” section on page 11-7.
