Confirming the Serial Interface Status
Follow these steps to confirm the status of the serial interface:
Step 1 From the privileged EXEC command mode, enter the show interface serial0
command. You should see command output similar to the following:
Router# show interface serial0
Serial0 is up, line protocol is up
Hardware is PQUICC Serial in async mode (TTY1)
Internet address is 12.0.0.2/8
MTU 1500 bytes, BW 19 Kbit, DLY 100000 usec, rely 255/255, load
1/255
Encapsulation PPP, loopback not set, keepalive not set
DTR is pulsed for 5 seconds on reset
LCP Open
Listen: CDPCP
Open: IPCP
Last input 00:00:01, output 00:00:01, output hang never
Last clearing of "show interface" counters never
Input queue: 0/10/0 (size/max/drops); Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/1000/64/0 (size/max total/threshold/drops)
Conversations 0/1/256 (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
20 packets input, 1605 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
4 input errors, 0 CRC, 4 frame, 0 overrun, 0 ignored, 0 abort
23 packets output, 2403 bytes, 0 underruns
0 output errors, 0 collisions, 1 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
Step 2 Confirm that the “LCP Open” line appears in the command output.
Step 3 To continue configuration, reenter global configuration mode.
