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。

 

二.配置了堆叠后的设备链路验的配置

 

 

 

 

SW1]dis irf
MemberID    Role    Priority  CPU-Mac         Description
  *1        Master  1         2e92-6b04-0104  ---
  +2        Standby 1         2e92-832c-0204  ---

 

• IRF-SW的配置链路聚合
  

   链路聚合先配置物理端口加入聚合组，再做聚合组vlan、trunk划分等设置。

//在IRF-SW上配置，将SW1的g0/1与SW2的g0/1做聚合
[IRF-SW]interface Bridge-Aggregation 1  //创建聚合口

[TRF-SW1]port link-type trunk   //接口类型配置为Trunk
[TRF-SW1]port trunk permit vlan 10  //Trunk接口允许VLAN10通过

[IRF-SW-Bridge-Aggregation1]int g1/0/1 //进入物理接口(第一台核心交换机的物理接口)
[IRF-SW-GigabitEthernet1/0/1]port link-aggregation group 1 //将物理接口加入聚合口 
[IRF-SW-GigabitEthernet1/0/1]int g2/0/1 //进入物理接口（第二台核心的物理接口因为是做了堆叠修改为了是2/0/1开头的） 
[IRF-SW-GigabitEthernet2/0/1]port link-aggregation group 1 //将物理接口加入聚合口
[IRF-SW-GigabitEthernet2/0/1]display link-aggregation summary //检查两个端口是否都被加入到聚合口，简写dis link-a su //同样方法将SW1的g0/2与SW2的g0/2做聚合

//在IRF-SW上配置，将SW1的g0/1与SW2的g0/1做聚合
[IRF-SW]interface Bridge-Aggregation 2  //创建聚合口

[TRF-SW1]port link-type trunk   //接口类型配置为Trunk
[TRF-SW1]port trunk permit vlan 10  //Trunk接口允许VLAN10通过

[IRF-SW-Bridge-Aggregation1]int g1/0/2 //进入物理接口(第一台核心交换机的物理接口)
[IRF-SW-GigabitEthernet1/0/2]port link-aggregation group 1 //将物理接口加入聚合口

[IRF-SW-GigabitEthernet1/0/2]int g2/0/2 //进入物理接口（第二台核心的物理接口因为是做了堆叠修改为了是2/0/1开头的）

[IRF-SW-GigabitEthernet2/0/2]port link-aggregation group 1 //将物理接口加入聚合口

[IRF-SW-GigabitEthernet2/0/2]display link-aggregation summary //检查两个端口是否都被加入到聚合口，简写dis link-a su

 

 

 

接入层的交换机配置

• SW3把连接与核心交换机的接口加入VLAN10（配置trunk模式）

在SW3上将g0/1与g0/2做聚合 
[SW3]int Bridge-Aggregation 1

[SW3]int Bridge-Aggregation 1  //创建聚合口
[SW3-Bridge-Aggregation1]port link-type trunk   //接口类型配置为Trunk
[SW3-Bridge-Aggregation1]port trunk permit vlan 10  //Trunk接口允许VLAN10通过

[SW3-Bridge-Aggregation1]int g1/0/1 
[SW3-GigabitEthernet1/0/1]port link-aggregation group 1
[SW3-Bridge-Aggregation1]int g1/0/2
[SW3-GigabitEthernet1/0/2]port link-aggregation group 1 
[SW3-GigabitEthernet1/0/2]qu //同样方法在SW4上将g0/1与g0/2做聚合 

 

• SW3把连接PC的接口加入VLAN10

 

[SW3]vlan 10
[SW3-vlan10]port g1/0/3
[SW3-vlan10]qu

//同样方法将SW4接PC端的接口划分到VLAN10

 

• 将SW4与核心交换机聚合端口配置为Trunk类型

 

[SW3]int Bridge-Aggregation 2 //创建聚合口
[SW3-Bridge-Aggregation1]port link-type trunk   //接口类型配置为Trunk
[SW3-Bridge-Aggregation1]port trunk permit vlan 10  //Trunk接口允许VLAN10通过
[SW3]dis link-aggregation summary  /检查聚合口

//同样方法将SW4聚合端口配置为Trunk类型

//在IRF-SW上将两个聚合口均配置为Trunk类型，并配置放行VLAN10

[IRF-SW]vlan 10  //划分VLAN10
[IRF-SW]int Bridge-Aggregation 2  //进入1聚合接口
[IRF-SW-Bridge-Aggregation1]port link-type trunk   //聚合接口1配置为Trunk类型
[IRF-SW-Bridge-Aggregation1]port trunk permit vlan 10  //放行VLAN10
[IRF-SW-Bridge-Aggregation1]qu
[IRF-SW]dis link-aggregation summary  //检查聚合接口

• SW4把连接PC的接口加入VLAN10

[SW3]vlan 10
[SW3-vlan10]port g1/0/3
[SW3-vlan10]qu
