1. 实验目的:
- 熟悉堆叠的应用场景
- 掌握堆叠的配置方法
2. 实验拓扑
实验拓扑如图所示。

【技术要点】
现网中公司需要对交换网络扩容,需要将SW1和SW2两台设备使用业务接口进行堆叠。(华为ensp模拟器不支持堆叠,此实验使用H3C的模拟器HCL)
3. 实验步骤
1)选择需要进行堆叠的业务接口,并且将端口shutdown
SW1的配置
<H3C>system-view
System View: return to User View with Ctrl+Z.
H3C\]sysname SW1 \[SW1\]interface Ten-GigabitEthernet 1/0/50 \[SW1-Ten-GigabitEthernet1/0/50\]shutdown \[SW1-Ten-GigabitEthernet1/0/50\]quit
SW2的配置
<H3C>system-view
System View: return to User View with Ctrl+Z.
H3C\]sysname SW2 \[SW2\]interface Ten-GigabitEthernet 1/0/50 \[SW2-Ten-GigabitEthernet1/0/50\]shutdown \[SW2-Ten-GigabitEthernet1/0/50\]quit
2)将SW1配置成堆叠后的主设备,配置对应的优先级,并将业务线缆加入虚拟的堆叠口
SW1\]irf member 1 priority 30 //配置设备的堆叠成员ID为1,堆叠优先级为30 \[SW1\]irf-port 1/1 //进入虚拟堆叠口 \[SW1-irf-port1/1\]port group interface Ten-GigabitEthernet 1/0/50//将物理接口加入到堆叠口 \[SW1-irf-port1/1\]quit \[SW1\]irf-port-configuration active //激活堆叠配置 \[SW1\]interface Ten-GigabitEthernet 1/0/50 \[SW1-Ten-GigabitEthernet1/0/50\]undo shutdown //开启物理接口 \[SW1\]save //保存配置
3)将SW2业务线缆加入虚拟的堆叠线缆
SW2\]irf member 1 renumber 2 //配置堆叠成员ID为1(成员ID不能冲突) Renumbering the member ID may result in configuration change or loss. Continue?\[Y/N\]:y \[SW2\]irf-port 1/2 //进入虚拟堆叠口1/2 \[SW2-irf-port1/2\]port group interface Ten-GigabitEthernet 1/0/50//将物理接口加入到堆叠口 \[SW2-irf-port1/2\]quit \[SW2\]irf-port-configuration active //激活堆叠配置 \[SW2\]interface Ten-GigabitEthernet 1/0/50 \[SW2-Ten-GigabitEthernet1/0/50\]undo shutdown \[SW2-Ten-GigabitEthernet1/0/50\]quit \[SW2\]save
4)SW1的配置
SW1\]quit \
reboot将设备重启,自动完成堆叠。
SW2的配置
SW1\]quit \
reboot
4)实验调试
查看堆叠配置
<SW1>display irf //查看堆叠配置
MemberID Role Priority CPU-Mac Description
*+1 Master 30 0caa-192d-0104 ---
2 Standby 1 0caa-1b49-0204 ---
* indicates the device is the master.
- indicates the device through which the user logs in.
The bridge MAC of the IRF is: 0caa-192d-0100
Auto upgrade : yes
Mac persistent : 6 min
Domain ID : 0
可以看到堆叠ID为1的SW1为master,即主设备,堆叠ID为2的SW2为standby,即从设备。最终可以实现,将多台物理设备堆叠成一台逻辑设备。
