Hi Dhaval

Is it a VPN connectivity given by your ISP or a internet connectivity ?

If its a internet connectivity the best tool would be doing simultaneous downloads by directly connecting only one PC or laptop on the ethernet port of the router.

you can try downloading different files of different file sizes from different sites which may help you out to the check out the the throughput capacity of you connection.

Also you can verify the loading conditions on the interface which can tell you the input and output loads coming in and out of the line.

thanks for takin interest,

we have internet connection from VSNL itself.

and connecting PC direct to internet line is good idea, but can i do same without connecting my laptop directly, is cisco provide any command to do same....?

i tried show interface command.

Hi Dhaval

As a company we dont cap any of our customers even in our 1:4 offings.

But still as a usual recommendations you can directly connect ur pc/laptop directly onto the router port using a cross cable and access the net.

Do remember to check addressing scheme to be used on the ethernet port of the router and the pc/laptop..

You can make use of show interface serial x/x to effectively check the utilisation.

You can do a "show interface" for several times and check for the value of the 5 min input / 5 min output value. The would provide you the real time load passing through this link.

Or better yet, try to setup an MRTG application that can monitor interface traffic.

Hope this helps,

Hi Bipin,

You may use Solarwinds NPM or Cacti to monitor the per port interface graph.

Agree with Saeed... you can also use Cacti. It is a graphing tool free and it will give you bandwith utilization for the last 30 min to 24 hrs ( you can tweak settings)
