"THE PURPOSE OF COMPUTING IS INSIGHT, NOT NUMBERS." In this case the iperf & GNS3/Dynamips combo is just computing. ;-) ------ Original Message ------ Received: Mon, 21 Dec 2009 09:31:34 AM EST From: Rick Mur <[email protected]> To: Iwan Hoogendoorn <[email protected]>Cc: [email protected] Subject: Re: [OSL | CCIE_RS] how to use iperf with GNS3 Indeed it's to learn how technology and protocols work (on Cisco IOS), but that still doesn't make sense to use iperf then, since that is used for throughput testing and I can think of a lot of scenarios to test iperf, but none includes Dynamips :-) The only real reason I can think of is like Matt said, to test QoS policies and see queueing behavior. Which makes sense :-) Still it's a lot of effort, which you can also test with ICMP or UDP echo's with a very fast timeout. -- Regards, Rick Mur CCIE2 #21946 (R&S / Service Provider) Sr. Support Engineer – IPexpert, Inc.
