Usage guidelines
The private-vlan isolated command takes effect when the following conditions exist:
• The secondary VLAN is associated with a primary VLAN.
• The ports are configured as host or trunk secondary ports of the secondary VLAN.
If you assign the downlink ports to a secondary VLAN configured with this command, the downlink
ports are isolated from each other at Layer 2.
The private-vlan isolated command is mutually exclusive with the primary VLAN, super VLAN, and
sub-VLAN configurations.
Examples
This example shows how to meet the following requirements:
• VLAN 4 is a secondary VLAN, and it is associated with primary VLAN 2.
• GigabitEthernet 1/0/1 is a promiscuous port of VLAN 2.
• GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 are host ports of VLAN 4.
• GigabitEthernet 1/0/2 and GigabitEthernet 1/0/3 are isolated at Layer 2 in secondary VLAN 4.
# Configure VLAN 2 as a primary VLAN and associate it with secondary VLAN 4.
