H3C交换机IRF典型配置指导
IRF2基本配置
实验1 IRF 2基本配置1.1 实验内容与目标完成本实验，您应该能够：● 掌握IRF 2链形堆叠的基本配置● 掌握IRF 2环形堆叠的基本配置● 掌握IRF 2的基本维护1.2 实验组网图图1-1 链形堆叠实验组网图如图1-1所示。
2台交换机通过2条堆叠电缆连接并形成IRF 。
图1-2 环形堆叠实验组网图 如图1-2所示。
3台交换机通过3条堆叠电缆首尾相连并形成IRF 。
1.3 实验设备和器材本实验所需之主要设备器材如表1-1所示。

步骤一：设备初始化检查设备的软件版本及配置信息，确保各设备软件版本符合要求，所有配置为初始状态。
如果配置不符合要求，请在用户模式下擦除设备中的配置文件，然后重启设备以使系统采用缺省的配置参数进行初始化。
以上步骤可能会用到以下命令：<Sysname> display version<Sysname> reset saved-configuration<Sysname> reboot步骤二：规划并配置IRF成员编号规划Device A的IRF成员编号是1，Device B的成员编号是2。
所以，需要在Device A 上保留缺省编号，不需要进行配置；而在Device B上将设备的成员编号修改为2。
在Device B上的配置和显示信息如下：<Sysname> system-view[Sysname] irf member 1 renumber 2Warning: Renumbering the switch number may result in configuration change or loss.Continue? [Y/N]:y[Sysname]然后将两台设备断电，按图1-1所示连接IRF链路，然后再将两台设备上电。
H3C IRF配置典型案例
H3C IRF配置典型案例●进入系统模式●切换IRF模式●配置成员编号●配置成员优先级●配置IRF端口●使能BFD MAD检测●使能LACP MAD检测●配置保留端口●手动恢复处于Recovery 状态的设备●重定向到指定的Slave 设备●IRF 显示和维护●配置举例（BFD/LACP MAD）1.进入系统模式2.切换IRF模式3.配置成员编号注:配置完成员编号后需要重启该设备。
4.配置成员优先级IRF2配置前应该将接口手工SHUT（没连线都不行）；12500系统默认都是SHUT的，95E以下必须手工SHUT5.配置IRF端口IRF2端口配置后应该将接口手工undo shutdown；然后关闭电源，连接IRF线缆，重启，IRF 形成。
6.使能BFD MAD检测注:此项与弟7项LACP MAD检测只能二选一，一般情况下使用BFD MAD检测。
7.使能LACP MAD检测8.配置保留端口9.手动恢复处于Recovery 状态的设备注:缺省状态下设备会自动恢复，只有Master设备产生故障且无法自动恢复时才进行手动恢复，正常配置中无须配置此项。
10.重定向到指定的Slave 设备注:此命令用于配置备用主控板，如: “<系统名-Slave#成员编号/槽位号>”，例如“<Sysname-Slave#1/0>”，正常配置中无须配置此项。
11.IRF 显示和维护12.配置举例一．IRF典型配置举例（BFD MAD检测方式）1. 组网需求由于网络规模迅速扩大，当前中心交换机（Device A）转发能力已经不能满足需求，现需要在保护现有投资的基础上将网络转发能力提高一倍，并要求网络易管理、易维护。
2. 组网图图1-1IRF典型配置组网图（BFD MAD检测方式）3. 配置思路为了减少IRF形成过程中系统重启的次数，可以在独立运行模式下预配置IRF端口、成员编号、以及成员优先级，配置保存后切换运行模式到IRF模式，可直接与其它设备形成IRF。

典型配置举例一IRF检测方式）1.1.1 IRF典型配置举例（LACP MAD 1. 组网需求现的接入需求。
由于公司人员激增，接入层交换机提供的端口数目已经不能满足PC 需要在保护现有投资的基础上扩展端口接入数量，并要求网络易管理、易维护。
组网图2.典型配置组网图（LACP MAD1-13 IRF检测方式）图3. 配置思路Device A提供的接入端口数目已经不能满足网络需求，需要另外增加一台设备?Device B。
（本文以两台设备组成IRF为例，在实际组网中可以根据需要，将多台设备组成IRF，配置思路和配置步骤与本例类似）鉴于第二代智能弹性架构IRF技术具有管理简便、网络扩展能力强、可靠性高等?优点，所以本例使用IRF技术构建接入层（即在Device A和Device B上配置IRF功能）。
为了防止万一IRF链路故障导致IRF分裂、网络中存在两个配置冲突的IRF，需?要启用MAD 检测功能。
因为接入层设备较多，我们采用LACP MAD检测。
4. 配置步骤为便于区分，下文配置中假设IRF形成前Device A的系统名称为DeviceA，Device B的系统名称为Device B；中间设备Device C的系统名称为DeviceC。
(1)配置设备编号# Device A保留缺省编号为1，不需要进行配置。
2上将设备的成员编号修改为Device B在#<DeviceB> system-view[DeviceB] irf member 1 renumber 2Warning: Renumbering the switch number may result in configuration change or loss. Continue? [Y/N]:y [DeviceB](2)将两台设备断电后，按图1-13所示连接IRF链路，然后将两台设备上电。
# 在Device A上创建设备的IRF端口2，与物理端口Ten-GigabitEthernet1/0/25绑定，并保存配置。

H3C-S7506E实现IRF虚拟化功能

H3C 5500 -EI SI IRF 配置
1.5.1 配置IRF域编号1. IRF域简介域是一个逻辑概念，设备通过IRF链路连接在一起就组成一个IRF，这些成员设备的集合就是一个IRF域。
为了适应各种组网应用，同一个网络里可以部署多个IRF，IRF之间使用域编号（DomainID）来以示区别。
如图1-7所示，Switch A和Switch B组成IRF1，Switch C和Switch D组成IRF2。
如果IRF1和IRF2之间有LACP MAD检测链路，则IRF1和IRF2会通过检测链路互相发送MAD检测报文，从而彼此影响IRF系统的状态和运行。
这种情况下，可以给两个IRF配置不同的域编号，以保证两个IRF互不干扰。
配置IRF域编号后，成员设备发出的扩展LACP报文中将携带IRF域信息，用以区分不同IRF的LACP检测报文，避免与其它IRF产生混淆。
图1-7 多IRF域示意图2. 配置IRF域编号表1-2 配置IRF域编号●IRF域编号的配臵必须在开启LACP MAD检测功能之前进行。
●建议用户为同一IRF中的成员设备配臵统一的IRF域编号，否则会影响LACP MAD检测功能的正常运行。
●在完成上述配臵后，在任意视图下执行display irf命令可以显示IRF域编号的配臵情况，通过查看显示信息验证配臵的效果。
1.5.2 配置成员编号IRF通过成员编号唯一的识别各成员设备，设备上的许多信息、配置与成员编号相关，比如接口（包括物理接口和逻辑接口）的编号以及接口下的配置、成员优先级的配置等。
●修改成员编号后，如果没有重启本设备，则原编号继续生效，各物理资源仍然使用原编号来标识；配置文件中，只有IRF端口的编号以及IRF端口下的配置、成员优先级的配置会跟着改变，其它配置均不会跟着改变。
●修改成员编号后，如果保存当前配置，重启本设备，则新的成员编号生效，需要用新编号来标识物理资源；配置文件中，只有IRF端口的编号以及IRF端口下的配置、成员优先级会继续生效，其它与成员编号相关的配置（比如普通物理接口的配置等）不再生效，需要重新配置。
