H3C设备堆叠（实用）

H3C设备实用设备堆叠步骤（简单使用，思路清晰），供大家参考学习

**1.主设备
interface GigabitEthernet 1/0/9 – 进入端口
shutdown – 关闭端口
quit
irf member 1 priority 32 – 配置当前irf成员id 1的优先级为32
irf-port 1/2
port group interface GigabitEthernet 1/0/9
irf-port-con active – 激活irf端口配置
undo shutdown – 开启端口
save – 保存配置

2.备设备
irf member 1 renumber 2
reboot
irf member 2 priority 10
interface GigabitEthernet2/0/9
shutdown
irf-port 2/1
port group interface GigabitEthernet2/0/9
irf-port-con active
interface GigabitEthernet2/0/9
undo shutdown
save
3.MAD BFD 检测
vlan 3090（随意大一些，避免与业务vlan冲突）
interface Vlan-interface 3090
mad bfd enable
mad ip address 2.2.2.1 255.255.255.252 member 1
mad ip address 2.2.2.2 255.255.255.252 member 2
int g1/0/24 port access vlan 3090
int g2/0/24 port access vlan 3090
interface GigabitEthernet1/0/24
undo stp enable
interface GigabitEthernet2/0/24
undo stp enable
save
