CISCO路由器廣域網(wǎng)協(xié)議設(shè)置HDLC

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. 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. 舉例 設(shè)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. 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 controllers 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 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: shanxi#wri t Building configuration...
