  思科认证的考试内容包括笔试和实验。笔试在全球认证的考试中心进行,时间为两个小时。下面是小编收集的CISCO路由器配置命令详解设置试题,希望大家认真阅读!

  设置如下:

  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. 举例使用E1线路实现多个64K专线连接.

  相关命令:

  任务 命令

  进入controller配置模式 controller {t1 | e1} number

  选择帧类型 framing {crc4 | no-crc4}

  选择line-code类型 linecode {ami | b8zs | hdb3}

  建立逻辑通道组与时隙的映射 channel-group number timeslots range1

  显示controllers接口状态 show controllers e1 [slot/port]2

  注: 1. 当链路为T1时,channel-group编号为0-23, Timeslot范围1-24; 当链路为E1时, channel-group编号为0-30, Timeslot范围1-31.

  2.使用show controllers e1观察controller状态,以下为帧类型为crc4时controllers正常的状态.

  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

  以下例子为E1连接3条64K专线, 帧类型为NO-CRC4,非平衡链路,路由器具体设置如下:

  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

  !

  ip route 133.210.42.0 255.255.255.0 Serial0:2

  !

  line con 0
