And I sure wish they's come clean about using RFC8290 in their design, to me anyone that publicly states they are using fq_codel is a mark of quality.... :) and I'd also like to know if the have ecn on or off. It was good, after all this time, to see this error message. http://forum.netduma.com/topic/25802-qos-rpc-error-error_cmdfail-exec-tc-qd= isc-add-dev-ppp0-parent-21-handle-3-fq_codel-failed-with-2/ --=20 Dave T=C3=A4ht CTO, TekLibre, LLC http://www.teklibre.com Tel: 1-831-205-9740
