华三H3C交换机如何配置三个交换机堆叠IRF虚拟化

华三交换机如何用三个交换机配置IRF堆叠（环形和链形结构）

一，三个交换机配置环形IRF

组网交换机如下图，

SWA，SWB，SWC三台交换机环形结构组建IRF，SWA作为Master

------------------------------------------------------------------------------------------

1.1，SWA配置

[SWA]irf member 1 priority 20 //配置优先级为20，确保为master

先把FortyGigE 1/0/53 和 FortyGigE 1/0/54关闭

[SWA]interface range FortyGigE 1/0/53 to FortyGigE 1/0/54

[SWA-if-range]shutdown

创建一个IRF虚拟接口1/1

[SWA]irf-port 1/1

[SWA-irf-port1/1]port group interface FortyGigE 1/0/53 //加入虚拟接口

创建一个IRF虚拟接口1/2

[SWA]irf-port 1/2

[SWA-irf-port1/2]port group interface FortyGigE 1/0/54 //加入虚拟接口

再把FortyGigE 1/0/53 和 FortyGigE 1/0/54端口undoshutdown

[SWA]interface range FortyGigE 1/0/53 to FortyGigE 1/0/54

[SWA-if-range]undo shutdown

保存配置。

[SWA]save force //一定要保存好配置

---------------------------------------------------------------------------------------------

SWB配置

[SWB]irf member 1 renumber 2 //重新编号为2

保存配置后，重启交换机

[SWB]save force

<SWB>reboot

待交换机重启后，把FE53和FE54接口关闭

[SWB]interface range FortyGigE 2/0/53 to FortyGigE 2/0/54

[SWB-if-range]shutdown

[SWB]irf-port 2/1 //创建虚拟接口2/1

[SWB-irf-port2/1]port group interface FortyGigE 2/0/53 //绑定接口

[SWB]irf-port 2/2 //创建虚拟接口2/2

[SWB-irf-port2/2]port group interface FortyGigE 2/0/54 //绑定接口

[SWB]interface range FortyGigE 2/0/53 to FortyGigE 2/0/54 //把接口再undo shutdown

[SWB-if-range]undo shutdown

[SWB]save force //保存配置

--------------------------------------------------------------------------------------

SWC配置

[SWC]irf member 1 renumber 3 //重新编号为3

保存配置后重启交换机

[SWC]save force

<SWC>reboot

关闭接口

[SWC]interface range FortyGigE 3/0/53 to FortyGigE 3/0/54

[SWC-if-range]shutdown

[SWC]irf-port 3/1 创建虚拟接口3/1

[SWC-irf-port3/1]port group interface FortyGigE 3/0/53 //绑定接口

[SWC]irf-port 3/2 创建虚拟接口3/2

[SWC-irf-port3/2]port group interface FortyGigE 3/0/54 //绑定接口

[SWC]interface range FortyGigE 3/0/53 to FortyGigE 3/0/54 //把接口undo shutdown

[SWC-if-range]undo shutdown

[SWC]save force //一定保存好配置

--------------------------------------------------------------------------------------------------

激活三交换机IRF，先激活SWA，然后激活SWB和SWC。

[SWA]irf-port-configuration active

[SWB]irf-port-configuration active

[SWC]irf-port-configuration active

-------------------------------------------------------------------------------

使用命令display irf查看配置

二，三个交换机链形配置IRF

SWA配置

[SWA]irf member 1 priority 10 //配置优先级为10，确保为master

[SWA]interface Ten-GigabitEthernet 1/0/50 //把要加入的接口关闭

[SWA-Ten-GigabitEthernet1/0/50]shutdown

创建虚拟接口，并绑定端口

[SWA]irf-port 1/1

[SWA-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/50

把端口undo shutdown

[SWA]interface Ten-GigabitEthernet 1/0/50

[SWA-Ten-GigabitEthernet1/0/50]undo shutdown

[SWA]save force //一定保存好配置

[SWA]irf-port-configuration active //激活irf

-----------------------------------------------------------------------------------

SWB配置

[SWB]irf member 1 renumber 2 ////重新编号为2

[SWB]sa f //保存配置后重启交换机

<SWB>reboot

交换机重启后把端口shutdown

[SWB]interface Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50

[SWB-Ten-GigabitEthernet2/0/49]shutdown

创建虚拟接口后绑定端口

[SWB]irf-port 2/2

[SWB-irf-port2/2]port group interface Ten-GigabitEthernet 2/0/49

[SWB]irf-port 2/1

[SWB-irf-port2/1]port group interface Ten-GigabitEthernet 2/0/50

[SWB]interface range Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/50

[SWB-if-range]undo shutdown

[SWB]save force //保存配置

[SWB]irf-port-configuration active //激活irf

----------------------------------------------------------------------------------------------------

SWC配置

[SWC]irf member 1 renumber 3 //重新编号为3

[SWC]save force //保存配置后重启

<SWC>reboot

交换机重启后，把要加入的端口shutdown

[SWC]interface Ten-GigabitEthernet 3/0/49

[SWA-Ten-GigabitEthernet3/0/49]shutdown

创建虚拟接口后绑定端口

[SWC]irf-port 3/2

[SWC-irf-port3/2]port group interface Ten-GigabitEthernet 3/0/49

[SWC]interface Ten-GigabitEthernet 3/0/49

[SWA-Ten-GigabitEthernet3/0/49]undo shutdown

[SWC]save force //保存配置

[SWC]irf-port-configuration active //激活irf

使用命令display irf查看irf配置信息
