V7命令行，修改了密码策略，密码长度为5，为什么密码设置为cisco不行

开启密码策略后除了长度一般还有复杂度要求的，比如要同时包含数字、字母等多种字符，你可以在设备上dis password-c查看当前具体的策略都有哪些要求，命令回显的解释可以看这个链接：

undo password-control enable
undo password-control length enable
undo password-control length
undo password-control aging
undo password-control aging enable
undo password-control composition
undo password-control composition enable
undo password-control alert-before-expire
undo password-control login idle-time
undo password-control login-attempt
undo password-control change-password first-login enable
undo password-control change-password weak-password enable
undo password-control expired-user-login
undo password-control complexity same-character check
undo password-control complexity user-name check
undo password-control update-interval
把所有的密码策略限制都取消了
