今天同事打来电话说,到分厂的电话 邮件都不能用了。赶快跑去机房看,设备的灯号全部正常,进去路由器一看,
Serial0/0 is up, line protocol is down
Hardware is PowerQUICC Serial
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation PPP, loopback not set
Keepalive set (10 sec)
LCP Listen, multilink Closed
Closed: CDPCP
Last input never, output 00:00:28, output hang never
Last clearing of "show interface" counters 02:33:23
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops:
Queueing strategy: fifo
Output queue :0/40 (size/max)
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, 1 runts, 0 giants, 0 throttles
51 input errors, 4 CRC, 25 frame, 0 overrun, 0 ignored, 22 abort
1840 packets output, 55200 bytes, 0 underruns
0 output errors, 0 collisions, 491 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
DCD=up DSR=up DTR=up RTS=up CTS=up
赶紧去分厂看,结果一样,叫电信网管中心做一个双向环路测试,在分厂可收到,回公司无法收到。做硬环测试MODEM,两端都正常。应该是公司这端得的路由器问题了? |
