irf设备版本升级（irf-port-configuration active）

//注：本次升级共有两台H3C 7506交换机做了IRF，每台交换机两块引擎板，总共4块引擎板上的IOS都要升级；

//注：本次升级业务已规避，可以一次性重启此两台H3c 7506交换机，不需要主备倒换。

//注：交换机的新版IOS到官网下载

1、将笔记本电脑与交换机的(直连)网络打通。

在要升级的交换机上新建一个未占用的网段并配置IP地址，启用一个未占用的端口连接笔记本；给笔记本配置相同网段IP地址，使电脑与交换机通过网线能直连通信(或是利用现有的网段也行）。

[S-7506-IRF-1]inter Vlan-interface 3777

[S-7506-IRF-1-Vlan-interface3777]ip add 2.2.2.2 255.255.255.0

interface GigabitEthernet1/4/0/16

port link-mode bridge

port access vlan 3777

//注：笔记本IP配置2.2.2.1 255.255.255.0

//注：确保笔记本与交换机直连已通。

//注：在交换机上测试是否可以ping通笔记本的IP地址。

[S-7506-IRF-1-GigabitEthernet1/4/0/16]ping 2.2.2.1

56 bytes from 2.2.2.1: icmp_seq=4 ttl=128 time=1.818 ms

2、查看交换机主引擎flash剩余空间是否足够（剩余空间要大于上传的ios大小）

<S-7506-IRF-1>dir

Directory of flash:

0 drw- - Sep 28 2017 23:46:31 diagfile

1 -rw- 11826 Jan 15 2021 00:27:32 ifindex.dat

10 drw- - Dec 07 2016 13:40:02 versionInfo

1048576 KB total (783312 KB free)

3、笔记本上用启FTP服务(可以使用3CDaemon软件，此软件运行即可，复制FTP用户名、默认无密码)，笔记本端为服务器端；在交换机上连上FTP。

//注：2.2.2.1为笔记本配置的地址

<S-7506-IRF-1>ftp 2.2.2.1

Press CTRL+C to abort.

Connected to 2.2.2.1 (2.2.2.1).

220 3Com 3CDaemon FTP Server Version 2.0

User (2.2.2.1:(none)): anonymous

331 User name ok, need password

230-Next time, please use your email address as password.

230 User logged in

ftp> binary

200 Type set to I.

4、先将交换机上的配置及文件拷贝下来。以下只拷了文件大小 >0 的文件。

//注：有哪些文件可以看上面“步骤2”用dir命令显示出来的结果

ftp> put startup.cfg

227 Entering passive mode (2,2,2,1,218,87)

5、再次确认下主引擎的剩余空间，确认上传空间是否足够。

<S-7506-IRF-1>dir chassis1#slot0#flash:/

Directory of flash:

0 drw- - Sep 28 2017 23:46:31 diagfile

1 -rw- 11826 Jan 15 2021 00:27:32 ifindex.dat

5 -rw- 32005120 Dec 07 2016 13:30:50 s7500e-cmw710-boot-r7184.bin

6 -rw- 231346176 Dec 07 2016 13:35:45 s7500e-cmw710-system-r7184.bin

10 drw- - Dec 07 2016 13:40:02 versionInfo

1048576 KB total (783312 KB free)

(以下4个引擎板卡都要看，确认剩余空间够不够）

<S-7506-IRF-1>dir chassis?

chassis1#slot0#flash:/ //这块是默认空间，即上面输入dir查看的空间。

chassis1#slot1#flash:/

chassis2#slot0#flash:/

chassis2#slot1#flash:/

6、将要升级的文件上传

//注：具体文件名以官网下载的名称为准

//以下以要升级的ios文件名为S7500E-CMW710-SYSTEM-R7596P05.bin和S7500E-CMW710-BOOT-R7596P05.bin为例

ftp> get S7500E-CMW710-SYSTEM-R7596P05.bin
