Cisco交换机配置入门2--帮助与注意事项

Cisco 交换机配置入门

机型：Cisco 3750

现在我们来继续讲解关于输入Cisco 命令时注意的一些事项与帮助

1.关于帮助

直接使用“?”，可以获得相应模式下的所支持的命令列表，如果再问号前面加上一些命令的开头的字母，就可以获得一些以此字母开头的命令，如：

AITG_FrontekCoreSW#s?
*s=show  sendsession  set  setup
show systat
输入"S?"，就可以获得以S开头的所有字母。

2、命令帮助

如果对某个命令的用法不熟悉时，也可以使用“?”来获取其详细的帮助，如想对show的命令作一个具体的了解，可以使用：“show ?”
