H3C路由器SR6608设备通过pc远程升级，pc和设备通过vpn实例进行连接，升级步骤以及查看设备下次启动项，以及升级全部步骤。 h3c账号登录无法查看，无法查看具体步骤，请提供一下具体步骤。

B.4 通过命令行进行软件升级

B.4.1 使用TFTP协议升级路由器的启动文件

路由器作为TFTP Client，访问TFTP文件服务器的制定路径，完成启动文件的备份及升级操作，具体操作步骤如下：

1. 备份当前启动文件和配置文件

(1)       在命令行配置界面的任意视图下，执行save命令保存路由器当前配置信息：

<Sysname> save

The current configuration will be written to the device. Are you sure? [Y/N]:y

Please input the file name(*.cfg)[flash:/startup.cfg]

(To leave the existing filename unchanged, press the enter key):

flash:/startup.cfg exists, overwrite? [Y/N]:y

Validating file. Please wait...

Saved the current configuration to mainboard device successfully.

<Sysname>

(2)       在命令行配置界面的用户视图下，执行dir命令查看路由器当前的文件系统，确认启动文件及配置文件名，以及Flash的剩余空间，保证Flash有足够空间放入新的启动文件：

<Sysname> dir

Directory of flash:

   0 drw-           - Aug 12 2013 16:38:21   diagfile

   1 -rw-         895 Aug 20  2013 09:33:00  ifindex.dat

   4 drw-           - Aug 12 2013 16:38:21   seclog

   5 -rw-     9427968 Aug 12 2013 16:34:56   sr6600x-cmw710-boot-r7103p01.bin

   6 -rw-   107847680 Aug 12 2013 16:35:23   sr6600x-cmw710-system-r7103p01.bin

   7 -rw-        3740 Aug 20 2013 09:33:01   startup.cfg

   8 -rw-      114861 Aug 20 2013 09:33:01   startup.mdb

(3)       在命令行配置界面的用户视图下，执行tftp put命令将配置文件startup.cfg备份到TFTP文件服务器上：

<Sysname> tftp 192.168.2.80 put startup.cfg

Press CTRL+C to abort.

2. 升级启动文件

(1)       在命令行配置界面的用户视图下，执行tftp get命令将启动文件SR6604X.ipe导入到路由器的Flash中：

<Sysname> tftp 192.168.2.80 get SR6604X.ipe

Press CTRL+C to abort.

<Sysname>

(2)       在命令行配置界面的用户视图下，执行boot-loader命令设置路由器下次启动使用的启动文件为SR6604X.ipe，并指定启动文件类型为main：

<Sysname> boot-loader file flash:/SR6604X.ipe slot 0 main

Verifying the IPE file and the images..............Done.

H3C SR6604X images in IPE:

  SR6600X-CMW710-BOOT-R7103P02.bin

  SR6600X-CMW710-SYSTEM-R7103P02.bin

This command will set the main startup software images. Continue? [Y/N]:y

Add images to slot 0.

Decompressing file SR6600X-CMW710-BOOT-R7103P02.bin to flash:/SR6600X-CMW710-BOO

T-R7103P02.bin.......Done.

Decompressing file SR6600X-CMW710-SYSTEM-R7103P02.bin to flash:/SR6600X-CMW710-S

YSTEM-R7103P02.bin..............................................................

........Done.

Decompression completed.

You are recommended to delete the .ipe file after you set startup software image

s for all slots.

Do you want to delete flash:/SR6604X.ipe now? [Y/N]:y

The images that have passed all examinations will be used as the main startup so

ftware images at the next reboot on slot 0.

<Sysname>

(3)       在命令行配置界面的用户视图下，执行display boot-loader命令查看设备的启动程序文件信息：

<Sysname> display boot-loader

Software images on slot 0:

Current software images:

  flash:/SR6600X-CMW710-BOOT-R7103P01.bin

  flash:/SR6600X-CMW710-SYSTEM-R7103P01.bin

Main startup software images:

  flash:/SR6600X-CMW710-BOOT-R7103P02.bin

  flash:/SR6600X-CMW710-SYSTEM-R7103P02.bin

Backup startup software images:

  None

如上显示信息中，下一次启动的程序文件已经设置为SR6604X.ipe解压后的对应的.bin文件。

(4)       在命令行配置界面的用户视图下，执行reboot命令重启路由器：

<Sysname> reboot

Start to check configuration with next startup configuration file, please wait..

.......DONE!

This command will reboot the device. Continue? [Y/N]:y

Now rebooting, please wait...

%Aug 20 10:44:06:159 2013 H3C DEV/5/SYSTEM_REBOOT: System is rebooting now.

System is starting...

(5)       路由器重启后，通过display version命令查看路由器的启动文件版本信息是否与升级的启动文件一致。
