步驟1. 確定IRF裝置角色，配置裝置的IRF優先順序和編號
[IRF2]irf member 1 renumber 2 //將IRF2(即SW2)的成員編號設定為2，預設為1
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
[IRF2]save //切記儲存
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.
[IRF2]quit
<IRF2>reboot //必須重啟裝置
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...
%Nov 25 22:02:11:207 2018 IRF2 DEV/5/SYSTEM_REBOOT: System is rebooting now.

[H3C]sysname IRF1
[IRF1]irf member 1 priority 32 //設定IRF1（SW1）的IRF優先順序為32，該值已經最大，保證IRF1裝置成為主裝置
[IRF1]int r te 1/0/50 to t 1/0/51
[IRF1-if-range]shu //把交換機互聯介面關閉，這是必須的一部
[IRF1-if-range]quit
[IRF1]irf-port 1/2 //設定IRF1的邏輯介面2
[IRF1-irf-port1/2]port g int te 1/0/50 //把物理介面加入邏輯介面
You must perform the following tasks for a successful IRF setup:
Save the configuration after completing IRF configuration.
Execute the "irf-port-configuration active" command to activate the IRF ports.
[IRF1-irf-port1/2]port g int te 1/0/51 //把物理介面加入邏輯介面
[IRF1-irf-port1/2]quit
[IRF1]int r te 1/0/50 to t 1/0/51
[IRF1-if-range]un sh //開啟物理介面

步驟2. Slave裝置加入物理成員介面
[IRF2]int r t 2/0/50 to t 2/0/51
[IRF2-if-range]shu //IRF2裝置重啟後關閉物理介面
[IRF2-if-range]quit
[IRF2]irf-port 2/1 //注意，特別推薦使用交叉互聯，請對比IRF1裝置，否則可能造成堆疊失敗
[IRF2-irf-port2/1]port g int t 2/0/50 //把物理介面加入邏輯介面
You must perform the following tasks for a successful IRF setup:
Save the configuration after completing IRF configuration.
Execute the "irf-port-configuration active" command to activate the IRF ports.
[IRF2-irf-port2/1]port g int t 2/0/51 //把物理介面加入邏輯介面
[IRF2-irf-port2/1]quit
[IRF2]int r t 2/0/50 to t 2/0/51
[IRF2-if-range]un shu //開啟物理介面
