s e c u r e C R T V B S脚本
语法
常用语句：
1.CRT命令?
‘发送命令?
crt.Screen.Send “whyy@dsl-vty” & chr(13)?
‘等待字符串出现?
crt.Screen.WaitForString “Password:”?
‘等待字符串出现，等待1秒钟?
crt.Screen.WaitForString (“Password:”,1)?
‘开启同步?
crt.Screen.Synchronous = True?
‘判断指针1秒内不移动，用于确定安全连接可以进行后续代码输入操作?
Do?
bCursorMoved = crt.Screen.WaitForCursor(1)?
Loop until bCursorMoved = False?
‘判定是否已经连接到设备?
if crt.Session.Connected = true then?
‘断开连接?
crt.session.disConnect?
‘激活窗口用于多tab页面?
crt.Activate?
‘连接到指定设备?
crt.session.Connect(“/telnet ” & b(n))?
‘延时1秒?
crt.Sleep 1000
2.vbScript语句
a.文件操作?
Set fso = CreateObject(“Scripting.FileSystemObject”) ‘创建文件对象?
Set file1 = fso.OpenTextFile(“c:\”,1, False) ‘设置文件对象 1 只读模式;2 写模式;8 在文件末尾进行写操作? objFso.FileExists(“文件路径”) ‘判定文件是否存在，存在返回trus，否则返回false?
file1.At EndOfStream <> True ‘如果文件末尾无数据返回true，否则返回false?
line = file1.ReadLine ‘读取第一行文本数据，并将读取位移动到下一行?
params = Split (line) ‘分割读取的行数据，用空格符分割?
file1.Close ‘关闭文件
b.系统文档操作?
‘创建shell对象，对系统特殊文档操作?
Set objShell = CreateObject(“WScript.Shell”)
‘返回”我的文档”的路径给变量szMyDocs，可以动态的返回”我的文档”的路径?
szMyDocs = objShell.SpecialFolders(“MyDocuments”)
‘设置文件路径到变量中?
szSessionsFile = szMyDocs & “\”
3.知识点?
（1）判断文件是否存在?
if Not objFso.FileExists(szSessionsFile) then ‘如果txt文件不存在，就报错并退出sub?
crt.Dialog.MessageBox “Session list file n ot found:” & vbcrlf &?vbcrlf & szSessionsFile & vbcrlf & vbcrlf &?“Create a session list file as de scrib ed in the description of ” & “this script code and then run the script again.”?
exit sub?
end if
（2）容错机制?
On Error Resume Next ‘后面代码错误会继续执行?
crt.Session.Connect “/telnet ” & vSessionsArray(0)?
szError = Err.Description ‘将错误表述信息放入变量szError中?
On Error Goto 0 ‘关闭容错机制
（3）判断是否安全连接?
‘判断是否连接正常?
if crt.Session.Connected then?
crt.Screen.Synchronous = True ‘同步显示?
‘第一次连接时的安全检测?
Do?
bCursorMoved = crt.Screen.WaitForCursor(1)?
Loop until bCursorMoved = False?
’ 一旦光标在一秒内停止移动，我们就认为他已经安全的连接上了远程设备?
end if
（4）安全关闭连接?
’ 断开连接?
crt.session.disconnect?
’ 等待连接关闭?
Do?
crt.Sleep 100?
Loop While crt.Session.Connected = True ‘每100毫秒判断连接是否断开
（5）说明:?
1.CRT默认tab的index为1?
2.要创建第二个标签页tab，必须使用函数set newtab = objCurrentTab1.Clone()复制标签页为新的tab页面? 否则报错tab 2 超出index范围rang
函数：?
Set objCurrentTab1 = crt.GetTab(1) ‘创建标签页1?
objCurrentTab1.session.disConnect ‘断开标签页1的当前连接?
objCurrentTab1.Activate ‘激活标签页1?
objCurrentTab1.session.Connect(“/telnet 172.16.205.1” ) ‘标签页1连接设备172.16.205.1?
set newtab = objCurrentTab1.Clone() ‘复制标签页1到新标签页
示例：?
【示例一】
$language = "VBScript"
$interface = "1.0"
'本脚本示范：自动登录到某台3550交换机设备，自动输入远程登录密码，同时自动进入特权模式
'自动输入特权密码，同时运行show version命令
Sub Main
crt.Screen.Synchronous = True
vbs脚本怎么停止'通过telnet连接到192.168.1.1
crt.Session.Connect "/TELNET 192.168.1.1"
crt.Screen.WaitForString "Password:"
crt.Screen.Send "cisco" & vbCr
crt.Screen.waitForString  ">"
crt.Screen.Send "enable" & vbcr
crt.Screen.WaitForString "Password:"
crt.Screen.Send "cisco" & vbcr
crt.Screen.waitForString "#"
crt.Screen.Send "show version" & vbcr
crt.Screen.waitForString "--More--"
crt.Screen.Send " "
crt.Screen.Synchronous = False
End Sub
【示例二】
$language = "VBScript"
$interface = "1.0"
'本脚本示范：从一个文件里面自动读取设备IP地址，密码等，自动将设备配置备份
Sub Main
'打开保存设备管理地址以及密码的文件
Const ForReading = 1, ForWriting = 2, ForAppending = 8
Dim fso,file1,line,str1,params
Set fso = CreateObject("Scripting.FileSystemObject")
Set file1 = fso.OpenTextFile("d:\",Forreading, False)
crt.Screen.Synchronous = True
DO While file1.AtEndOfStream <> True
'读出每行
line = file1.ReadLine
'分离每行的参数 IP地址密码 En密码
params = Split (line)
'Telnet到这个设备上
crt.Session.Connect "/TELNET " & params(0)
'输入telnet密码
crt.Screen.WaitForString "Password:"
crt.Screen.Send params(1) & vbcr
'进特权模式
crt.Screen.Send "enable" & vbcr
crt.Screen.WaitForString "Password:"
crt.Screen.Send params(2) & vbcr
crt.Screen.waitForString "#"
'备份目前Startup配置
str1 = "copy startup tftp://192.168.1.2/"
str1 = str1 & "backup(" & params(0) &")" & ".cfg"
crt.Screen.Send str1 & vbcr
crt.Screen.WaitForString "]
"
crt.Screen.Send vbcr
crt.Screen.WaitForString "]
"
crt.Screen.Send vbcr
'备份完成后退出
crt.Screen.waitForString "#",3
crt.Session.Disconnect
loop
crt.Screen.Synchronous = False
End Sub
<文本文件为事先编辑好的?
格式如：?
192.168.1.1 cisco cisco?
192.168.1.254 cisco cisco?
前面是IP地址，后面是telnet密码，最后是enable密码
Sub Main
'打开保存设备管理地址以及密码的文件
Const ForReading = 1, ForWriting = 2, ForAppending = 8
Dim fso,file1,line,str1,params
Set fso = CreateObject("Scripting.FileSystemObject")
Set file1 = fso.OpenTextFile("d:\",Forreading, False)            crt.Screen.Synchronous = True
DO While file1.AtEndOfStream <> True
'读出每行
line = file1.ReadLine
'分离每行的参数 IP地址密码 En密码
params = Split (line)
'Telnet到这个设备上
crt.Session.Connect "/TELNET " & params(0)
'输入telnet密码
crt.Screen.WaitForString "Password:"
crt.Screen.Send params(1) & vbcr
'进特权模式
