Utilization ?

[ravikant_a]

Please suggest me for how should I calculate utilization on a perticular link.For e.g. The output of SHOW INT S 1/0

txload 17/255, rxload 11/255

5 minute input rate 92000 bits/sec, 20 packets/sec

5 minute output rate 138000 bits/sec, 26 packets/sec

How to calculate the link utilization at particular instance? (i.e.Load?)

Regards,

Ravikant.

Greetings!

These counter values for tx/rx load are for the duration of last five min by default.

In order to monitor the continuous link utilization you will have to install a third party software from MRTG and enable SNMP traps on the router.

This MRTG server once configured will give you graphical reports on daily, weekly and yearly basis.

Have look at: http://www.cisco.com/warp/public/477/SNMP/calculate_bandwidth_snmp.html as well.

Greetings!

To calculate Bandwidth utilization at a particular moment you will have to install some sampling engine like mrtg (www.mrtg.org). this engine will take samples and then will give you the bandwidth utilization report.

You can claculate the txload and rxload by show interface command.

The output of thei command will give you load in terms of X/255 where X is the current load and 255 is the maximum load on a particular link.

Just clear the counters once checking the output of this command.
