Cisco IOS—编辑和帮助功能
可以使用Cisco高级的编辑功能来帮助配置路由器。在任意提示符下键入一个问号。（？），都将会得到在当前提示符下所有命令的清单。
下面是查找以某个字母开头的快捷方式命令：
- Router(config)#i?
- interface ip ipx isis
在一个命令串中找下一个命令，可以先键入前面的命令然后输入一个问号：
- Router(config)#interface ?
- Async Async interface
- BVI Bridge-Group Virtual Interface
- CTunnel CTunnel interface
- Dialer Dialer interface
- Ethernet IEEE 802.3
- Group-Async Async Group interface
- Lex Lex interface
- Loopback Loopback interface
- Multilink Multilink-group interface
- Null Null interface
- Serial Serial
- Tunnel Tunnel interface
- Vif PGM Multicast Host interface
- Virtual-Template Virtual Template interface
- Virtual-TokenRing Virtual TokenRing
- range interface range command
- Router(config)#interface serial ?
- <0-1> Serial interface number
