组网需求
• Device B 上的VLAN 5 和VLAN 10 为Primary VLAN，其上行端口GigabitEthernet1/0/1
需要允许VLAN 5 和VLAN 10 的报文携带VLAN Tag 通过。
• Device B 的下行端口GigabitEthernet1/0/2 允许Secondary VLAN 2 通过，
GigabitEthernet1/0/3 允许Secondary VLAN 3 通过，VLAN 2 和VLAN 3 映射到Primary
VLAN 5。
• Device B 的下行端口GigabitEthernet1/0/6 允许Secondary VLAN 6 通过，
GigabitEthernet1/0/8 允许Secondary VLAN 8 通过，VLAN 6 和VLAN 8 映射到Primary
VLAN 10。
• 从 Device A 看，下接的Device B 只有VLAN 5 和VLAN 10。
配置步骤
(1) 配置 Device B
配置VLAN 5 和VLAN 10 为Primary VLAN。
<DeviceB> system-view
[DeviceB] vlan 5
[DeviceB-vlan5] private-vlan primary
[DeviceB-vlan5] quit
[DeviceB] vlan 10
[DeviceB-vlan10] private-vlan primary
[DeviceB-vlan10] quit

创建Secondary VLAN 2、3、6、8。
[DeviceB] vlan 2 to 3
[DeviceB] vlan 6
[DeviceB-vlan6] quit
[DeviceB] vlan 8
[DeviceB-vlan8] quit

配置上行端口 GigabitEthernet1/0/1 在VLAN 5 和VLAN 10 中工作在trunk promiscuous 模
式。
[DeviceB] interface gigabitethernet 1/0/1
[DeviceB- GigabitEthernet1/0/1] port private-vlan 5 10 trunk promiscuous
[DeviceB- GigabitEthernet1/0/1] quit

将下行端口 GigabitEthernet1/0/2 加入VLAN 2， GigabitEthernet1/0/3 加入VLAN 3，并
配置他们工作在host 模式。
[DeviceB] interface gigabitethernet 1/0/2
[DeviceB- GigabitEthernet1/0/2] port access vlan 2

[DeviceB- GigabitEthernet1/0/2] port private-vlan host
[DeviceB- GigabitEthernet1/0/2] quit
[DeviceB] interface ten-gigabitethernet 1/0/3
[DeviceB- GigabitEthernet1/0/3] port access vlan 3
[DeviceB- GigabitEthernet1/0/3] port private-vlan host
[DeviceB- GigabitEthernet1/0/3] quit

配置Primary VLAN 5 和Secondary VLAN 2、3 间的映射关系。
[DeviceB] vlan 5
[DeviceB-vlan5] private-vlan secondary 2 to 3
[DeviceB-vlan5] quit

将下行端口 GigabitEthernet1/0/6 加入VLAN 6， GigabitEthernet1/0/8 加入VLAN 8，并
配置它们工作在host 模式。
[DeviceB] interface gigabitethernet 1/0/6
[DeviceB- GigabitEthernet1/0/6] port access vlan 6
[DeviceB- GigabitEthernet1/0/6] port private-vlan host
[DeviceB- GigabitEthernet1/0/6] quit
[DeviceB] interface gigabitethernet 1/0/8
[DeviceB- GigabitEthernet1/0/8] port access vlan 8
[DeviceB- GigabitEthernet1/0/8] port private-vlan host
[DeviceB- GigabitEthernet1/0/8] quit

配置Primary VLAN 10 和Secondary VLAN 6、8 间的映射关系。
[DeviceB] vlan 10
[DeviceB-vlan10] private-vlan secondary 6 8
[DeviceB-vlan10] quit

(2) 配置Device A

创建VLAN 5 和VLAN 10。
[DeviceA] vlan 5
[DeviceA-vlan5] quit
[DeviceA] vlan 10
[DeviceA-vlan10] quit

配置端口 GigabitEthernet1/0/1 为Hybrid 端口，并允许VLAN 5 和VLAN 10 携带Tag 通过。
[DeviceA] interface gigabitethernet 1/0/1
[DeviceA- GigabitEthernet1/0/1] port link-type hybrid
[DeviceA- GigabitEthernet1/0/1] port hybrid vlan 5 10 tagged
[DeviceA- GigabitEthernet1/0/1] quit

显示与验证
显示Device B 上的Primary VLAN 5 配置情况（Primary VLAN 10 的显示结果类似，这里不再列
出）。
[DeviceB] display private-vlan 5
Primary VLAN ID: 5
Secondary VLAN ID: 2-
