网络设备信息采集脚本

16 7 月, 2021,由 frank撰写

在常规测试中，经常需要在测前、测后抓取大量信息留存，不同厂商命令又不一样，黏贴复制采集工作量巨大，效率又低，所以需要写一个自动化脚本帮助自动化采集。自动化脚本有很多种方法编写，这里主要使用简单易用的Python，由于使用的是SecureCRT，所以直接选择了Python与SecureCRT的组合自动化脚本，其实之前写过一些，不过此篇用到了多个Session；

Python独立自动化脚本，可以参考之前的文章：
- Auto check share memory utilization for IOX by Python
Python 与SecureCRT组合的自动化脚本，可以参考之前的文章：
- CRT + Python for “crt.Screen.Send”
- SecureCRT + Python

SecureCRT最开始支持VB脚本，后来逐步转到Python。官网也有很多example可以供参考，如果感兴趣可以参考：

脚本功能

此自动化脚本可以复用，根据需求任意更改，简单上手；另外Juniper带“table”的命令会扰乱SecureCRT的脚本，更改后恢复正常，代码正文中的是最终版本，同时也去掉了等待时间；其实脚本还可以优化下，但为了简单点，就写了10多个函数；

指定路径并按照“日_时分”格式自动创建文件夹；
SecureCRT自动登录14台路由设备，并开启记录log功能；
采集14台设备信息，自动保存log，以“年-月-日-时-分”命名log文件；
采集后自动关闭Session；

show route yyyyyyyy extensive table C-CT |no-more\r

代码模块

Python部分

获取时间并赋予文件名及文件夹名称；
通过系统函数自动创建文件夹；
使用time函数等待特定时间；
while循环函数使用；

SecureCRT部分

通过objTab开启多个Session；
记录log功能；
发送命令函数；
等待结果函数；
关闭Tab会话；

下面是常用的一些Tab函数：

crt.Session.ConnectInTab()
crt.GetTabCount()
crt.GetTab()
objTab.Activate() 
objTab.Clone()
objTab.Close()
objTab.ConnectSftp()
objTab.Index()
objTab.Caption()
objTab.Session.Disconnect()
objTab.Session.Connected()
objTab.Screen.Send()

使用方法

打开SecureCRT -> 选择Script -> 选择Run -> 选择 “xxx.py” 脚本 -> 可以去干别的了~
