1、1号设备关键配置点如下：

[H3C]irf member 1 renumber 1  //将1号设备配置为IRF成员1

[H3C]int range GigabitEthernet 1/0/2 to GigabitEthernet 1/0/3

[H3C-if-range]shutdown

[H3C-if-range]quit

[H3C]irf-port 1/1  //将物理端口绑定到IRF端口

[H3C-irf-port1/1]port group interface GigabitEthernet 1/0/2

[H3C-irf-port1/1]port group interface GigabitEthernet 1/0/3

[H3C-irf-port1/1]quit

[H3C]int range GigabitEthernet 1/0/2 to GigabitEthernet 1/0/3

[H3C-if-range]undo shutdown

[H3C-if-range]quit

[H3C]irf-port-configuration active  //激活IRF

[H3C]save  //保存配置

2、2号设备关键配置点如下：

[H3C]irf member 1 renumber 2  //将2号设备配置为IRF成员2

[H3C]int range GigabitEthernet 1/0/2 to GigabitEthernet 1/0/3

[H3C-if-range]shutdown

[H3C-if-range]quit

[H3C]irf-port 1/2  //将物理端口绑定到IRF口

[H3C-irf-port1/2]port group interface GigabitEthernet 1/0/2

[H3C-irf-port1/2]port group interface GigabitEthernet 1/0/3

[H3C-irf-port1/2]quit

[H3C]int range GigabitEthernet 1/0/2 to GigabitEthernet 1/0/3

[H3C-if-range]undo shutdown

[H3C-if-range]quit

[H3C]irf-port-configuration active  //激活IRF

[H3C]save //保存配置

3、分别重启设备1和设备2

4、测试

<H3C>dis irf   //查看IRF成员信息，发现设备1和设备2的信息都在一起
