1、vbs 脚本在 secureCRT 的应用（设备升级篇）最近在给中兴的 EPON 的 ONU 设备升级，有 113 台设备，没有连接 OLT，主管说让我安装设备之前最好先升级好，以免旧版本的 BUG 会引起客户的不满。于是我用 TFTP 方式按照 TXT 脚本复制给 ONU 升级，升级完后，我发现工作效率极低，因为 ONU 有响应时间，如果用脚本复制进去执行的话，会导致缺损命令，导致多行命令无法一次执行完，必须一条条粘上去，极度影响了工作效率，大概花了一个下午的时间只升级了 7 台设备，这样的工作效率我是无法忍受的。之前看到过 secureCRT 支持 vbs 脚本，但是由于我的编程学的非常差
2、，只能暂时靠 secureCRT 的录制脚本功能，暂时解决升级问题，但是过程中有很多问题，比如每台 ONU 的 mac 地址不同，所以完全按照录制脚本是不行的，必须自己修改。最后我完成了无数次的实验，解决了很多 bug，现在的 vbs 脚本，基本上能够满足我 TFTP 升级 ONU 的工作效率，大概用了四五天的时间，就把 113 台设备升级完毕了。过程只需要插入电源，开启 secureCRT 的连接，最后弹出对话框表示结束，整个升级工作完成，最后把 ONU 和两个 PON 的 mac 地址和编号对应，就行了。以下是 TFTP 升级代码（之前已经在 secureCRT 上设置了初始回车键进入升级
