SecureCRT脚本

2021-06-22 | No comments

SecureCRT本身提供一种录制脚本的功能，可以通过录制脚本得到一个示例， 然后在此基础进行更改， 得到自己想要的脚本。

示例

#$language = "VBScript"
#$interface = "1.0"

crt.Screen.Synchronous = True

' This automatically generated script may need to be
' edited in order to work correctly.

Sub Main
	While 1     <<<<< 循环
		crt.Screen.Send "telnet  10.1.1.1" & chr(13)
		crt.Screen.WaitForString "Username: "
		crt.Screen.Send "cisco" & chr(10) & "cisco" & chr(10) & "show tcp trace " & chr(124) & " in vrfid " & chr(124) & " ex 0x60000000" & chr(13) & "exit" & chr(13)
		crt.Screen.WaitForString "[ciscotac@CNP " & chr(126) & "]$ "
		crt.Screen.Send chr(13)
		crt.Sleep 5000    <<<<< sleep 5s
	WEnd
End Sub

Others

就目前来说， 循环+send chr + wait chr 已经满足我的一些测试，后续再遇到其他的发现再添加。

#### for 循环
    For i = 1 To 10 
    Next

NCS55 SPAN to File(New Feature)

2021-06-06 | No comments

一直以来SPAN都是作为排查丢包问题很好用的feature， 但是在XR低版本上存在很多的限制，比如只支持local SPAN， 只能要求现场有人协助连个PC，将流量SPAN到PC上进行抓包，现在从XR 7.1.2 版本开始我们支持将SPAN的流量保存成一个文件，可以直接远程从设备上copy 出来。
