8.5.4 创建PVLAN

在IOS和CatOS系统交换机中都可以配置PVLAN，所以下面也分别予以介绍。

1. IOS系统交换机的PVLAN创建

在IOS系统交换机中，创建一个PVLAN的步骤如表8-18所示。.

表8-18 配置VLAN作为PVLAN的步骤

命令

用途

Step 1 

Switch(config)# vlan vlan_ID

键入要配置的VLAN的VLAN ID，进入VLAN配置模式

Step 2 

Switch(config-vlan)# private-vlan {community | isolated | primary}

配置该VLAN为PVLAN

Switch(config-vlan)# no private-vlan {community | isolated | primary}

清除PVLAN配置。这个命令的配置要到退出VLAN配置模式后才会生效

Step 3 

Switch(config-vlan)# end

退出VLAN配置模式

Step 4 

Switch# show vlan private-vlan [type]

校验以上配置

以下示例显示如何配置VLAN 202作为一个主VLAN（primary VLAN），并校验配置。

Switch# configure terminal

Switch(config)# vlan 202

Switch(config-vlan)# private-vlan primary

Switch(config-vlan)# end

Switch# show vlan private-vlan

Primary Secondary Type Interfaces

------- --------- ----------------- ------------------------------------------

202 primary

以下示例显示如何配置VLAN 303作为公共VLAN（community VLAN），并校验配置。

Switch# configure terminal

Switch(config)# vlan 303

Switch(config-vlan)# private-vlan community

Switch(config-vlan)# end

Switch# show vlan private-vlan

Primary Secondary Type Interfaces

------- --------- ----------------- ------------------------------------------

202 primary

303 community

以下示例显示如何配置VLAN 440作为一个隔离VLAN（isolated VLAN），并校验配置。

Switch# configure terminal

Switch(config)# vlan 440

Switch(config-vlan)# private-vlan isolated

Switch(config-vlan)# end

Switch# show vlan private-vlan

Primary Secondary Type Interfaces

------- --------- ----------------- ------------------------------------------

202 primary

303 community

440 isolated

2. CatOS系统交换机的PVLAN创建

你可以使用“set pvlan primary_vlan_num {isolated_vlan_num | community_vlan_num}”命令绑定没有与隔离端口（isolated port）或者公共端口（community port）关联的隔离VLAN（isolated VLAN）或者公共VLAN（community VLAN）到主VLAN（private VLAN）中。也可以使用“set pvlan primary_vlan_num {isolated_vlan_num | community_vlan_num} mod/port”命令改变PVLAN中的隔离或者公共端口，而不用改变隔离或者公共VLAN。

你必须键入“set pvlan”命令来创建PVLAN，具体的步骤如表8-19所示。

表8-19 在CatoS系统交换机上创建PVLAN的步骤

命令

用途说明

Step 1 

Console> (enable) set vlan vlan_num pvlan-type primary

创建主VLAN

Step 2 

Console> (enable) set vlan vlan_num pvlan-type {isolated | community}

设置隔离或者公共VLAN

Step 3 

Console> (enable)set pvlan primary_vlan_num {isolated_vlan_num | community_vlan_num}mod/ports

绑定隔离或者公共VLAN到主VLAN中，并把隔离或者公共VLAN与PVLAN进行关联

Step 4 

Console> (enable) set pvlan mapping primary_vlan_num {isolated_vlan_num | community_vlan_num} mod/ports

在混杂端口上映射隔离、公共VLAN到主VLAN

Step 5 

Console> (enable) show pvlan [vlan_num]

Console> (enable) show pvlan mapping

校验PVLAN配置

以下示例显示了如何使用VLAN 7作为主VLAN，VLAN 901作为隔离VLAN，VLAN 902和VLAN 903作为公共VLAN来创建一个PLAVN。VLAN 901使用模块4的端口3；VLAN 902使用模块4的端口4~6；VLAN 903使用模块4的端口7~9。路由器是连接到混杂端口3/1上的。

在开始编辑没有分配端口的VLAN 7、901、902、903前，使用“show vlan vlan_num”命令查看各VLAN中端口成员。如果在这些VLAN中，已分配了任何端口，使用“set vlan vlan_num {mod/port}”命令设置它们到其他适当的VLAN中。

以下示例显示了如何指定VLAN 7作为主LVAN。

Console> (enable) set vlan 7 pvlan-type primary

Vlan 7 configuration successful

Console> (enable)

以下示例显示如何指定VLAN 901作为隔离VLAN，VLAN 902和VLAN 903作为公共VLAN。

Console> (enable) set vlan 901 pvlan-type isolated

Vlan 901 configuration successful

Console> (enable) set vlan 902 pvlan-type community

Vlan 902 configuration successful

Console> (enable) set vlan 903 pvlan-type community

Vlan 903 configuration successful

Console> (enable)

以下示例显示如何绑定VLAN 901到主VLAN 7中，并指定端口4/3作为隔离端口。

Console> (enable) set pvlan 7 901 4/3

Successfully set the following ports to Private Vlan 7,901: 4/3

Console> (enable)

以下示例显示如何绑定VLAN 902到主VLAN 7中，并指定端口4/4~4/6作为隔离端口。

Console> (enable) set pvlan 7 902 4/4-6

Successfully set the following ports to Private Vlan 7,902:4/4-6

Console> (enable)

以下示例显示如何绑定VLAN 903到主VLAN 7中，并指定端口4/7~4/9作为隔离端口。

Console> (enable) set pvlan 7 903

Successfully set association between 7 and 903.

Console> (enable) set pvlan 7 903 4/7-9

Successfully set the following ports to Private Vlan 7,903:4/7-9

Console> (enable)

以下示例显示如何在混杂端口3/1上映射每个隔离和公共VLAN流量到主VLAN。

Console> (enable) set pvlan mapping 7 901 3/1

Successfully set mapping between 7 and 901 on 3/1

Console> (enable) set pvlan mapping 7 902 3/1

Successfully set mapping between 7 and 902 on 3/1

Console> (enable) set pvlan mapping 7 903 3/1

Successfully set mapping between 7 and 903 on 3/1

以下示例显示如何校验PVLAN配置。

Console> (enable) show vlan 7
