I
am wanting to test our qos design behavior in a lab using two WS-C3750X-12S-S 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 WS-C3750V2-48PS-S because there isn't any other traffic being produced
on the switch.
