用户,特权,全局模式.docx

用户,特权,全局模式 了解用户模式、特权模式和全局模式 首先我们启动路由器这是我们发现命令行变为： R1> /用户模式的标志 现在我们来看一看在用户模式下我们可以进行哪些操作： R1>? Exec commands: access-enable Create a temporary Access-List entry access-profile Apply user-profile to interface call Voice call clear Reset functions connect Open a terminal connection crypto Encryption related commands. disable Turn off privileged commands disconnect Disconnect an existing network connection enable Turn on privileged commands /模式 exit Exit from the EXEC /式下退出 help Description of the interactive help system lat Open a lat connection lock Lock the terminal login Log in as a particular user logout Exit from the EXEC modemui Start a modem-like user interface mrinfo Request neighbor and version information from a multicast router 开启特权从用户模 mstat Show statistics after multiple multicast traceroutes mtrace Trace reverse multicast path from destination to source name-connection Name an existing network connection pad Open a X.29 PAD connection ping Send echo messages /向其他路由器发送信息包 ppp Start IETF Point-to-Point Protocol (PPP) release Release a resource renew Renew a resource resume Resume an active network connection rlogin Open an rlogin connection set Set system parameter (not config) show Show running system information / slip Start Serial-line IP (SLIP) ssh Open a secure shell client connection systat Display information about terminal lines tclquit Quit Tool Command Language shell telnet Open a telnet connection / terminal Set terminal line parameters traceroute Trace route to destination tunnel Open a tunnel connection udptn Open an udptn connection where List active connections x28 Become an X.28 PAD x3 Set X.3 parameters on PAD 查看命令 远程登录访问 接下来我们再进入特权模式下看一看可以进行哪些操作与用户模式下有什么区别： R1>enable R1#?
