CISCO路由器配置命令详解设置试题
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
clockrate 1000000
Router2:
interface Serial0
ip address
!
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
