Bandwidth Utilization between two routers

Hi guys,

We are having two routers in diffrent locatons. Right now i want to check the Bandwidth utilization of the routers.

Is there is any tools are available in cisco to check the bandwidth.

Thanks in advance.

use PRTG Free tool .no free tool in cisco

Re: Bandwidth Utilization between two routers

You can actually see a snapshot of the utilization by doing "show interface xyz" for your interface between the routers. If RouterA used Serial0/0 to connect to Serial0/1 on RouterB, you could do: RouterA# show interface serial0/0

You would see something like:

RouterA#show interface serial1/0
Serial0/0 is up, line protocol is up
  Hardware is DSXPNM Serial
  Internet address is x.x.x.x/30
  MTU 4470 bytes, BW 44210 Kbit/sec, DLY 200 usec,
     reliability 255/255, txload 107/255, rxload 44/255
  Encapsulation HDLC, crc 16, 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 never
  Input queue: 0/75/144418/0 (size/max/drops/flushes); Total output drops: 28238450
  Queueing strategy: fifo
  Output queue: 0/40 (size/max)
  30 second input rate 7784000 bits/sec, 1917 packets/sec
  30 second output rate 18710000 bits/sec, 2720 packets/sec
     3985575203 packets input, 4114474167 bytes, 962 no buffer
     Received 1429313 broadcasts, 0 runts, 0 giants, 0 throttles
     3273 input errors, 3273 CRC, 623 frame, 253 overrun, 0 ignored, 472 abort
     1632477877 packets output, 1915617409 bytes, 0 underruns
     0 output errors, 0 collisions, 34 interface resets
     0 unknown protocol drops
     0 output buffer failures, 0 output buffers swapped out
     1 carrier transitions
DSU mode 0, bandwidth 44210, real bandwidth 44210, scramble 0

The bolded lines give you a snapshot of the bits/sec. Here my inbound is 7784000/1024 = 7601kbits/s or 7.601megabit/s. Outbound is 18710000 / 1024 = 18271 kbits/s, or 18.271 megabits/s. The best thing to do to keep historical data is to use Cacti or MRTG or PRTG or any other SNMP polling device to capture this data.
