IRF配置思路
网络括谱图

主 Ten-GigabitEthernet  1/0/49   Ten-GigabitEthernet  1/0/50  Ten-GigabitEthernet  1/0/51

备 Ten-GigabitEthernet  2/0/49   Ten-GigabitEthernet  2/0/50  Ten-GigabitEthernet  2/0/51

思路

主

1 利用console线进入设备的命令行页面去更改设备的名字 （华三设备默认的用户名密码:admin/admin）
[H3C]sysname  master
[H3C]sysname  backup
2 主的配置思路
2.1 设置优先级 确认该设备是主设备
[master]irf member  1 priority  15

2.2 将设备IRF连接的接口shutdown
[master]interface  range  Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/51

[master-if-range]shutdown

2.3 退出
quit

2.4 创建虚拟IRF接口
[master]irf-port 1/1

2.5 将接口增加到IRF接口
[master-irf-port1/1]port  group  interface Ten-GigabitEthernet  1/0/49

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

[master-irf-port1/1]port  group  interface Ten-GigabitEthernet  1/0/51

2.6 退出
quit

2.7  将对应对接口开启来
[master]interface  range  Ten-GigabitEthernet 1/0/49 to Ten-GigabitEthernet 1/0/51

[master-if-range]un shutdown

2.8 激活IRF
[master]irf-port-configuration  active

2.9 保存
save

2.10  退出
quit

2.11  重启
reboot

备

3.1 将设备成员改为2
[backup]irf member 1 renumber  2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y

3.2  保存
[backup]save

3.3 退出
[backup] quit

3.4 重启
[backup]reboot

3.2 进入接口
[backup]interface  range  Ten-GigabitEthernet 2/0/49 to Ten-GigabitEthernet 2/0/
51
[backup-if-range]shutdown

3.3 退出
quit

3.4 创建IRF虚拟接口
[backup]irf-port 2/2

3.5 将对应的接口增加进去
[backup-irf-port2/2]port  group  interface  Ten-GigabitEthernet 2/0/49

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

[backup-irf-port2/2]port  group  interface  Ten-GigabitEthernet 2/0/51

3.6 退出
[backup-irf-port2/2]quit
[backup]

3.7  将接口undo showdown
[backup]interface  range  Ten-GigabitEthernet  2/0/49 to  Ten-GigabitEthernet 2/0/51

[backup-if-range]undo  shutdown

3.8 退出
quit

3.9 保存
<backup>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.

3.10 激活
[backup]irf-port-configuration  active
