Measure capacity of Point to Point Lease line, Given by ISP

Hi Experts,

Suppose i have 5 mbps Point to point Lease line (fibre or copper) which connects two sites A and B, distance around 5 Kms.

Here i am talking about only Point to point lease line which have no internet, plz do not consider Internet Lease line.

I can easily check bandwidth of Internet Lease line but i do not know any method to test point to point LL Connectivity.

I Read out many cisco support forms but there is no any exact solution.

There are everyone suggesting only Tools and  i Know about every monitoring Tools like as

Whatsup Gold, Cacti, Ipserf,Netflow, PRTG, MRTG, Solarwind, Opmanager....

I am confuse because these above tools gives only information of Bandwidth usage report of Date-wise,Hour-wise, etc.

It does not matter for me that what is Bandwidth usage of Per day, per hour, IN and OUT traffic and whatever.

Only Point to Point lease line should be 5 Mbps....... That's it

So please solve my given below Questions =>

1. Suggest me exact tool or Method, if you have any screenshot or documentation plz share with me ?

2. How to measure P2P leased line speed/Bandwidth using ping output ?

3. Suggest me freeware tools to checkout user-wise/ip-wise status of upload and download ? i have not yet found

4. in my case, can i say "Speed" at place of "Bandwidth"....Yes or No ?

If you are fully confident and you have checked practically then revert me otherwise Plz ignore...........

Hello Kuldeep,

What i do normally, is to setup an FTP server with a file of 100 MB size and try to download it from the other end

and see how long it took to download the file.

100 MB flle take 8 seconds over 100 mbps line..

so your file should get downloaded in 160 seconds

thats an example dear..

100 MB file 100mb/s line takes 8 second to download technically

in your case you have 5 mb/s speed so it takes 160 second to download the same file

hope its clear now

Harish,

Hello Kuldeep

2. How to measure P2P leased line speed/Bandwidth using ping output ? - I dont think we can measure using PING

3. Suggest me freeware tools to checkout user-wise/ip-wise status of upload and download ? i have not yet found- Karsten has posted one which he has used. should be good..

4. in my case, can i say "Speed" at place of "Bandwidth"....i think both are same ?

I usually use the good old Iperf for this kind of tests: http://sourceforge.net/projects/iperf/

its not speed. It is capacity (bits per time interval)

you will need to take a look at tcp settings on any workstation involved. Past experience indicates that thats usually where things don't work right.
