目 录
本文档介绍基于端口的VLAN、Super VLAN、Private VLAN的典型应用场景和配置举例。
本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。
本文档假设您已了解VLAN特性。
如图1所示，Host A和Host C属于部门A，但是通过不同的设备接入公司网络；Host B和Host D属于部门B，也通过不同的设备接入公司网络。为了通信的安全性，以及避免广播报文泛滥，公司网络中使用VLAN技术来隔离部门间的二层流量。其中部门A使用VLAN 100，部门B使用VLAN 200。
现要求同一VLAN内的主机能够互通，即Host A和Host C能够互通，Host B和Host D能够互通。
图1 基于端口的VLAN组网图
# 批量配置接口Ten-GigabitEthernet1/0/1～Ten-GigabitEthernet1/0/3工作在二层模式。
[DeviceA] interface range ten-gigabitethernet 1/0/1 to ten-gigabitethernet 1/0/3
[DeviceA-if-range] port link-mode bridge
[DeviceA-if-range] quit
# 创建VLAN 100，并将Ten-GigabitEthernet1/0/1加入VLAN 100。
[DeviceA-vlan100] port ten-gigabitethernet 1/0/1
[DeviceA-vlan100] quit
# 创建VLAN 200，并将Ten-GigabitEthernet1/0/2加入VLAN 200。
[DeviceA-vlan200] port ten-gigabitethernet 1/0/2
[DeviceA-vlan200] quit
# 为了使Device A上VLAN 100和VLAN 200的报文能发送给Device B，将Ten-GigabitEthernet1/0/3的链路类型配置为Trunk，并允许VLAN 100和VLAN 200的报文通过。
[DeviceA] interface ten-gigabitethernet 1/0/3
[DeviceA-Ten-GigabitEthernet1/0/3] port link-type trunk
[DeviceA-Ten-GigabitEthernet1/0/3] port trunk permit vlan 100 200
(2) Device B上的配置与Device A上的配置相同，不再赘述。
(3) 将Host A和Host C配置在一个网段，例如192.168.100.0/24；将Host B和Host D配置在一个网段，比如192.168.200.0/24。
(1) Host A和Host C能够互相ping通，但是均不能ping通Host B。Host B和Host D能够互相ping通，但是均不能ping通Host A。
# 查看Device A上VLAN 100和VLAN 200的配置信息，VLAN 100的报文仅允许通过接口XGE1/0/3和XGE1/0/1，VLAN 200的报文仅允许通过接口XGE1/0/3和XGE1/0/2。

如图2所示：
· VLAN 2中的用户通过Device A的Ten-GigabitEthernet1/0/1接入网络，VLAN 3中的用户通过Device A的Ten-GigabitEthernet1/0/2接入网络。VLAN 2中有30个用户，VLAN 3中有50个用户。
· Device A的Ten-GigabitEthernet1/0/3和Device B的Ten-GigabitEthernet1/0/1属于VLAN 20。
· VLAN 20中的终端用户都使用192.168.2.0/24 网段的IP地址，使用192.168.2.1作为网关地址。
现要求通过配置Super VLAN功能实现以下应用需求：
· VLAN 2和VLAN 3中的终端用户都使用192.168.1.0/24网段的IP地址以节省IP地址资源，使用192.168.1.1作为网关地址。
· VLAN 2、VLAN 3、VLAN 20中的终端用户二层隔离，三层互通。
由于Super VLAN中不能包含物理端口，由此若某VLAN中已经包含物理端口，则该VLAN不能被配置为Super VLAN。

(1) 查看Super VLAN配置信息。

(2) Host A和Host B可以互相ping通。查看Host A的ARP表，表中Host B的IP地址对应的MAC地址是Vlan-interface10的MAC地址。查看Host B的ARP表，表中Host A的IP地址对应的MAC地址也是Vlan-interface10的MAC地址。
(3) Host A和Host C可以互相ping通。查看Host A的ARP表，表中没有Host C的ARP表项。查看Host C的ARP表，表中也没有Host A的ARP表项。说明VLAN 2和VLAN 20二层隔离，三层互通。Host B和Host C互相ping的情况同理。

如图3所示：
· 汇聚层设备Device A为接入设备Device B分配了VLAN 10，网关接口VLAN-interface10可以和所有用户互通，以便用户可以通过Device A来访问外部网络。Device B连接的所有用户均处于同一网段10.0.0.0/24。
· Host A和B属于销售部，Host C和D属于财务部。为保证安全，需要使不同部门之间二层隔离，同部门的用户之间则可以互通。
现由于Device A不能为Device B分配更多VLAN，要求通过Private VLAN功能实现：
· Device A只需识别VLAN 10。
· Device B在Primary VLAN 10下为各部门配置不同的Secondary VLAN，使部门间二层隔离。
图3 Private VLAN典型配置举例组网图
Private VLAN功能只需要在接入设备Device B上配置。
系统缺省VLAN（VLAN 1）不支持Private VLAN相关配置。
