  HDLC是CISCO路由器使用的缺省协议,一台新路由器在未指定封装协议时默认使用HDLC封装。

  1. 有关命令

  端口设置

  任务 命令

  设置HDLC封装 encapsulation hdlc

  设置DCE端线路速度 clockrate speed

  复位一个硬件接口 clear interface serial unit

  显示接口状态 show interfaces serial [unit] 1

  注:1.以下给出一个显示Cisco同步串口状态的例子.

  Router#show interface serial 0

  Serial 0 is up, line protocol is up

  Hardware is MCI Serial

  Internet address is 150.136.190.203, subnet mask is 255.255.255.0

  MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/255, load 1/255

  Encapsulation HDLC, loopback not set, keepalive set (10 sec)

  Last input 0:00:07, output 0:00:00, output hang never

  Output queue 0/40, 0 drops; input queue 0/75, 0 drops

  Five minute input rate 0 bits/sec, 0 packets/sec

  Five minute output rate 0 bits/sec, 0 packets/sec

  16263 packets input, 1347238 bytes, 0 no buffer

  Received 13983 broadcasts, 0 runts, 0 giants

  2 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 2 abort

  22146 packets output, 2383680 bytes, 0 underruns

  0 output errors, 0 collisions, 2 interface resets, 0 restarts

  1 carrier transitions

  2. 举例

  

  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
