1、CISCO路由器廣域網(wǎng)協(xié)議設(shè)置HDLC
HDLC
HDLC是CISCO路由器使用的缺省協(xié)議，一臺(tái)新路由器在未指定封裝協(xié)議
時(shí)默認(rèn)使用 HDLC 封裝。
1. 有關(guān)命令
端口設(shè)置
任務(wù)
命令
設(shè)置HDLC封裝
encapsulation hdlc
設(shè)置DCE端線路速度
clockrate speed
復(fù)位一個(gè)硬件接口
clear interface serial unit
顯示接口狀態(tài)
show interfaces serial [unit] 1
注:1.以下給出一個(gè)顯示 Cisco 同步串口狀態(tài)的例子.

2、ial 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
3、: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

2. 舉例
設(shè)置如下：
Router1:
interface Serial0
ip address 192.200.10.1 255.255.255.0
clockrate 1000000
Router2:
interface Seria
5、l0
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-groupnumber timeslots
range1
顯示 controllers 接口狀
態(tài)
show con
6、trollers e1 [slot/port]2
注：1.當(dāng)鏈路為T1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
7、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
8、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N0-CRC4,非平衡鏈路，路由 器具體設(shè)置如下:
