Troubleshooting Serial Line and Frame Relay Connectivity
Here is how it is done and what the interface looks like after the command
has been issued:
Router_A#
clear counters serial 1
Clear "show interface" counters on this interface
[confirm]
%CLEAR-5-COUNTERS: Clear counter on interface Serial1 by
console
Router_A#show interface serial 1
Serial1 is up, line protocol is up
Hardware is HD64570
Internet address is 172.16.30.5/30
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/
255, load 51/255
Encapsulation HDLC, loopback not set,
keepalive set (10 sec)
Last input 00:00:00, output 00:00:00, output hang never
Last clearing of "show interface" counters 00:28:48
Input queue: 1/75/0 (size/max/drops);
Total output drops: 0
Queueing strategy: weighted fair
Output queue: 0/1000/64/0 (size/max total/threshold/
drops)
Conversations 0/2/256 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
5 minute input rate 321000 bits/sec, 48 packets/sec
5 minute output rate 320000 bits/sec, 48 packets/sec
12439 packets input, 13257786 bytes, 0 no buffer
Received 202 broadcasts, 0 runts, 0 giants, 0
throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored,
0 abort
12438 packets output, 13256434 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped
out
0 carrier transitions
