Cisco交换机配置入门2--帮助与注意事项

    Cisco 交换机配置入门 网管有家www.bitscn.net

    机型：Cisco 3750 网管网www_bitscn_com

    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： 网管联盟bitsCN_com

    AITG_FrontekCoreSW#s? 网管网www_bitscn_com

    *s=show  send    session  set  setup 中国网管论坛bbs.bitsCN.com

    show     systat
   
   
    输入\"S?\"，就可以获得以S开头的所有字母。 网管u家www.bitscn.net

    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 ?”

    以上是帮助选项，我们再来看看其他的快捷方式：

网管u家u.bitsCN.com

    1、使用TAB键
　　
    当输入命令的一部分字母时，按下TAB键，系统就可以自动输入此命令的剩余字母，如： 网管u家u.bitscn@com

    AITG_FrontekCoreSW#sh　　－－－TAB键
    AITG_FrontekCoreSW#show
    AITG_FrontekCoreSW#show int　　－－－TAB键
    AITG_FrontekCoreSW#show interfaces 网管朋友网www_bitscn_net

    2、命令缩写
　　
    有些命令没有必要将所有的字母输入完全，输入一部分就可以了，如：

网管u家bitscn.net

    AITG_FrontekCoreSW#sh int　　　＝show interface
    Vlan1 is up, line protocol is up
    Hardware is EtherSVI, address is 0019.aa89.dd40 (bia 0019.aa89.dd40)
    ......... 网管有家bitscn.net

　　建议大家最好将命令记全。 中国网管联盟bitsCN.com
