目 录
本文档主要介绍了如何通过自动配置和Python功能使设备自动组成IRF。
本文档不严格与具体软、硬件版本对应，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。
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。
本文档假设使用的设备均处于独立运行模式。
本文档假设您已了解IRF、Python和自动配置的特性。
只有相同型号的机框之间才能建立IRF。建议您在进行IRF零配置时的所有成员设备上均使用相同的单板配置方案，即选用的单板数量及型号、安装槽位号、以及对应 单板的工作模式设置等都保持一致。
如图1所示，某公司两台设备Device A和Device B放置在距离网络管理员较远的地方，所有设备的物理连接已经完成。为了简少网络配置的工作量，需要该公司的管理员通过设备的IRF零配置功能对两台设备进行一定的初始配置。现要求通过IRF零配置实现以下功能：
· Device A和Device B自动组成IRF。
· 网络管理员能够通过Telnet方式远程登录Device A和Device B组成的IRF设备。
· 登录Device A和Device B虚拟成的IRF设备时需要密码认证。
图1 IRF零配置组网图
· 为了保证IRF零配置的成功执行，需要在Device A和Device B上电启动之前按图1所示将网络环境搭建完成，将进行IRF零配置所需的文件准备好并存储在HTTP服务器上，同时要保证DHCP服务器上已经配置完成。Device A和Device B启动时会先从HTTP server下载Python脚本，然后根据Python脚本中的命令控制整个IRF零配置的流程。关于IRF零配置的所需文件的详细介绍，请参见4.4.2 准备HTTP Server上的配置文件。
· 当设备初次上电会自动进入自动配置的流程；当设备中不存在下次启动配置文件的时候，设备启动以后也可以进入到自动配置的流程。
· 为了使设备能成功组成IRF，必须保证Device A和Device B所使用的软件版本相同，所以Python脚本中添加了为Device A和Device B加载相同的启动软件版本的内容。
本举例是在S7500EX-CMW710-R7168版本上进行配置和验证的。
# 启动DHCP服务，创建名称为1的DHCP地址池，配置地址池动态分配IP地址的网段为192.168.1.0/24。
<DeviceC> system-view
[DeviceC] dhcp enable
[DeviceC] dhcp server ip-pool 1
[DeviceC-dhcp-pool-1] network 192.168.1.0 24
# 配置DHCP客户端远程启动文件为HTTP形式的URL。
[DeviceC-dhcp-pool-1] bootfile-name http://192.168.1.40/device.py
[DeviceC-dhcp-pool-1] quit
(1) 创建Python脚本device.py并保存到HTTP服务器上。Python脚本是设备进行IRF零配置操作的主要文件，需要用户自行准备并保存在HTTP服务器上。Python脚本需要完成的主要操作：
· 判断Flash是否存在足够的存储空间（请用户根据实际情况进行判断）；
· 从HTTP服务器下载配置文件；
· 从HTTP服务器下载启动软件包；
· 从HTTP服务器下载sn.txt文件；
· 配置设备下次启动时使用的启动软件包；
· 解析sn.txt文件并修改设备的IRF成员编号；
· 配置设备下次启动时使用的配置文件；
· 重新启动设备。

(2) 创建配置文件serial_number.cfg（serial_number 为进行IRF零配置设备框的序列号，例如下面所使用的配置文件名称）并在保存到HTTP服务器上。配置文件包含了所有设备建立IRF、通过Telnet方式远程登录、登录时密码认证的相关命令。文件内容如下：
· 210235A045B05B0004354.cfg：
#
telnet server enable
#
irf mac-address persistent timer
irf auto-update enable
undo irf link-delay
irf member 1 priority 1
#
irf-port 1/1
port group mdc 1 interface Ten-GigabitEthernet1/3/0/1
#
interface GigabitEthernet1/3/0/1
port link-mode bridge
#
interface M-GigabitEthernet1/0/0/0
ip address 192.168.0.63 255.255.255.0
#
line vty 0 63
user-role network-admin
set authentication password simple 123
#
· 210235A045B05B0004350.cfg：
#
telnet server enable
#
irf mac-address persistent timer
irf auto-update enable
undo irf link-delay
irf member 2 priority 1
#
irf-port 2/2
port group mdc 1 interface Ten-GigabitEthernet2/3/0/1
#
interface GigabitEthernet1/3/0/1
port link-mode bridge
#
interface M-GigabitEthernet1/0/0/0
ip address 192.168.0.63 255.255.255.0
#
line vty 0 63
user-role network-admin
set authentication password simple 123
#
(3) 创建sn.txt文件并保存在HTTP服务器上。每个设备的主控板都有序列号，sn.txt文件将序列号和成员编号做一对一的映射，以便Pythone脚本能够自动给设备配置指定的成员编号。设备通过运行Python脚本来解析sn.txt文件，然后修改设备的IRF成员编号，并根据自身的成员编号来完成相应的IRF配置。文件内容如下：
sn Irf group Irf number
210235A045B05B0004354 100 1
210235A045B05B0004350 100 2
sn.txt文件中的sn列为设备机框的序列号（serial number），可以通过粘贴在设备机框后面板上的标签查看其序列号，也可以通过在设备上执行display device manuinfo命令进行查看。sn.txt文件中的Irf group列是用来标记IRF组的数字，用户可以自行编辑，不会对设备的配置产生影响。sn.txt文件中的Irf number列为设备在IRF组中的成员编号。
(4) 将软件启动包S7500E-X.ipe保存在HTTP服务器上。软件启动包是设备启动、运行的必备软件，使用自动配置进行软件升级，使现有设备（包括主用主控板和备用主控板）的启动软件版本一致，以保证Device A和Device B能够成功建立IRF。
启动HTTP管理软件，开启HTTP服务（配置过程略）。
下面以Telnet方式登录Device A为例验证设备是否成功完成自动配置，Device B和Device A验证效果相同，不再赘述。
