Wiki reads as a set of examples. First uses, "add" after that "change". > therefore when I also try to incorperate loss: > tcq disc add dev ath0 root netem loss .1% > > I get: > RTNETLINK answers: File exists > > Is it possible to use two qdiscs on the same interface? > No, but netem is "classful" so you can put xcp inside netem.
