Hi,
I found that the link utilization is very high at the serial interface.
Serial0/0/0 is up, line protocol is up
Hardware is GT96K Serial
Description: E1 PPP to CNHNGPEEDS101 Ckt ID: Asianetcom EDL-0017
Internet address is x.x.x.x/30
MTU 1500 bytes, BW 1984 Kbit, DLY 20000 usec,
reliability 255/255, txload 106/255, rxload 249/255 =========> Heavy utilized
Encapsulation PPP, LCP Open
Open: IPCP, 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 17:12:20
Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 334 ======> Pakcets drop due to circuit fully utilized
Queueing strategy: weighted fair
Output queue: 0/1000/64/334 (size/max total/threshold/drops)
Conversations 0/174/256 (active/max active/max total)
Reserved Conversations 0/0 (allocated/max allocated)
Available Bandwidth 1488 kilobits/sec
5 minute input rate 1944000 bits/sec, 464 packets/sec
5 minute output rate 828000 bits/sec, 502 packets/sec
7101691 packets input, 720372677 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
5587587 packets output, 951038153 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out
0 carrier transitions
DCD=up DSR=up DTR=up RTS=up CTS=up
I want to know what kind of traffic caused this problem. Any command for router to get that information?
Regards,
Sam

hi,
you can enable netflow using 'ip route-cache flow' on the serial interface and then use 'show ip cache flow' to view the different traffic flows going through the interface. alternatively you can use 'ip accounting output-packets' on the interface and 'show ip accounting'. netflow will show incoming flows whereas accounting will show outgoing packets.
hope this helps.
take care.
