网络拓扑图：

图中两台S5820交换机都分别使用万兆口50口、51口进行互联，其中1号设备、2号设备均已在拓扑图中标识清楚，1代表成员1、2代表成员2

配置步骤

1. 1号设备设定为IRF 1号成员，2号设备设定为IRF 2号成员。
2. 绑定IRF端口。
3. 激活IRF功能。
4. 检查设备是否已堆叠完成。

配置关键点

1. 1号设备关键配置如下：

   [H3C]irf member 1 renumber 1     //将1号设备设定为成员1
   Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
   [H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
   [H3C-if-range]shutdown
   [H3C-if-range]quit
   [H3C]irf-port 1/1  //将物理端口绑定到IRF端口
   [H3C-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/50
   [H3C-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/51
   [H3C-irf-port1/1]quit
   [H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
   [H3C-if-range]undo shutdown
   [H3C-if-range]quit
   [H3C]irf-port-configuration active  //激活IRF
   [H3C]save

2. 2号设备关键配置点如下：

   [H3C]irf member 1 renumber 2  //将2号设备设定为成员2
   [H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
   [H3C-if-range]shutdown
   [H3C-if-range]quit
   [H3C]irf-port 1/2  //将物理端口绑定到IRF端口
   [H3C-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/50
   [H3C-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/51
   [H3C-irf-port1/2]quit
   [H3C]int range Ten-GigabitEthernet 1/0/50 to Ten-GigabitEthernet 1/0/51
   [H3C-if-range]undo shutdown
   [H3C-if-range]quit
   [H3C]irf-port-configuration active  //激活IRF
   [H3C]save

3. 分别将成员1设备、成员2设备重启
4. 测试

   <H3C>dis irf  //查看IRF的信息，看到成员1和成员2的设备信息都在一起
   MemberID    Role    Priority  CPU-Mac       Description
   \*+1        Master  1         30bd-490a-0104
   2        Standby 1         30bd-525e-0204
   \* indicates the device is the master.
   \+ indicates the device through which the user logs in.
   The bridge MAC of the IRF is: 30bd-490a-0100
   Auto upgrade                : yes
   Mac persistent              : 6 min
   Domain ID                   : 0

   <H3C>dis irf link  //查看成员1、成员2 IRF链路的状态均为UP
   Member 1
   IRF Port  Interface                             Status

           Ten-GigabitEthernet1/0/51             UP
   2         disable                               --
   Member 2

   2         Ten-GigabitEthernet2/0/50             UP
           Ten-GigabitEthernet2/0/51             UP

   <H3C>dis irf configuration  //查看IRF的配置信息
   MemberID NewID    IRF-Port1                     IRF-Port2
   1        1        Ten-GigabitEthernet1/0/50     disable
                   Ten-GigabitEthernet1/0/51
   2        2        disable                       Ten-GigabitEthernet2/0/50
                                                 Ten-GigabitEthernet2/0/51

   <H3C>dis irf topology  //查看IRF的拓扑信息
                              Topology Info
               IRF-Port1                IRF-Port2
   MemberID    Link       neighbor      Link       neighbor    Belong To
   2           DIS        ---           UP         1           30bd-490a-0104
   1           UP         2             DIS        ---         30bd-490a-0104
   <H3C>

   至此S5820交换机的IRF已配置完成！
