在对交换机进行VLAN配置的时候,需要在每一台交换机上手工创建该交换机需要涉及的所有VLAN,并且需要手工将交换机上的各个端口加入到相应的VLAN中去。如果交换机和VLAN的数量太多,特别是VLAN的数量又经常变化时,则这种手工配置方式既耗费时间有耗费精力,又非常容易出错。

为此IEEE制定了一个名为GARP(通用属性注册协议)的框架协议,该框架协议包括两个具体的协议:GMRP(组播注册协议)和GVRP(通用VLAN注册协议)。GVRP的主要作用是:自动实现VLAN信息在交换机上的动态注册过程和注销过程;GVRP的应用大大地降低了VLAN配置爱过程中的手工工作背景。

使用方法:

1.在使能(开启)端口的GVRP功能之前,需要先全局使能GVRP功能

2.配置相关的端口为Trunk,并允许相应的VLAN通过,并且GVRP功能只能配置在Trunk类型的端口上

GVRP动态注册VLAN过程:

1.在下面的拓扑图中,假设PC1和PC2都被划分到VLAN10,所有的交换机都已经全局使用了GVRP功能,并且相应的端口也使能了GVRP功能,当用户手动在SWI1上创建VLAN10,并且配置swi1的GE0/0/2端口允许属于VLAN 10的帧通过后,swi1的GE0/0/2端口会向外发送VLAN属性的注册报文,swi2的GE0/0/1端口接收到swi1发送过来的VLAN属性的注册报文之后,会自动的创建动态VLAN 10,并将自己的GE0/0/1端口注册到动态VLAN 10中,以此类推,当VLAN属性的单行注册过程完毕之后,只有swi2的GE0/0/1,swi3的GE0/0/2和swi4的GE0/0/2被加入到了动态VLAN 10中

2.在swi4中手动创建静态VLAN 10,并且配置swi4的GE0/0/2端口允许属于VLAN 10的帧通过后,swi3的GE0/0/1,swi2的GE0/0/2被加入到了动态VLAN 10中。

[3-GigabitEthernet0/0/2]quit 

swi4:

<Huawei>system-view 
[Huawei]sysname 4
	
[4]gvrp

三:实验检查:

1.swi1:

通过display gvrp statistics查看端口GVRP统计情况:

[1]display gvrp statistics

  GVRP statistics on port GigabitEthernet0/0/2 
    GVRP status				: Enabled
    GVRP registrations failed		: 0
    GVRP last PDU origin		: 4c1f-cc66-2a04
    GVRP registration type		: Normal

GVRP status                : Enabled说明swi1的GE0/0/2端口已经使能(开启)了GVRP功能!

通过display vlan summary 查看VLAN信息:

[1]display vlan summary 
static vlan:
Total 2 static vlan.
  1 10 

dynamic vlan:
Total 0 dynamic vlan.

reserved vlan:
Total 0 reserved vlan.

从显示的信息就可以看出,swi1上已经存在动态VLAN10.
