help with packet tracer 5.2

Answered Question
May 4th, 2010

I have a problem working with packet tracer the serial interface is down down , why ? I am trying to connect 2 routers, the one end has DCE attached and other is DTE.  What did I do wrong here is the display of the interface.

thanks for the help

R1#show inter ser 0/0/0
Serial0/0/0 is administratively down, line protocol is down (disabled)
  Hardware is HD64570
  Description: Link to R2
  Internet address is 192.168.10.1/30
  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 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 1158 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, 2 interface resets
     0 output buffer failures, 0 output buffers swapped out
     0 carrier transitions
     DCD=down  DSR=down  DTR=down  RTS=down  CTS=down

I have this problem too.

Thomas,

The show controllers that you attached is the DCE, look at the line in the output:

DCE V.35, clock rate 64000

Have you tried ''no shut'' on both ends of the serial connection?

Thomas,

Have you done a ''no shut'' on both sides of the serial connection?
Is the cable connected to that interface?
Do a ''sh controllers'' to check which interface is the DCE so you can set the clock rate.

The interface shows as administratively down (you need to bring it up with no shut)

only 2 serial connection on this device,

this is not a physical thing it is packet tracer how do I tell if the dce is in the correct did a show run; show interface s 0/0/0

show controller output is attached show is the other side with the show interface and show controller on that one too.

that did it the no shut on both sides worked thanks I must have spent hours trying to figure it out.

You are the best !
