思科基礎知識：Cisco IOS簡介（4）
作者：佚名
Cisco的網際操作系統（IOS）是一個為網際互連優化的復雜的操作系統。是一個與硬件分離的軟件體系結構，隨網絡技術的不斷發展，可動態地升級以適應不斷變化的技術（硬件和軟件）。
Cisco IOS—編輯和幫助功能
可以使用Cisco高級的編輯功能來幫助配置路由器。在任意提示符下鍵入一個問號。（？），都將會得到在當前提示符下所有命令的清單。
下面是查找以某個字母開頭的快捷方式命令：
- Router(config)#i?
- interface ip ipx isis
在一個命令串中找下一個命令，可以先鍵入前面的命令然后輸入一個問號：
- 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
- Router(config)#interface serial 0 ?
- <cr>
- Router(config-if)#
