CISCO路由器配置命令詳解設(shè)置試題

  思科認(rèn)證的考試內(nèi)容包括筆試和實(shí)驗(yàn)。筆試在全球認(rèn)證的考試中心進(jìn)行,時(shí)間為兩個(gè)小時(shí)。下面是小編收集的CISCO路由器配置命令詳解設(shè)置試題,希望大家認(rèn)真閱讀!

CISCO路由器配置命令詳解設(shè)置試題

  設(shè)置如下:

  Router1:

  interface Serial0

  ip address 192.200.10.1 255.255.255.0

  clockrate 1000000

  Router2:

  interface Serial0

  ip address 192.200.10.2 255.255.255.0

  !

  3. 舉例使用E1線路實(shí)現(xiàn)多個(gè)64K專線連接.

  相關(guān)命令:

  任務(wù) 命令

  進(jìn)入controller配置模式 controller {t1 | e1} number

  選擇幀類型 framing {crc4 | no-crc4}

  選擇line-code類型 linecode {ami | b8zs | hdb3}

  建立邏輯通道組與時(shí)隙的映射 channel-group number timeslots range1

  顯示controllers接口狀態(tài) show controllers e1 [slot/port]2

  注: 1. 當(dāng)鏈路為T(mén)1時(shí),channel-group編號(hào)為0-23, Timeslot范圍1-24; 當(dāng)鏈路為E1時(shí), channel-group編號(hào)為0-30, Timeslot范圍1-31.

  2.使用show controllers e1觀察controller狀態(tài),以下為幀類型為crc4時(shí)controllers正常的狀態(tài).

  Router# show controllers e1

  e1 0/0 is up.

  Applique type is Channelized E1 - unbalanced

  Framing is CRC4, Line Code is HDB3 No alarms detected.

  Data in current interval (725 seconds elapsed):

  0 Line Code Violations, 0 Path Code Violations

  0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

  0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

  Total Data (last 24 hours) 0 Line Code Violations, 0 Path Code Violations,

  0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins,

  0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

  以下例子為E1連接3條64K專線, 幀類型為NO-CRC4,非平衡鏈路,路由器具體設(shè)置如下:

  shanxi#wri t

  Building configuration...

  Current configuration:

  !

  version 11.2

  no service udp-small-servers

  no service tcp-small-servers

  !

  hostname shanxi

  !

  enable secret 5 $1$XN08$Ttr8nfLoP9.2RgZhcBzkk/

  enable password shanxi

  !

  !

  ip subnet-zero

  !

  controller E1 0

  framing NO-CRC4

  channel-group 0 timeslots 1

  channel-group 1 timeslots 2

  channel-group 2 timeslots 3

  !

  interface Ethernet0

  ip address 133.118.40.1 255.255.0.0

  media-type 10BaseT

  !

  interface Ethernet1

  no ip address

  shutdown

  !

  interface Serial0:0

  ip address 202.119.96.1 255.255.255.252

  no ip mroute-cache

  !

  interface Serial0:1

  ip address 202.119.96.5 255.255.255.252

  no ip mroute-cache

  !

  interface Serial0:2

  ip address 202.119.96.9 255.255.255.252

  no ip mroute-cache

  !

  no ip classless

  ip route 133.210.40.0 255.255.255.0 Serial0:0

  ip route 133.210.41.0 255.255.255.0 Serial0:1

  ip route 133.210.42.0 255.255.255.0 Serial0:2

  !

  line con 0

  line aux 0

  line vty 0 4

  password shanxi

  login

  Cisco路由配置基礎(chǔ)知識(shí)

  一、所處狀態(tài)各類

  router>

  用戶處于用戶命令狀態(tài),可以查看網(wǎng)絡(luò)和主機(jī)

  router#

  用戶處于特權(quán)模式,可以查看狀態(tài),還可以看到和更改路由器的設(shè)置內(nèi)容

  router(config)#

  全局配置狀態(tài),可以設(shè)置路由的全局參數(shù)

  router(config-if)#;router(config-line)#;router(config-router)#.....

  處于局部配置狀態(tài),可以設(shè)置路由的局部參數(shù)

  二、配置端口ip

  命令

  en

  configt//全局模式

  interfacef0/0

  ipaddress192.168.1.1255.255.255.0//設(shè)置端口ip

  noshu//生效

  exit

  interfacef0/1

  ipaddress192.168.10.1255.255.255.0

  noshu

  exit

  end

  disable

  三、配置靜態(tài)路由

  命令

  en

  configt//全局模式

  iproute192.168.100.0255.255.255.0192.168.10.2//到192.168.100.0/24通過(guò)192.168.10.2接口

  end

  showiproute//可以看到前面標(biāo)明S,即為靜態(tài)路由

  四、配置動(dòng)態(tài)路由(RIP)

  命令

  en

  configt//全局模式

  norouterip//禁止rip協(xié)議

  routerip

  work192.168.1.0//work參數(shù)為路由的兩個(gè)端口對(duì)應(yīng)的網(wǎng)絡(luò)地址

  work192.168.10.0

  exit

  end

  disable

  五、配置DHCP

  命令

  en

  configt//全局模式

  ipdhcpexcluded-address192.168.1.1//需要排除的ip地址

  ipdhcppoolgr-dhcp-pool//ip地址池名

  default-server192.168.1.1//指定dhcp服務(wù)器

  work192.168.1.0255.255.255.0//配置網(wǎng)絡(luò)

  dns-server61.177.7.1//配置dns服務(wù)器

  exit

  end

  disable

  可以通過(guò)iphelper-address指定DHCP中繼代理

  interfaceFastEther0/1

  ipaddress192.168.1.1255.255.255.0

  iphelper-address192.168.10.2配置DHCP中繼代理,DHCP

  六、配置NAT

  命令

  en

  configt//全局模式

  interfacef0/0

  ipaddress192.168.1.1255.255.255.0

  ipnatinside//內(nèi)部端口

  noshu

  exit

  interfacef0/1

  ipaddress192.168.10.1255.255.255.0

  ipnatoutside//外部端口

  noshu

  exit

  access-list1permitany//設(shè)置一個(gè)可訪問(wèn)列表

  ipnatpoolgr-nat-pool192.168.10.3192.168.10.254mask255.255.255.0//設(shè)置分配池

  ipnatinsideresourcelist1poolgr-nat-pooloverload

  showipnattraslations

  clearipnattraslation*

  七、其它

  shrunning-config//顯示當(dāng)前運(yùn)行配置

  shstartup-config//顯示開(kāi)機(jī)配置

  shiproute//顯示路由

  shnattraslations//顯示nat當(dāng)前情況
