Examples

This example shows how to meet the following requirements:

• VLAN 4 is a secondary VLAN, and it is associated with primary VLAN 2.

• Ten-GigabitEthernet 1/0/1 is a promiscuous port of VLAN 2.

• Ten-GigabitEthernet 1/0/2 and Ten-GigabitEthernet 1/0/3 are host ports.

• Ten-GigabitEthernet 1/0/2 and Ten-GigabitEthernet 1/0/3 can communicate at Layer 2 in secondary VLAN 4.

# Configure VLAN 2 as a primary VLAN and associate it with secondary VLAN 4.

<Sysname> system-view
[Sysname] vlan 4
[Sysname-vlan4] quit
[Sysname] vlan 2
[Sysname-vlan2] private-vlan primary
[Sysname-vlan2] private-vlan secondary 4
[Sysname-vlan2] quit

# Configure Ten-GigabitEthernet 1/0/1 as a promiscuous port of VLAN 2.

[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] port private-vlan 2 promiscuous
[Sysname-Ten-GigabitEthernet1/0/1] quit

# Assign Ten-GigabitEthernet 1/0/2 to VLAN 4 and configure the port as a host port.

[Sysname] interface ten-gigabitethernet 1/0/2
[Sysname-Ten-GigabitEthernet1/0/2] port access vlan 4
[Sysname-Ten-GigabitEthernet1/0/2] port private-vlan host
[Sysname-Ten-GigabitEthernet1/0/2] quit

# Assign Ten-GigabitEthernet 1/0/3 to VLAN 4 and configure the port as a host port.

[Sysname] interface ten-gigabitethernet 1/0/3
[Sysname-Ten-GigabitEthernet1/0/3] port access vlan 4
[Sysname-Ten-GigabitEthernet1/0/3] port private-vlan host
[Sysname-Ten-GigabitEthernet1/0/3] quit
