Usage guidelines
This command takes effect when the following conditions exist:
• The secondary VLAN is associated with a primary VLAN.
• The ports are configured as host ports or trunk secondary ports of the secondary VLAN.
This command is mutually exclusive with the primary VLAN, super VLAN, and sub-VLAN
configuration commands.
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.
• 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.
