【SW1】

1.修改member 1的优先级，使其成为domain1 中的master设备

[SW1]irf domain 1

[SW1]irf member 1 priority 10

2.关闭Ten1/0/50和Ten1/0/51接口

[SW1]interface range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
[SW1-if-range]shutdown
[SW1-if-range]quit

3.创建IRF接口组1/1，并管理接口Ten1/0/50和Ten1/0/51接口

[SW1]irf-port 1/1
[SW1-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/50
[SW1-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/51
[SW1-irf-port1/1]quit

4.开启en1/0/50和Ten1/0/51接口

[SW1]interface range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
[SW1-if-range]undo shutdown
[SW1-if-range]quit

5.激活IRF的配置

[SW1]irf-port-configuration active

6.保存配置信息，重启设备

save
y
reboot
y

【SW2】

7.将SW2设备修改为domain1中的member2设备

[SW2]irf domian 1

[SW2]irf member 1 renumber 2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y

8.保存配置信息，重启设备

save
y
reboot
y

9.关闭Ten2/0/50和Ten2/0/51接口

[SW2]interface range Ten-GigabitEthernet 2/0/50 to Ten-GigabitEthernet 2/0/51
[SW2-if-range]shutdown
[SW2-if-range]quit

10.创建IRF接口组2/2，并管理接口Ten2/0/50和Ten2/0/51接口

[SW2]irf-port 2/2
[SW2-irf-port2/2]port group interface Ten-GigabitEthernet 2/0/50
[SW2-irf-port2/2]port group interface Ten-GigabitEthernet 2/0/51
[SW2-irf-port2/2]quit

11.开启接口Ten2/0/50和Ten2/0/51接口

[SW2]interface range Ten-GigabitEthernet 2/0/50 to Ten-GigabitEthernet 2/0/51
[SW2-if-range]undo shutdown
[SW2-if-range]quit

12.激活IRF的配置

[SW2]irf-port-configuration active

13.保存配置信息，重启设备

save
y
reboot
y

14.连线

15.验证

15.1发现SW2设备名称已经被改为了SW1

并且，在原SW2设备上查看接口信息，发现既有SW1的接口，又有原SW2的接口

15.2在原SW1和原SW2上查看IRF状态
