Chapter 1 Configuring Private VLANs
Configuring Private VLANs
• If two stacks merge, private VLANs on the winning stack are not affected, but private-VLAN
configuration on the losing switch is lost when that switch reboots.
For more information about switch stacks, see Chapter 1, “Managing Switch Stacks.”
Configuring Private VLANs
These sections contain this configuration information:
• Tasks for Configuring Private VLANs, page 1-6
• Default Private-VLAN Configuration, page 1-6
• Private-VLAN Configuration Guidelines, page 1-7
• Configuring and Associating VLANs in a Private VLAN, page 1-10
• Configuring a Layer 2 Interface as a Private-VLAN Host Port, page 1-11
• Configuring a Layer 2 Interface as a Private-VLAN Promiscuous Port, page 1-13
• Mapping Secondary VLANs to a Primary VLAN Layer 3 VLAN Interface, page 1-13
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 1-10.
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 1-11.
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 1-13.
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 1-13.
Step 6 Verify private-VLAN configuration.
Default Private-VLAN Configuration
No private VLANs are configured.
