Table 4-1 shows a list of Cisco switches that support the PVLAN feature with the respective software version.
Configuring PVLAN
Note
When enabling PVLAN, it is important to remember to configure the switch as VTP transparent mode
before you can create a PVLAN. PVLANs are configured in the context of a single switch and cannot have
members on other switches.
Perform the following steps to configure the PVLAN feature:
Step 1. Create the primary and secondary PVLANs. For example, configure VLAN 101 as a primary VLAN,
VLANs 201 to 202 as community VLANs, and VLAN 301 as an isolated VLAN.
Hostname(config)# vlan 101
Hostname(config-vlan)# private-vlan primary
Hostname(config)# vlan 201
Hostname(config-vlan)# private-vlan community
Hostname(config)# vlan 202
Hostname(config-vlan)# private-vlan community
Hostname(config)# vlan 301
Hostname(config-vlan)# private-vlan isolated
Step 2. Associate the secondary VLANs to the primary PVLAN. For example, associate community VLANs
201 to 202 and isolated VLAN 301 with the primary VLAN 101.
Hostname(config)# vlan 101
Hostname(config-vlan)# private-vlan association 201-202,301
Hostname(config-vlan)# exit
Note
Only one isolated VLAN can be mapped to a primary VLAN, but multiple community
VLANs can be mapped to a primary VLAN.
