Hi, Having issues getting a replace command working correctly. The error reported is "RTNETLINK answers: Invalid argument" which isn't descriptive or helpful. The command i'm running is: tc qdisc replace dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 5kb latency 70ms The idea being to replace an sfq with handle D and hopefully limit a certain user in my WRR class. If I delete the qdisc first and add with the below line it works. tc qdisc del dev ppp0 parent 8001:D handle D: tc qdisc add dev ppp0 parent 8001:D handle D: tbf rate 5Kbit burst 1540 latency 70ms Anyone see what I'm doing wrong ? :Lee _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
