实验拓扑图

注意：

华三交换机堆叠业务口需要10G以上
接入加入IRF-port逻辑堆叠口之前需要shutdown关闭接口
逻辑堆叠口只有两个（x/1或者x/2）

实验步骤

SW1修改堆叠优先级

[SW1]irf member 1 priority 5     //修改优先级，默认华三默认为1

SW2修改堆叠编号

[SW2]irf member 1 renumber 2     //修改堆叠编号（2/0/1）
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y

SW1创建堆叠口

[SW1]interface Ten-GigabitEthernet 1/0/49     //进入接口
[SW1-Ten-GigabitEthernet1/0/49]shutdown     //关闭接口
[SW1-Ten-GigabitEthernet1/0/49]quit     //退出
[SW1]irf-port 1/1     //创建逻辑堆叠口
[SW1-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/49     //将接口加入到逻辑接口中
You must perform the following tasks for a successful IRF setup:
Save the configuration after completing IRF configuration.
Execute the "irf-port-configuration active" command to activate the IRF ports.
[SW1-irf-port1/1]quit     //退出
[SW1]interface Ten-GigabitEthernet 1/0/49     //进入接口
[SW1-Ten-GigabitEthernet1/0/49]undo shutdown     //开启端口
[SW1-Ten-GigabitEthernet1/0/49]quit     //退出
[SW1]irf-port-configuration active     //激活

SW2创建堆叠口

[SW2]int Ten-GigabitEthernet 2/0/49     //进入接口
[SW2-Ten-GigabitEthernet2/0/49]shutdown     //关闭接口
[SW2-Ten-GigabitEthernet2/0/49]quit     //退出
[SW2]irf-port 2/2
[SW2-irf-port2/2]port group interface Ten-GigabitEthernet 2/0/49     //将接口加入到逻辑接口中
You must perform the following tasks for a successful IRF setup:
Save the configuration after completing IRF configuration.
Execute the "irf-port-configuration active" command to activate the IRF ports.
[SW2-irf-port2/2]quit     //退出
[SW2]int Ten-GigabitEthernet 2/0/49     //进入接口
[SW2-Ten-GigabitEthernet2/0/49]undo shutdown     //开启端口
[SW2-Ten-GigabitEthernet2/0/49]quit     //退出
[SW2]irf-port-configuration active     //激活

SW1查看堆叠成员

[SW1]dis irf     //查看堆叠成员
