用户,特权,全局模式.doc

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 /开启特权模式 exit Exit from the EXEC /从用户模式下退出 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 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 /查看命令 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 /远程登录访问 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：R1enableR1#?Exec commands: access-enable Create a temporary Access-List entry access-profile Apply user-profile to interface access-template Create a temporary Access-List entry alps ALPS exec commands archive manage archive files audio-prompt load ivr prompt auto Exec level Automation bfe For manual emergency modes setting call Voice call ccm-manager Call Manager Application exec commands cd Change current directory clear Reset functions clock Manage the system clock cns CNS agents configure Enter configuration mode connect Open a terminal connection copy Copy from one file to another crypto Encryption related commands. ct-isdn Run an ISDN component test command debug Debugging functions (see also undebug) delete Delete a file dir List files on a filesystem disable Turn off privileged commands disconnect Disconnect an existing network connection dot1x Dot1x Exec Commands enable Turn on privileged commands eou EAPoUDP erase Erase a filesystem event Event related commands exit Exit from the EXEC help Description of the interactive help system isdn Run an ISDN EXEC command on an ISDN interface lat Open a lat connection lock Lock the terminal login Log in as a particular user logout Exit from the EXEC microcode microcode commands modemui Start a modem-like user interface monitor Monitoring different system events more Display the contents of a file mpoa MPOA exec commands mrinfo Request neighbor and version information from a multicast router mrm IP Multicast Routing Monitor Test mstat Show statistics after multiple multicast traceroutes mtrace Trace reverse multicast path from destination to source name-connection Name an existing network connection ncia Start/Stop NCIA Server no Disable debugging functions pad Open a X.29 PAD connection ping Send echo messages ppp Start IETF Point-to-Point Protocol (PPP) pwd Display current working directory release Release a resource reload Halt and perform a cold restart rename Rename a file renew Renew a resource restart Restart Connection resume Resume an active network connection rlogin Open an rlogin connection rsh Execute a remote command sdlc Send SDLC test frames send Send a message to other tty lines set Set system parameter (not config) setup Run the SETUP command facility show Show running system information slip Start Serial-line IP (SLIP) squeeze Squeeze a filesystem ssh Open a secure shell client connection start-chat Start a chat-script on a line systat Display information about terminal lines tbct configure TBCT related parameters tclquit Quit Tool Command Language shell tclsh Tool Command Language shell telnet Open a telnet connection terminal Set terminal line parameters test Test subsystems, memory, and interfaces traceroute Trace route to destination tunnel Open a tunnel connection udptn Open an udptn connection undebug Disable debugging functions (see also debug) upgrade Upgrade software verify Verify a file vlan Configure VLAN parameters 进入vlan voice Voice Commands where List active connections write Write running configuration to memory, network, or terminal /保存信息 x28 Become an X.28 PAD x3 Set X.3 parameters on PAD这时我们发现在特权模式下的可以进行的操作明显多于用户模式下并且用户模式下可以进行的操作在特权模式下都可以运行，我们再来看一看全局模式下的命令又有什么变化R1#conf /当输入命令唯一时可以按Tab键来补全R1#configure tR1#configure terminal Enter configuration commands, one per line.
