1、先规划好需要做堆叠的端口与准备好堆叠线缆，堆叠口一般都是光口，看设备的情况而定。

2、将设备上电，并且使用堆叠线缆连接需要做堆叠设备与端口。

3、使用console线连接设备的console口开始配置。

4、配置如下：
①配置交换机的成员编号一般主的就是1，备的是2

主：
sys
[H3C]irf member 1 renumber 1 选择YES直接回车
[H3C]quit

备：
sys
[H3C]irf member 1 renumber 2 选择YES直接回车
[H3C]quit
重启备设备

②配置交换机的成员优先级
主：
sys
[H3C]irf member 1 priority 30
[H3C]quit
备：
sys
[H3C]irf member 1 priority 15
[H3C]quit

③配置irf端口，进入所需要配置堆叠的物理端口关闭端口
主：
sys
[H3C]int range Ten-GigabitEthernet 1/0/49 Ten-GigabitEthernet 1/0/50
[H3C-if-range]shutdown
[H3C-if-range]quit
[H3C]irf-port 1/1
[H3C-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/49
[H3C-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/50
[H3C-irf-port1/1]quit
[H3C]int range Ten-GigabitEthernet 1/0/49 Ten-GigabitEthernet 1/0/50
[H3C-if-range]undo shutdown
[H3C-if-range]quit
[H3C]save
[H3C] irf-port-configuration active

备：
sys
[H3C]int range Ten-GigabitEthernet 2/0/49 Ten-GigabitEthernet 2/0/50
[H3C-if-range]shutdown
[H3C-if-range]quit
[H3C]irf-port 1/1
[H3C-irf-port1/1]port group interface Ten-GigabitEthernet 2/0/49
[H3C-irf-port1/1]port group interface Ten-GigabitEthernet 2/0/50
[H3C-irf-port1/1]quit
[H3C]int range Ten-GigabitEthernet 2/0/49 Ten-GigabitEthernet 2/0/50
[H3C-if-range]undo shutdown
[H3C-if-range]quit
[H3C]save
[H3C] irf-port-configuration active

注：配置完成之后会开始竞选master，竞选完成之后slave会自动重启，
使用dis irf     查看堆叠情况 

④配置bfd检测堆叠
配置BFD MAC

[H3C] vlan 3
[H3C-vlan3] port ten-gigabitethernet 1/0/24 ten-gigabitethernet 2/0/24
[H3C-vlan3] quit

[H3C] interface vlan-interface 3
[H3C-Vlan-interface3] mad bfd enable
[H3C-Vlan-interface3] mad ip address 192.168.2.1 24 member 1
[H3C-Vlan-interface3] mad ip address 192.168.2.2 24 member 2
[H3C-Vlan-interface3] quit

#BFD和stp互斥，关闭stp
[H3C] interface gigabitethernet 1/0/24
[H3C-gigabitethernet-1/0/1] undo stp enable
[H3C-gigabitethernet-1/0/1] quit
[H3C] interface gigabitethernet 2/0/24
[H3C-gigabitethernet-2/0/1] undo stp enable
[H3C-gigabitethernet-2/0/1] quit
