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.
