其实堆叠吧，也算是一种虚拟化技术了。你可以理解为把多台交换机虚拟化成一台大的交换机去使用。
本期就与大家分享一下如何用H3C模拟器（HCL）来配置交换机irf。
01
实验环境搭建
接下来，分别启动两台交换机
02
基础配置
分别给每台交换机修改设备名（这个不是必须的配置，我是为了给大家演示一下，作完堆叠后，SW2设备名也会自动更改）
先将互联的接口shutdown一下：
[SW1]int Ten-GigabitEthernet 1/0/49
[SW1-Ten-GigabitEthernet1/0/49]shut
[SW1-Ten-GigabitEthernet1/0/49]quit
[SW1]
[SW2]int Ten-GigabitEthernet 1/0/49
[SW2-Ten-GigabitEthernet1/0/49]shut
[SW2-Ten-GigabitEthernet1/0/49]quit
[SW2]
03
irf堆叠关键配置
[SW1]irf domain 100
[SW1]irf member 1 renumber 1
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
[SW1]
[SW1]irf-port 1/1
[SW1-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/49
[SW1-irf-port1/1]quit
[SW1]
[SW1]irf-port-configuration active
[SW2]irf domain 100
[SW2]irf member 1 renumber 2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
[SW2]
[SW2]irf-port 1/2
[SW2-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/49
[SW2-irf-port1/2]quit
[SW2]
[SW2]irf-port-configuration active
解释：irf member 1 renumber 2
这个就是把原来接口卡编号重新规划命名，两台交换机不能一样。
irf member 1 renumber 2，即把上图红色圈起来的接口卡编号由1改为2.
由于SW1是1，那SW2需要区别开，所以改成2，当然你也可以改成其他的，一般建议数字连续吧。
04
保存，重启，堆叠生效
现在我们把接口打开undo shutdown一下：
[SW1]int Ten-GigabitEthernet 1/0/49
[SW1-Ten-GigabitEthernet1/0/49]undo shut
[SW1-Ten-GigabitEthernet1/0/49]quit
[SW1]
[SW2]int Ten-GigabitEthernet 1/0/49
[SW2-Ten-GigabitEthernet1/0/49]undo shut
[SW2-Ten-GigabitEthernet1/0/49]quit
[SW2]
堆叠生效之前，我们来做个小测试，在SW1，创建vlan 100，然后在SW2查看：
SW2上未看到vlan 100，只有默认VLAN1：
接下来，记得保存一下再重启，观察堆叠是否生效了：
<SW1>save
The current configuration will be written to the device. Are you sure? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
Validating file. Please wait...
Saved the current configuration to mainboard device successfully.
<SW1>reboot
Start to check configuration with next startup configuration file, please wait.........DONE!
This command will reboot the device. Continue? [Y/N]:Y
Now rebooting, please wait...
%Jan 19 00:08:30:352 2021 SW1 DEV/5/SYSTEM_REBOOT: System is rebooting now.
<SW2>save
The current configuration will be written to the device. Are you sure? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
Validating file. Please wait...
Saved the current configuration to mainboard device successfully.
<SW2>reboot
Start to check configuration with next startup configuration file, please wait.........DONE!
This command will reboot the device. Continue? [Y/N]:Y
Now rebooting, please wait...
%Jan 19 00:06:31:073 2021 SW2 DEV/5/SYSTEM_REBOOT: System is rebooting now.
05
验证查看
重启后，你会发现SW2的设备名自动修改为SW1了：
也间接说明堆叠配置成功了，我们也可以查一下堆叠状态：
现在我们可以在SW1创建一个vlan 200，看看原先所谓的SW2是不是也自动看到这个配置：
在原先SW2 可以看到这个配置了：
到这里，堆叠就基本配置完成了。
06
修改irf优先级可改变master
在原先sw2上修改设备名：
在原先sw2上修改irf优先级，比如这里修改到最高32：
在原先sw2那台保存配置，重启生效：
<SW2>save
The current configuration will be written to the device. Are you sure? [Y/N]:Y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
flash:/startup.cfg exists, overwrite? [Y/N]:Y
Validating file. Please wait...
Saved the current configuration to mainboard device successfully.
Slot 2:
Save next configuration file successfully.
<SW2>
<SW2>reboot
Start to check configuration with next startup configuration file, please wait.........DONE!
This command will reboot the device. Continue? [Y/N]:Y
Now rebooting, please wait...
%Jan 19 00:18:24:890 2021 SW2 DEV/5/SYSTEM_REBOOT: System is rebooting now.
SW1自动重启：
重启后，你会发现原先SW2那台变成Master了，所以优先级高的，就是Master：
二台交换机堆叠
1.二台交换机的堆叠实验拓扑
irf区域设置为10，IRFSW1为member 1，优先级设置为10；IRFSW2为member 2，优先级保持默认 1，最大的优先级为32.
实验配置及命令
IRFSW1：
irf 区域设置，并设置member 1的优先级。（默认编号也是1，最大是32）
[IRFSW1]irf domain 10
[IRFSW1]irf member 1 priority 10
先关闭端口，然后创建irf-port 1/1（member号/逻辑口编号），然后将物理口加入，再开启刚关闭的端口。
[IRFSW1]interface range FastEthernet 1/0/53 to FastEthernet1/0/54
[IRFSW1-if-range]shutdown
[IRFSW1]irf-port 1/1
[IRFSW1-irf-port1/1]port group interface FastEthernet 1/0/53
[IRFSW1-irf-port1/1]port group interface FastEthernet 1/0/54
[IRFSW1]interface range FastEthernet 1/0/53 to FastEthernet1/0/54
[IRFSW1-if-range]undo shutdown
配置结果
IRFSW2：
更改成员编号后需要保存配置后，重启使其生效。次时端口号变为2/0/50,2/0/51…
[IRFSW2]irf domain 10
[IRFSW2]irf member 1 renumber 2
<IRFSW2>save
The current configuration will be written to the device. Are you sure? [Y/N]:y
Please input the file name(*.cfg)[flash:/startup.cfg]
(To leave the existing filename unchanged, press the enter key):
Validating file. Please wait...
Saved the current configuration to mainboard device successfully.
<IRFSW2>reboot
这步和IRFSW1差不多，但是有一点很重要，特别是对多层堆叠：
irf-port 后面跟的1/1,2/2不是随便弄的，前者（数字）是交换机的成员编号，后者是成员编号对应的逻辑口号，每台只有1,2两个，你可以是n/1，n/2，但是如果你是n/1的话，那你下一个就只能是n+1/2，如果是n/2就和n/1配对，不可以两个都是1或者都是2。
[IRFSW2]interface range FastEthernet 2/0/53 to FastEthernet 2/0/54
[IRFSW2-if-range]shutdown
[IRFSW2]irf-port 2/2
[IRFSW2-irf-port2/2]port group interface FastEthernet 2/0/53
[IRFSW2-irf-port2/2]port group interface FastEthernet 2/0/54
[IRFSW2]interface range FastEthernet 2/0/53 to FastEthernet 2/0/54
[IRFSW2-if-range]undo shut
[IRFSW2-if-range]undo shutdown
配置结果
启动配置：
[IRFSW2]irf-port-configuration active
<IRFSW2>reboot
<IRFSW1>reboot
成功以后每台设备的名称会自动变成主设备的名称。
