easy... you can erase your tc config at the root level :
# tc qdisc del $device root
That will erase the main qdisc discipline in $device. Since all classes,
cbqs/sfqs , filters, etc. hang from that one , all of them will be removed
too.

I''d like to be able to wipe out all classes and/or filters (like doing an ipchains -F for packet filter rules) quickly at the beginning of my scripts. Is there a way to do this that I''m not aware of? -- Michael T. Babcock CTO, FibreSpeed

Is there a way to do this that I''m not aware of?You can do so by deleting the root qdisc for each device. Thus, supposing some configuration similar to the following, qdisc cbq 1: dev eth1 rate 100Mbit (bounded,isolated) prio no-transmit qdisc cbq 2: dev eth2 rate 100Mbit (bounded,isolated) prio no-transmit you can delete the root qdisc from each device with this command: # tc qdisc del dev eth1 root # tc qdisc del dev eth2 root Everything that depends on the root qdisc (which, IIRC, is indeed everything) will be deleted when the root qdisc is deleted.
