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
本举例是在S6860-CMW710-R2612版本上进行配置和验证的。
# 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。
[DeviceA-Ten-GigabitEthernet1/0/3] display vlan 100
VLAN ID: 100
VLAN type: Static
Route interface: Not configured
Description: VLAN 0100
Name: VLAN 0100
Tagged ports:
Ten-GigabitEthernet1/0/3
Untagged ports:
Ten-GigabitEthernet1/0/1
[DeviceA-Ten-GigabitEthernet1/0/3] display vlan 200
VLAN ID: 200
VLAN type: Static
Route interface: Not configured
Description: VLAN 0200
Name: VLAN 0200
Tagged ports:
Ten-GigabitEthernet1/0/3
Untagged ports:
Ten-GigabitEthernet1/0/2
Device B上的配置与Device A上的配置相同,此处仅以Device A的配置文件举例。

#

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。
本举例是在S6860-CMW710-R2612版本上进行配置和验证的。
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。
[DeviceA] display supervlan
Super VLAN ID: 10
Sub-VLAN ID: 2-3
VLAN ID: 10
VLAN type: Static
It is a super VLAN.

Untagged ports: none
VLAN ID: 2

(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。
本举例是在S6860-CMW710-R2612版本上进行配置和验证的。
系统缺省VLAN(VLAN 1)不支持Private VLAN相关配置。
# 配置VLAN 10为Primary VLAN。
