AUT是一个脚本，可以实现自动化安装IOS-XR，支持Turboboot，不过看了下AUT的介绍，暂时感觉不出用了这个脚本后会省多少功夫

https://www.youtube.com/watch?v=2DgXPi0Ink4

这个脚本不能在windows下调用，MAC，linux和类Unix系统都可以用
因为脚本用到pexpect模块，这个模块是纯的python模块，依赖pty 模块，pty模块是任何Posix系统标准库的一部分
下面是使用前的一些基本步骤，有兴趣的童鞋可以试试这个脚本

1. 下载后执行,有报错

x-mac:accelerated upgrade frank$ ./accelerated_upgrade -h
-bash: ./accelerated_upgrade: /router/bin/python: bad interpreter: No such file or directory

2. 找到python的目录：

x-mac:accelerated upgrade frank$ which python
/usr/bin/python

并用vi进到accelerated_upgrade，修改正确的路径
#!/usr/bin/python

3. 再次执行，发现仍然报错，需要单独安装pexpect：

x-mac:accelerated upgrade frank$ python accelerated_upgrade -h
Traceback (most recent call last):
  File "accelerated_upgrade", line 34, in 
    import pexpect
ImportError: No module named expect

注：pexpect 模块是python的交互模块，可以实现自动化脚本，如telnet，ssh，ftp等。

4. 下载并安装，安装方法可以看文件中的install文件，写的很清楚

5. 回过头来试下AUT，发现已经ok了，下面仅是一部分显示

x-mac:accelerated upgrade frank$ ./accelerated_upgrade -h
Usage: accelerated_upgrade [options]

Options:
  -h, --help            show this help message and exit
  -l LOGIN, --login=LOGIN
                        User name to login to the device. e.g.: -l admin.
  -L LOGIN2, --login2=LOGIN2
                        User name to 2nd login to the device. e.g.: -L admin.
  -p PASSWORD, --passwd=PASSWORD
                        Login password for the device. e.g.: -p passwd'.
  -P PASSWORD2, --passwd2=PASSWORD2
                        2nd Login password for the device. e.g.: -P passwd'.
  -T 'NAME', --tunnel='NAME'
                        List of inetremediate serevers to reach the device.
                        e.g.: -T server-1,server-2

6. ok，找台设备试下脚本就可以了
