第一步：首先创建ftp服务器，windows或者linux都无所谓，只要能访问就好了。
第二步：使用cisco的计划任务功能来实现自动备份的目的；要想定时备份，首先要确保网络设备可以上网同步时间，当然如果时间设置的本来就没有问题，可以略去这一步，我在这里使用的是自动同步time.windows.com这个时间服务器具体配置如下：
echo sh.SendKeys “telnet x.x.x.x(你的网络设备)" >>telnet_tmp.vbs
echo WScript.Sleep 300 >>telnet_tmp.vbs
echo sh.SendKeys “{ENTER}” >>telnet_tmp.vbs
echo WScript.Sleep 3000 >>telnet_tmp.vbs
echo sh.SendKeys “用户名{ENTER}”>>telnet_tmp.vbs
echo WScript.Sleep 3000 >>telnet_tmp.vbs
echo sh.SendKeys “密码{ENTER}”>>telnet_tmp.vbs
echo WScript.Sleep 3000 >>telnet_tmp.vbs
echo sh.SendKeys “conf t {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “ip domain-lookup {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “ip name-server dns服务器地址 {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “clock timezone BeiJing 8 {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “ntp server time.windows.com {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “exit {ENTER}” >>telnet_tmp.vbs
start cmd.exe
cscript //nologo telnet_tmp.vbs
echo del telnet_tmp.vbs

讲上面这段代码另存为bat文件，执行后就会自动登录到设备上进行设置，同步时间。

第三步：时间同步完了，我们就要定期对设备进行备份了，具体为如下代码：

echo sh.SendKeys “telnet x.x.x.x网络设备地址” >>telnet_tmp.vbs
echo WScript.Sleep 300 >>telnet_tmp.vbs
echo sh.SendKeys “{ENTER}” >>telnet_tmp.vbs
echo WScript.Sleep 3000 >>telnet_tmp.vbs
echo sh.SendKeys “用户名{ENTER}”>>telnet_tmp.vbs
echo WScript.Sleep 3000 >>telnet_tmp.vbs
echo sh.SendKeys “密码{ENTER}”>>telnet_tmp.vbs
echo WScript.Sleep 3000 >>telnet_tmp.vbs
echo sh.SendKeys “conf t {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “kron policy-list backup-fri{ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “cli write{ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “cli copy running-config ftp://x.x.x.x {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “exit {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “kron occurrence backup at 22:00 Fri recurring{ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “policy-list backup-fri{ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “exit {ENTER}” >>telnet_tmp.vbs
echo sh.SendKeys “exit {ENTER}” >>telnet_tmp.vbs
start cmd.exe
cscript //nologo telnet_tmp.vbs
echo del telnet_tmp.vbs
其实就是用到了
kron policy-list backup-fri
cli write
cli copy running-config ftp://x.x.x.x
kron occurrence backup at 22:00 Fri recurring
policy-list backup-fri
首先是创建一个计划任务叫backup-fri,然后在计划任务中,首先备份配置，然后把配置上传到ftp上去，然后创建计划时间，例如在每周五的22：00去执行一次。
好了，有了上面这些就可以自己写脚本去自动定时备份网络设备了。
