思科認證的`考試內容包括筆試和實驗。筆試在全球認證的考試中心進行,時間爲兩個小時。下面是小編收集的CISCO路由器配置命令詳解設置試題,希望大家認真閱讀!
設置如下:
Router1:
interface Serial0
ip address
clockrate 1000000
Router2:
interface Serial0
ip address
!
3. 舉例使用E1線路實現多個64K專線連接.
相關命令:
任務 命令
進入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隙的映射 channel-group number Timeslots range1
顯示controllers接口狀態 show controllers e1 [slot/port]2
注: 1. 當鏈路爲T1時,channel-group編號爲0-23, Timeslot範圍1-24; 當鏈路爲E1時, channel-group編號爲0-30, Timeslot範圍1-31.
2.使用show controllers e1觀察controller狀態,以下爲幀類型爲crc4時controllers正常的狀態.
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
以下例子爲E1連接3條64K專線, 幀類型爲NO-CRC4,非平衡鏈路,路由器具體設置如下:
