Un able to Send packets

I am un able to send or receive packets across my WAN. Surprisingly the statics of the show interface command of routers on both ends of the WAN shown something like this.

Serial0/3 is up, line protocol is up

Hardware is PowerQUICC Serial


Internet address is

MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,

reliability 255/255, txload 1/255, rxload 1/255

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

Last input 00:00:09, output 00:00:02, output hang never

Last clearing of "show interface" counters never

Input queue: 0/75/0 (size/max/drops); Total output drops: 1701

Queueing strategy: weighted fair

Output queue: 0/1000/64/1512 (size/max total/threshold/drops)

Conversations 0/33/256 (active/max active/max total)

Reserved Conversations 0/0 (allocated/max allocated)

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

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

9583019 packets input, 753153944 bytes, 0 no buffer

Received 1473101 broadcasts, 0 runts, 9 giants, 0 throttles

111571 input errors, 57014 CRC, 39446 frame, 0 overrun,

0 ignored, 15111 abort 9905485 packets output, 2070404869 bytes, 0


0 output errors, 0 collisions, 82453 interface resets

0 output buffer failures, 0 output buffers swapped out

9905485 packets output, 2070404869 bytes, 0 underruns

1876 carrier transitions

DCD=up DSR=up DTR=up RTS=up CTS=up

On the other end of the WAN the Serial interface of the router has as its ip address and interface statics show that the line protocol is up as well.

Would anyone know what could be causing this surprising scenario?

Re: Un able to Send packets


See the huge CRC errors and many carrier transitions. You cannot expect a single packet to travel at this condition. Get in touch with your line provider and sought out the problem .There may be loose contacts at the jumpering points or some other induction problem at your circuit.

I would say that your link does not seem to be functioning.
