交换机升级问题？有两个包，升级选择哪一个？

交换机作为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命令保存交换机当前配置信息：

<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命令查看交换机当前的文件系统，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-         -  Jun 28 2011 14:41:16   logfile

   1     drw-         -  Jun 28 2011 14:42:56   diagfile

   2     -rw-     16256  Jun 28 2011 14:43:40   a.tar

   3     -rw-      1694  Jun 28 2011 14:47:12   startup.cfg

   4     -rw-      3432  Jun 28 2011 14:47:10   diag.tar.gz

   5     -rw-  23861744  Jun 28 2011 14:37:46   main.bin

<Sysname>

(3)      在命令行配置界面的用户视图下，执行tftp put命令将启动文件main.bin备份到TFTP文件服务器上：

<Sysname> tftp 192.168.1.1 put main.bin

Press CTRL+C to abort.

(4)      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 192.168.1.1 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S7000EA.ipe导入到交换机的Flash卡中：

<Sysname> tftp 192.168.1.1 get S7000EA.ipe

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

                                 Dload  Upload   Total   Spent    Left  Speed

<Sysname>

(2)      在命令行配置界面的用户视图下，执行boot-loader命令设置交换机下次启动使用的启动文件为S7000EA.ipe，并指定启动文件类型为main：

<Sysname> boot-loader file flash:/S7000EA.ipe slot 6 main

 Verifying the file flash:/S7000EA.ipe on slot 6..................................

...............................Done.

7506E images in IPE:

  S7000EA-CMW710-BOOT-test.bin

  S7000EA-CMW710-SYSTEM-test.bin

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

Add images to slot 6.

Decompressing file S7000EA-CMW710-BOOT-test.bin to flash:/S7000EA-CMW710-BOOT-test.bin..........................................Done.

Decompressing file S7000EA-CMW710-SYSTEM-test.bin to flash:/S7000EA-CMW710-SYSTEM

-test.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:/S7000EA.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 6.

<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 6:

Current software images:

  flash:/S7000EA-CMW710-boot-test.bin

  flash:/S7000EA-CMW710-system-test.bin

Main startup software images:

  flash:/S7000EA-CMW710-boot-test.bin

  flash:/S7000EA-CMW710-system-test.bin

Backup startup software images:

  None

<Sysname>

如上显示信息中，下一次启动的程序文件已经设置为S7000EA-CMW710-boot-test.bin和S7000EA-CMW710-system-test.bin。

(4)      在命令行配置界面的用户视图下，执行reboot命令重启交换机：

<Sysname> reboot

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

Current configuration will be lost after the reboot, save current configuration? [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...

Configuration is saved to flash successfully.

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

Now rebooting, please wait...

<Sysname>

System is starting...

(5)      交换机重启后，通过display version命令查看交换机的启动文件版本信息是否与升级的启动文件一致。
