1. IRF简介
IRF它的核心思想是将多台设备连接在一起，进行必要的配置后，虚拟化成一台设备
1.1 实验环境
H3C模拟器版本
1.2 添加交换机
1.3 添加连接线
1.4 启动设备
1.5 修改设备名称
SW1：
system-view
[H3C]sysname SW1
[SW1]
SW2：
system-view
[H3C]sysname SW2
[SW2]
1.6 关闭IRF物理端口
SW1：
[SW1]interface Ten-GigabitEthernet1/0/49
[SW1-Ten-GigabitEthernet1/0/49]shutdown
[SW1-Ten-GigabitEthernet1/0/49]quit
SW2：
[SW2]interface Ten-GigabitEthernet1/0/49
[SW2-Ten-GigabitEthernet1/0/49]shutdown
[SW2-Ten-GigabitEthernet1/0/49]quit
1.7 设置IRF域编号
SW1：
[SW1]irf domain 10
SW2：
[SW2]irf domain 10
1.8 设置member成员编号
SW1：
[SW1]irf member 1 renumber 1
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
SW2：
[SW2]irf member 1 renumber 2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
1.9 配置IRF端口并与物理端口绑定
如果SW1使用 1/1，那SW2只能使用1/2
SW1：
[SW1]irf-port 1/1
[SW1-irf-port1/1]port group interface Ten-GigabitEthernet 1/0/49
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.
[SW1-irf-port1/1]quit
SW2：
[SW2]irf-port 1/2
[SW2-irf-port1/2]port group interface Ten-GigabitEthernet 1/0/49
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.
[SW2-irf-port1/2]quit
1.10 开启IRF物理端口，保存配置
SW1：
[SW1]interface Ten-GigabitEthernet1/0/49
[SW1-Ten-GigabitEthernet1/0/49]un
[SW1-Ten-GigabitEthernet1/0/49]undo shu
[SW1-Ten-GigabitEthernet1/0/49]undo shutdown
[SW1-Ten-GigabitEthernet1/0/49]quit
[SW1]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):
Validating file. Please wait...
Saved the current configuration to mainboard device successfully.
SW2：
[SW2]interface Ten-GigabitEthernet 1/0/49
[SW2-Ten-GigabitEthernet1/0/49]undo shutdown
[SW2-Ten-GigabitEthernet1/0/49]quit
[SW2]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):
Validating file. Please wait...
Saved the current configuration to mainboard device successfully.
1.11 激活IRF端口下的配置
SW1：
[SW1]irf-port-configuration active
SW2：
[SW2]irf-port-configuration active
重启SW2
1.12 查看irf状态
SW1是Master，SW2是Standby
*表示Master设备
+表示当前通过那台设备登陆
2. IRF角色选举
确定成员设备角色为主设备或从设备的过程称为角色选举。角色选举会在以下情况下进行：IRF 建立、主设备离开或者故障、两个 IRF 合并等。
角色选举规则如下：
- 当前主设备优先，IRF 不会因为有新的成员设备加入而重新选举主设备。不过，当 IRF形成时，因为没有主设备，所有加入的设备都认为自己是主设备，则继续下一条规则的比较。
- 成员优先级大的优先。如果优先级相同，则继续下一条规则的比较。
- 系统运行时间长的优先。在 IRF 中，成员设备启动时间间隔精度为 10 分钟，即 10分钟之内启动的设备，则认为它们是同时启动的，则继续下一条规则的比较。
- CPU MAC 小的优先。通过以上规则选出的最优成员设备即为主设备，其它成员设备则均为从设备。
2.1 更改优先级改变master
默认优先级为1，更改后并不会重新选举，需要member 1重启（谨慎）
[SW1]irf member 2 priority 10
2.2 member 2成为Master
3. 案例
拓扑
3.1 SW1
#irf区域设置
[H3C]sysname SW1
