3 配置步骤

3.1 配置IRF2

3.1.1 配置设备编号

# Device A保留缺省编号为1，不需要进行配置。同时，在Device B上将设备的成员编号修改为2。

<DeviceB> system-view

[DeviceB] irf member 1 renumber 2

Warning: Renumbering the switch number may result in configuration change or loss. Continue? [Y/N]:y

[DeviceB]

3.1.2 配置堆叠口

#将两台设备断电后，按组网图所示连接IRF链路，然后将两台设备上电。在Device A上创建设备的IRF端口2，与物理端口Ten-GigabitEthernet1/0/25、 Ten-GigabitEthernet1/0/26绑定，并保存配置。

<DeviceA> system-view

[DeviceA] interface ten-gigabitethernet 1/0/25

[DeviceA-Ten-GigabitEthernet1/0/25] shutdown

[DeviceA-Ten-GigabitEthernet1/0/25] quit
[DeviceA] interface ten-gigabitethernet 1/0/26

[DeviceA-Ten-GigabitEthernet1/0/26] shutdown

[DeviceA-Ten-GigabitEthernet1/0/26] quit

[DeviceA] irf-port 1/2

[DeviceA-irf-port1/2] port group interface ten-gigabitethernet1/0/25

[DeviceA-irf-port1/2] port group interface ten-gigabitethernet1/0/26

[DeviceA-irf-port1/2] quit

[DeviceA] interface ten-gigabitethernet 1/0/25

[DeviceA-Ten-GigabitEthernet1/0/25] undo shutdown

[DeviceA-Ten-GigabitEthernet1/0/25] quit

[DeviceA] interface ten-gigabitethernet 1/0/26

[DeviceA-Ten-GigabitEthernet1/0/26] undo shutdown

[DeviceA-Ten-GigabitEthernet1/0/26] quit

[DeviceA] save force

# 在Device B上创建设备的IRF端口1，与物理端口Ten-GigabitEthernet2/0/25、Ten-GigabitEthernet2/0/26绑定，并保存配置。

<DeviceB> system-view

[DeviceB] interface ten-gigabitethernet 2/0/25

[DeviceB-Ten-GigabitEthernet2/0/25] shutdown

[DeviceB-Ten-GigabitEthernet2/0/25] quit

[DeviceB] interface ten-gigabitethernet 2/0/26

[DeviceB-Ten-GigabitEthernet2/0/26] shutdown

[DeviceB-Ten-GigabitEthernet2/0/26] quit

[DeviceB] irf-port 2/1

[DeviceB-irf-port2/1] port group interface ten-gigabitethernet2/0/25

[DeviceB-irf-port2/1] port group interface ten-gigabitethernet2/0/26

[DeviceB-irf-port2/1] quit

[DeviceB] interface ten-gigabitethernet 2/0/25

[DeviceB-Ten-GigabitEthernet2/0/25] undo shutdown

[DeviceB-Ten-GigabitEthernet2/0/25] quit

[DeviceB] interface ten-gigabitethernet 2/0/26

[DeviceB-Ten-GigabitEthernet2/0/26] undo shutdown

[DeviceB-Ten-GigabitEthernet2/0/26] quit

[DeviceB] save force

# 激活DeviceA的IRF端口配置。

[DeviceA] irf-port-configuration active

# 激活DeviceB的IRF端口配置。

[DeviceB] irf-port-configuration active

#两台设备间将会进行Master竞选，竞选失败的一方将自动重启，重启完成后，IRF形成，系统名称统一为DeviceA

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
