Cisco交换机配置入门2--帮助与注意事项

3、显示完整的命令
　
再一个部分命令的后面直接加上“?”就可以显示其输出结果，如例子：

AITG_FrontekCoreSW#show interface ?
Async  Async interface
BVIBridge-Group Virtual Interface
CTunnelCTunnel interface
Dialer Dialer interface
Filter Filter interface

|  Output modifiers
<cr>

以上是帮助选项，我们再来看看其他的快捷方式：

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：

AITG_FrontekCoreSW#sh－－－TAB键
AITG_FrontekCoreSW#show
AITG_FrontekCoreSW#show int－－－TAB键
AITG_FrontekCoreSW#show interfaces

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：

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)
.........

建议大家最好将命令记全。
