最佳答案
由于网络规模迅速扩大,当前中心设备(Device A)转发能力已经不能满足需求,现需要在保护现有投资的基础上将网络转发能力提高一倍,并要求网络易管理、易维护。
图3-14 IRF典型配置组网图(BFD MAD检测方式)
· Device A处于局域网的汇聚层,为了将汇聚层的转发能力提高一倍,需要另外增加一台设备Device B。
· 鉴于IRF技术具有管理简便、网络扩展能力强、可靠性高等优点,所以本例使用IRF技术构建网络汇聚层(即在Device A和Device B上配置IRF功能),接入层设备通过聚合双链路上行。
· 为了防止万一IRF链路故障导致IRF分裂、网络中存在两个配置冲突的IRF,需要启用MAD检测功能。因为成员设备比较少,我们采用BFD MAD检测方式来监测IRF的状态。

您好,请知:
以下是IRF配置参考案例:
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
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。
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]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-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
