利用SecureCRT实现网络设备自动备份-华为、H3C篇
（1）新建文本文件（注意保存路径，本次测试路径为D:\backup\list.txt）：x.x.x.x username password enable_password （#注：如果没有enable密码可以不写；每项用空格分割）
（2）新建文本文件H3C.txt（路径D:\backup\H3C.txt），内容如下：
# $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:\backup\list.txt",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)
crt.session.LogFileName = "D:\backup\h3c\201611\" & params(0) & ".txt"
crt.session.Log(true)
'Telnet到这个设备上
crt.Session.Connect "/TELNET " & params(0)
crt.Screen.WaitForString "Username:"
crt.Screen.Send params(1) & Chr(13)
'输入telnet密码
crt.Screen.WaitForString "Password:"
crt.Screen.Send params(2) & Chr(13)
'进特权模式
crt.Screen.Send "sup" & Chr(13)
crt.Screen.WaitForString "Password:"
crt.Screen.Send params(3) & Chr(13)
crt.Screen.waitForString ">"
'备份目前runing-config配置
str1 = "disp cur "
crt.Screen.Send str1 & Chr(13)
crt.Screen.WaitForString " ---- More ----"
crt.Screen.Send " "
'crt.Screen.Send Chr(13) " & vbcr
'备份完成后退出
crt.Screen.waitForString"return"
crt.Screen.waitForString ">"
'执行disp int br命令
crt.Screen.Send "disp int brief" & Chr(13)
crt.Screen.WaitForString " ---- More ----"
crt.Screen.Send " "
crt.Screen.waitForString ">"
crt.screen.send Chr(13)
crt.Session.Disconnect
loop
crt.Screen.Synchronous = False
End Sub
（3）修改上面文本后缀个是为.vbs，即H3C.vbs；
（4）运行CRT软件，菜单栏-->脚本-->执行-->找到脚本路径D:\backup\H3C.vbs；
（5）查看备份文件保存路径
