QOS implementation on 3750 switches

Posted on 2012-09-04
Last Modified: 2012-09-17
I am wanting to test our qos design behavior in a lab using two 3750x switches that are trunked together each with a laptop connected to a switch port.  I would like to create traffic across the trunk link so that i can observe what traffic is dropped in the queue when congestion occurs.  I am having a hard time creating enough traffic on the link to drop packets.  

what is the best way to create traffic just for this purpose?  Should i change some key configuration parameters (ie interface bandwidth) to make it easier to reach a point of conjestion with less traffic?

    Considering those are Gb ports you probably aren't going to be able to produce enough traffic to congest that testbed with only 2 laptops.  Whatever QoS you are trying to test lower the threshold to something radically low so a single conversation can trip it.  However I'm still not sure you are going to see anything interesting because there isn't any other traffic being produced on the switch.
