- 修改 IRF 优先级为 32（默认是 1，数字越大越优先成为 Master）
[Leaf-01] irf member 1 priority 32 - 进入准备用于堆叠的物理接口，必须先手动关闭（Shutdown）
[Leaf-01] interface range Ten-GigabitEthernet 1/0/51 to Ten-GigabitEthernet 1/0/52
[Leaf-01-if-range] shutdown
[Leaf-01-if-range] quit - 创建 IRF 逻辑端口 1/1，并将物理端口绑定进去
[Leaf-01] irf-port 1/1
[Leaf-01-irf-port1/1] port group interface Ten-GigabitEthernet 1/0/51
[Leaf-01-irf-port1/1] port group interface Ten-GigabitEthernet 1/0/52
[Leaf-01-irf-port1/1] quit - 重新开启物理端口
[Leaf-01] interface range Ten-GigabitEthernet 1/0/51 to Ten-GigabitEthernet 1/0/52
[Leaf-01-if-range] undo shutdown
[Leaf-01-if-range] quit - 保存配置（这步很重要，激活前先保存）
[Leaf-01] save force - 激活 IRF 端口配置
[Leaf-01] irf-port-configuration active - 将成员编号由 1 改为 2
[Leaf-02] irf member 1 renumber 2
注意：此时系统会提示你重启生效。直接在用户视图下保存并重启：
[Leaf-02] quit
save force
reboot - 此时接口已经变成了 2/0/xx。进入物理端口并关闭
[Leaf-02] interface range Ten-GigabitEthernet 2/0/51 to Ten-GigabitEthernet 2/0/52
[Leaf-02-if-range] shutdown
[Leaf-02-if-range] quit - 创建 IRF 逻辑端口 2/2（规则：成员号/端口号，本端是2号设备，连对端1号，通常建2/2）
[Leaf-02] irf-port 2/2
[Leaf-02-irf-port2/2] port group interface Ten-GigabitEthernet 2/0/51
[Leaf-02-irf-port2/2] port group interface Ten-GigabitEthernet 2/0/52
[Leaf-02-irf-port2/2] quit - 重新开启物理端口
[Leaf-02] interface range Ten-GigabitEthernet 2/0/51 to Ten-GigabitEthernet 2/0/52
[Leaf-02-if-range] undo shutdown
[Leaf-02-if-range] quit - 保存配置
[Leaf-02] save force - 激活 IRF 端口配置（激活后，Leaf-02 检测到对端，会自动重启并加入堆叠）
[Leaf-02] irf-port-configuration active
