实验17 PPP CHAP 认证 一、【实验目的】 掌握PPP CHAP 认证的过程和配置 二、【实验拓扑】 三、【实验步骤】 步骤1 路由器的基本配置 RouterA(config)#int s2/0 RouterA(config-if)#clock rate 64000 RouterA(config-if)#ip address RouterA(config-if)#encapsulation ppp RouterB(config)#int s2/0 RouterB(config-if)#ip address RouterB(config-if)#encapsulation ppp 步骤2 配置CHAP认证 RouterA(config)#username RouterB password 0 123 RouterB(config)#username RouterA password 0 123 RouterB(config)#int s2/0 RouterB(config-if)#ppp authentication chap 步骤3 验证CHAP认证 RouterB#show interfaces serial 2/0 Serial2/0 is administratively down, line protocol is down (disabled) Hardware is HD64570 Internet address is /24 MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation PPP, loopback not set, keepalive set (10 sec) LCP Closed Closed: LEXCP, BRIDGECP, IPCP, CCP, CDPCP, LLC2, BACP Last input never, output never, output hang never Last clearing of show interface counters never Input queue: 0/75/0 (size/max/drops); Total output drops: 0 Queueing strategy: weighted fair Output queue: 0/1000/64/0 (size/max total/threshold/drops) Conversations 0/0/256 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) Available Bandwidth 96 kilobits/sec 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 0 packets input, 0 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 0 packets output, 0 bytes, 0 underruns 0 output errors, 0 collisions, 1 interface resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions DCD=down DSR=down DTR=down RTS=down CTS=down RouterB#debug ppp authentication PPP authentication debugging is on RouterB#config t Enter configuration commands, one per line.
