3、2.特權(quán)模式:可以使用更多查看性質(zhì)的命令和一些少量修改路由器參數(shù)的命令.3.全局配置模式:不能使用查看性質(zhì)的命令,但是確實做全局性修改和設(shè)置的模式,它還可以向下分為一些子模式,比如接口配置模式,線路配置模式,路由進程配置模式等等.配置實例一:Router>enableRouter#configure terminalEnter configuration commands, one per line.

16、用登陸命令,退出之后,路由器是不會提示輸入密碼的.控制臺線路密碼為控制臺線路所用;輔助接口(AUX)線路密碼為輔助接口線路所用;虛擬終端線路(VTY)是為telnet會話所用,路由器根據(jù)Cisco IOS軟件版本不同,支持多條VTY會話數(shù)目也不同.所有密碼是以明文方式保存在DRAM(running-config)文件里的.配置實例一:Aiko(config)#line console 0Aiko(config-line)#password AikoAiko(config-line)#loginAiko(config-line)#line aux 0Aiko(config-line)#passw

22、speed4.開啟接口:Aiko(config-if)#no shutdown解釋:默認所有接口都是處于關(guān)閉狀態(tài)的,對于一般的以太網(wǎng)接口,設(shè)置了IP地址信息之后,只需要開啟該接口即可;對于串行接口,還要注意在DCE端設(shè)置時鐘頻率,以便為DTE端提供時鐘頻率進行同步.當然這一般用于實驗室背對背環(huán)境中,真正現(xiàn)實環(huán)境中,DCE是由CSU/DSU來提供,無須用戶設(shè)置.另外要注意的是,端到端(end-to-end)的連接,直連的接口必須處于同一子網(wǎng).配置實例一:路由器Aiko配置如下:Aiko#configure terminalEnter configuration commands, one per
