Dear list, I have setup a qdisc that I''d like to remove, but somehow it seems impossible. ----------------- Output of show: sh-2.04# tc -d qdisc show qdisc cbq 22: dev eth0 rate 100Mbit cell 8b mpu 64b (bounded,isolated) prio no-transmit/8 weight 100Mbit allot 1514b level 0 ewma 5 avpkt 1000b maxidle 1us sh-2.04# tc -d class show dev eth0 class cbq 22: root rate 100Mbit cell 8b mpu 64b (bounded,isolated) prio no-transmit/8 weight 100Mbit allot 1514b level 0 ewma 5 avpkt 1000b maxidle 1us sh-2.04# tc -d filter show dev eth0 <nothing> ----------------- If I do "tc qdisc del dev eth0 root" it says "RTNETLINK answers: No such file or directory". If I do "tc class del dev eth0 classid 22:" it says "RTNETLINK answers: Device or resource busy". Can anyone tell me how I can get rid of my qdisc and class?

This should work. Try this : tc qdisc del dev eth0 root handle 22: Stef -- stef.coene@docum.org "Using Linux as bandwidth manager" http://www.docum.org/ #lartc @ irc.oftc.net _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
Thanx, but this is what I get:
sh-2.04# tc qdisc del dev eth0 root handle 22:
RTNETLINK answers: Invalid argument
So then I did:
sh-2.04# tc qdisc del dev eth0 root help
Usage: tc qdisc [ add | del | replace | change | get ] dev STRING
[ handle QHANDLE ] [ root | ingress | parent CLASSID ]
[ estimator INTERVAL TIME_CONSTANT ]
[ [ QDISC_KIND ] [ help | OPTIONS ] ]
tc qdisc show [ dev STRING ] [ingress]
Where:
QDISC_KIND := { [p|b]fifo | tbf | prio | cbq | red | etc. }
OPTIONS := ... try tc qdisc add <desired QDISC_KIND> help
And I saw that handle is shown before root, so I tried:
sh-2.04# tc qdisc del dev eth0 handle 22: root
RTNETLINK answers: Invalid argument
It''s about to drive me mad :(
Serge.

Mhh. This should work.
Try this :

But I don''t know what you can do about it.
