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。

二层以太网链路聚合IRF典型配置举例（H3C）

二层以太网链路聚合IRF典型配置举例（H3C）网工圈网络工程师阿龙圈内最早的公益公众号,本号已认证！学网络关注我一个就够了！（关注近5w ）关注听说99%的网工都来这里充电吖1 简介本文档介绍以太网链路聚合特性的配置举例。

2 配置前提本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。

如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。

本文档假设您已了解以太网链路聚合特性。

3 二层以太网链路聚合配合IRF典型配置举例3.1 组网需求如图2所示，接入层和汇聚层都有两台设备，现要求使用链路聚合特性和IRF特性实现以下需求：由于公司人员不断增加，要求接入层具有易管理能力和强扩展能力，可以提供更多的端口来满足PC的接入需求。

由于接入层的流量增加，要求增强接入层到汇聚层的链路具有较高可靠性，且可实现流量的负载分担。

图2 以太网链路聚合配置IRF配置组网图3.2 配置思路要使接入层具有易管理能力和强扩展能力，可通过配置IRF功能，轻松扩展接入层端口数量、带宽。

为了提高链路可靠性，可通过配置链路聚合配合IRF功能实现，每台接入层设备双上行连到汇聚层上，并且将四条上行链路进行聚合，当某个成员设备离开IRF，其它成员设备上的链路仍能收发报文，从而提高了链路的可靠性。

可以在汇聚层IRF和接入层IRF上同时开启LACP MAD功能，使两个IRF相互作为中间设备，完成各自的LACP MAD检测。

以快速排查IRF分裂原因并及时恢复成员设备IRF状态。

3.3 配置注意事项IRF物理端口必须工作在二层模式下，才能与IRF端口进行绑定。

与同一个IRF端口绑定的多个IRF物理端口必须工作在相同模式。

IRF中成员设备间相连的IRF物理端口必须配置为同一种工作模式配置聚合组的成员端口过程中，建议配置顺序：在端口视图下使用display this命令查看端口上是否存在属性类配置（包括端口隔离配置、QinQ配置、VLAN配置、VLAN映射），如果有这类配置，请使用对应的undo命令删除这些配置，使端口保持在缺省属性类配置状态，然后再把端口加入到新创建的聚合组内。

H3C交换机IRF配置指导

设备默认member为1，所以第一台不需要改member号，以上都不是建立IRF的关键配置，这些都可以等IRF建立之后再统一配置，关键是配置IRF端口。
interface Ten-GigabitEthernet1/0/29
shut
#
interface Ten-GigabitEthernet1/0/30
shut
#
irf-port2/2
port group interface Ten-GigabitEthernet2/0/29
port group interface Ten-GigabitEthernet2/0/30
此处必须写为2/2，因为该端口为接受第一台IRF信息，又因为remember改成了2，如果还有第三台的话，则还可以新增irf-port2/1
undo shut
#
interface Ten-GigabitEthernet1/0/30
undo shut
#
Save
#
Irf-port-configuration active //激活irf端口配置
在配置第二台设备之前就可以按照预先规划的接口将两台设备互联起来，等两台IRF端口配置都激活后备机会自动重启，所以保存配置也很关键。
#
interface Ten-GigabitEthernet2/0/29
undo shut
#
interface Ten-GigabitEthernet2/0/30
undo shut
#
Save
必须保存配置，否则下一条命令一配就会重启，配置全部丢失，irfctive

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。

(4)配置LACP MAD检测# 创建一个动态聚合端口，并使能LACP MAD检测功能。

<DeviceA> system-view[DeviceA] interface bridge-aggregation 2[DeviceA-Bridge-Aggregation2] link-aggregation mode dynamic[DeviceA-Bridge-Aggregation2] mad enable[DeviceA-Bridge-Aggregation2] quit# 在聚合接口中添加成员端口GigabitEthernet1/0/1和GigabitEthernet2/0/1，专用于两台IRF 成员设备与中间设备进行LACP MAD检测。

从节约成本的角度考虑，使用一台支持LACP功能的交换机即可。

# 创建一个动态聚合端口。

2. 组网图图1-14 IRF典型配置组网图（BFD MAD检测方式）配置思路3.处于局域网的汇聚层，为了将汇聚层的转发能力提高一倍，需要另外增Device A?加一台设备Device B。

配置IRF，需IRF链路故障导致IRF分裂、网络中存在两个配置冲突的为了防止万一IRF?检测方式MAD要启用检测功能。

因为成员设备比较少，我们采用BFD MAD 来监测IRF的状态。

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。

(1)配置设备编号# Device A保留缺省编号为1，不需要进行配置。

# 在Device B上将设备的成员编号修改为2。
