Yes, IIRC simplest=2Eqos with cake as qdisc will use HTB as shaper and cak= e as leaf qdisc, while piece_of_cake=2Eqos will use cake both as shaper and= leaf qdisc=2E The former is only useful for comparative testing, for actua= l usage I recommend the later=2E Best Regards Sebastian > >/Jonas --=20 Sent from my Android device with K-9 Mail=2E Please excuse my brevity=2E
