The > rate is used when you have 2 or more child classes with the same parent. I would like to believe you but I observe even with one class, that traffic is decreasing to something around 60kbit. Is there something I am doing wrong ? BTW looking into the howto I wonder if it is a good idea to set ceil for ingress to the maximum rate I get. -- Thomas _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
