1.irf堆叠介绍
IRF（Intelligent Resilient Framework，智能弹性架构）是 H3C 自主研发的软件虚拟化技术，通过
将多台设备虚拟为一台设备，可以简化网络拓扑，提高管理效率，并能提供 1:N 的设备级备份，帮
助您实现业界领先的企业网、数据中心汇聚/核心层解决方案。
硬件限制
S5820V2 和 S5830V2 系列交换机不但可以与本系列内的交换机建立 IRF，而且这两个系列的设备
之间也能够建立 IRF，但都不能与其它系列的产品建立 IRF。
软件限制
参与组建 IRF 的 S5820V2&S5830V2 系列交换机必须使用相同的软件版本
连接及端口限制
S5820V2-52Q/S5820V2-52QF/S5820V2-54QS-GE 交换机上的所有 10GE 以太网口、SFP+口或
QSFP+口以及 S5830V2-24S 交换机上的所有 SFP+口都可以用于 IRF 连接。如果选择 10GE 以太
网口或 SFP+口作为 IRF 物理端口，需要注意的是：
• S5820V2-52QF/S5830V2-24S 设备上的 SFP+口根据端口编号进行分组，从编号 1 开始，按
端口编号由小到大的顺序，每4个SFP+口分为一组。同一组中的所有端口用途必须相同，即
必须同时作为普通业务端口或 IRF 物理端口。
• S5820V2-52Q 设备上的 10GE 以太网口根据端口编号进行分组，从编号 1 开始，按端口编号
由小到大的顺序，每 4 个 10GE 以太网口分为一组。同一组中的所有端口用途必须相同，即
必须同时作为普通业务端口或 IRF 物理端口。
• S5820V2-54QS-GE设备上的 4个 SFP+口用途必须相同，即必须同时作为 IRF物理端口或普
通业务端口。
• 在将某个 10GE 以太网口或 SFP+口与 IRF 端口进行绑定或取消绑定之前，必须先对该接口所
在组内的所有接口执行 shutdown 操作；在完成绑定或取消绑定操作后，再对同组内所有接
口执行 undo shutdown 操作。使用接口批量配置功能可以更快捷的完成以上操作。
看完介绍，我再举个例子具体讲解下irf是如何配置的
2. 配置举例
首先我们先确认一些信息
使用的堆叠口为XG1/0/49 到 XG1/0/52
左边的设备设置member 号为1使用irf端口1-1
右边的设备设置member 号为2使用irf端口2-2
左边的设备irf优先级为32作为主设备，右边的设备irf优先级为1作为备用设备
好的，我们先看下没有做irf前设备时啥样的：
在左边的设备上敲dis irf 查看 irf信息
-------------------------------------------------------------------------------------------------------------------------------
[H3C-Ten-GigabitEthernet1/0/51]dis irf
MemberID Role Priority CPU-Mac Description
*+1 Master 1 58ab-818c-0104 ---
--------------------------------------------------
* indicates the device is the master.
+ indicates the device through which the user logs in.
The bridge MAC of the IRF is: 58ab-818c-0100
Auto upgrade : yes
Mac persistent : 6 min
Domain ID : 0
------------------------------------------------------------------------------------------------------------------------------
memberid就是设备的member号，member号决定了端口号
交换机的端口命名格式： 接口类型/ 框号/插槽号/端口号
当member号发生改变时，对应端口的框号就会发送改变
Role下面写的时Master代表时主设备的意思，与之对应的是Standby备用设备
当设备没有做irf时每台设备都会宣称自己时master主设备，当irf配置生效后，同一irf组中只用优先级最大的设备才会宣传自己时master ，其余设备会宣传自己时Standby备用设备
我们可以先看下左边设备上的端口是否包含右边设备的端口

只能看到自己的端口信息
现在配置irf （注意配置前需要将堆叠线拆除）
就像这样
左边的交换机的配置

---------------------------------------------------------------------------------------------------------------------------------
#此时左边交换机上的irf配置已经做完了
具体的配置命令脚本我会在结尾出分享出来，请各位读者耐心阅读，谢谢！！！
我们再来配置右边的交换机
首先我们在右边交换机上配置如下命令将其irf成员id变成2
--------------------------------------------------------------------------------------------------------------------------------
[H3C]irf member 1 renumber 2
#首先我们将当前的irf成员id1重命名为2
Renumbering the member ID may result in configuration change or loss. Continue?[Y/N]:y
#提示：重新编号成员ID可能会导致配置更改或丢失。继续？，我们输入y即可
[H3C]quit
#退出系统视图
#重启设备
-------------------------------------------------------------------------------------------------------------------------
此时重启完设备后irf 成员id就会变成2
我们查看下重启后的irf信息，发现irf成员id变成2
--------------------------------------------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------------------------------------------------
好的，此时irf配置我们已经全部做完了，将堆叠口的万兆尾纤插上后，右边的交换机（也就时我们计划作为备用设备的那台交换机）就会重启，重启完成后堆叠就成功了。
好的，我们再左边交换机上查看配置信息
-------------------------------------------------------------------------------------------------------------------------------

此时我们可以看到有两个设备了，
一个的member id 为1 优先级为32 是（master）主设备
另一个的member id 为2 优先级为1 是(standby)备用设备
星号标识的是master（主设备）
加号标识的是当前登陆的设备
也就是说我们当前登陆的左边的这台交换机是主设备
我们再来看 下是否能在左边设备上看到右边设备上的端口
