一、IRF配置思路
1.配置裝置編号
<DeviceB> system-view
[DeviceB] irf member 1 renumber 2 //更改編号
Warning: Renumbering the switch number may result in configuration change or
loss. Continue? [Y/N] :y
[DeviceB ]
< DeviceB >reboot //重新開機裝置
2.修改IRF優先級為5，建立IRF端口并綁定
<DeviceA> system-view
[DeviceA] irf member 1 priority 5 //讓其在競選Master時獲勝
//在DeviceA.上建立裝置的IRF端口2,與實體端口Ten-GigabitEthernet1/0/52綁定,并儲存配置<DeviceA> system-view
[DeviceA] interface ten-gigabitethernet 1/0/52
[DeviceA-Ten-GigabitEthernet1/0/52] shutdown
[DeviceA-Ten-GigabitEthernet1/0/52] quit
[DeviceA] irf-port 1/2
[DeviceA-irf-port1/2] port group interface ten-gigabitethernet 1/0/52
[DeviceA-irf-port1/2] quit
[DeviceA] interface ten-gigabitethernet 1/0/52
[ DeviceA-Ten-GigabitEthernet1/0/52] undo shutdown
[ DeviceA-Ten-Gigabi tEthernet1/0/52] save
<DeviceB> system-view
[DeviceB] interface ten-gigabitethernet 2/0/52
[DeviceB-Ten-Gigabi tEthernet2/0/52] shutdown
[DeviceB-Ten-GigabitEthernet2/0/52] quit
[DeviceB] irf-port 2/1
[DeviceB-irf-port2/1] port group interface ten-gigabitethernet 2/0/52[DeviceB-irf-port2/1] quit
[DeviceB] interface ten-gigabitethernet 2/0/52
[DeviceB-Ten-GigabitEthernet2/0/52] undo shutdown
[DeviceB-Ten-GigabitEthernet2/0/52] save
3.激活DeviceA的IRF端口配置
[ DeviceA-Ten-GigabitEthernet1/0/52] quit
[DeviceA] irf-port-configuration active
4.激活DeviceB的IRF端口配置
[ DeviceB-Ten-GigabitEthernet2/0/52] quit
[DeviceB] irf-port-configuration active
（兩台裝置間會進行Master競選，競選失敗的一方将會自動重新開機，重新開機完成後，IRF形成，系統名稱統一為主裝置的名稱）
二、LACP MAD檢測配置
1、建立兩個動态聚合端口,并配置trunk
[sw1]interface Bridge-Aggregation 2
[sw1-Bridge-Aggregation2]port link trunk
[sw1-Bridge-Aggregation2]port trunk permit vlan all
[sw1-Bridge-Aggregation2]link-aggregation mode dynamic
[sw1-Bridge-Aggregation2]mad enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 0]:
The assigned domain ID is: 0
MAD LACP only enable on dynamic aggregation interface.
[sw1-Bridge-Aggregation2]quit
[sw1]int Bridge-Aggregation 3
[sw1-Bridge-Aggregation3]port link trunk
[sw1-Bridge-Aggregation3]port trunk permit vlan all
[sw1-Bridge-Aggregation3]link-aggregation mode dynamic
[sw1-Bridge-Aggregation3]mad enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 0]:
The assigned domain ID is: 0
MAD LACP only enable on dynamic aggregation interface.
[sw1-Bridge-Aggregation3]quit
2.建立相應的聚合端口組，并配置trunk
[SW3]interface Bridge-Aggregation 2
[SW3-Bridge-Aggregation2]port link trunk
[SW3-Bridge-Aggregation2]port trunk permit vlan all
[SW3-Bridge-Aggregation2]link-aggregation mode dynamic
[SW3-Bridge-Aggregation2]quit
3、在聚合接口上添加成員，并配置trunk
[sw1]interface GigabitEthernet 1/0/1
[sw1-GigabitEthernet1/0/1]port link-type trunk
[sw1-GigabitEthernet1/0/1]port trunk permit vlan all
[sw1-GigabitEthernet1/0/1]port link-aggregation group 2 //加入2組（每個裝置對應的組号）
[sw1-GigabitEthernet1/0/1]quit
（裝置上的每一個聚合接口上都要添加成員）
三、IRF和MAD配置的顯示和維護資訊
1、檢視裝置的IRF配置資訊
[sw1]display irf
MemberID Role Priority CPU-Mac Description
*+1 Master 5 2c63-c480-0304 ---
2 Standby 1 2c63-c8c5-0404 ---
--------------------------------------------------
* indicates the device is the master.
+ indicates the device through which the user logs in.
The bridge MAC of the IRF is: 2c63-c480-0300
Auto upgrade : yes
Mac persistent : 6 min
Domain ID : 0
| 字段 | 描述 |
|---|---|
| Switch | 本IRF中成員裝置的編号（如果編号前帶"*"，表示該裝置是Master裝置；如果編号前帶"+"，表示該裝置是使用者目前登入的、正在操作的裝置） |
| Role | 本IRF中成員裝置的角色，取值可能如下：Slave: 備用裝置；Master: 主用裝置；Slave Wait: 正在加入IRF；Loading: 正在自動加載系統啟動檔案 |
