⚠注意：sw2 的 ID 需要修改为 2 → 修改后必须重启设备才生效！

🛠二、SW1（主设备）配置

1⃣ 进入系统并设置优先级

sys
irf member 1 priority 32   # 设置优先级为32，更容易成为主

2⃣ 关闭 IRF 端口用于配置

interface range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
shutdown
quit

3⃣ 绑定 IRF 端口

irf-port 1/2
port group interface Ten-GigabitEthernet 1/0/49
port group interface Ten-GigabitEthernet 1/0/50
quit

4⃣ 启用 IRF 端口

interface range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
undo shutdown
quit

5⃣ 保存配置并激活

save
irf-port-configuration active

🔧三、SW2（从设备）配置

1⃣ 修改设备 ID（重启后生效）

sys
irf member 1 renumber 2   # 修改成员 ID 为2，必须重启设备
# 需要重启生效

2⃣ 设置优先级

irf member 2 priority 28   # 优先级低于主设备

3⃣ 关闭 IRF 端口用于配置

interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
shutdown
quit

4⃣ 绑定 IRF 端口

irf-port 2/1
port group interface Ten-GigabitEthernet 2/0/49
port group interface Ten-GigabitEthernet 2/0/50
quit

5⃣ 启用 IRF 端口

interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
undo shutdown
quit

6⃣ 保存并激活端口配置

save
irf-port-configuration active

7⃣ ⚠最后需要重启 sw2

reboot

🔁四、物理连线完成后

把 49 ↔ 49、50 ↔ 50 接好，然后重启 sw2。

系统起来后输入以下命令查看堆叠状态：

display irf
display irf topology
display version

正常情况应看到：

MemberID  Role    Priority
1         Master  32
2         Slave   28

✅五、所有命令汇总（可直接一键复制）

SW1

sys
irf member 1 priority 32
interface range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
shutdown
qu
irf-port 1/2
port group interface Ten-GigabitEthernet 1/0/49
port group interface Ten-GigabitEthernet 1/0/50
qu
interface range Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/50
undo shutdown
qu
save
irf-port-configuration active

SW2

sys
irf member 1 renumber 2     
interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
shutdown
qu
irf-port 2/1
port group interface Ten-GigabitEthernet 2/0/49
port group interface Ten-GigabitEthernet 2/0/50
qu
interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50
undo shutdown
qu
save
irf-port-configuration active
reboot

🎉六、堆叠完成后的确认结果
