[LARTC] Removing a filter/qdisc from an interface

[LARTC] Removing a filter/qdisc from an interface

[bkohlen]

I successfully used a bounded cbq to cut down outgoing bandwidth to
certain addresses on eth0:

# tc qdisc add dev eth0 root handle 10: cbq bandwidth 100Mbit avpkt 1000

# tc class add dev eth0 parent 10:0 classid 10:1 cvq bandiwdth 100Mbit
rate 100Mbit allot 1514 weight 1Mbit prio 8 maxburst 20 avpkt 1000
# tc class add dev eth0 parent 10:1 classid 10:100 cbq bandwidth 100Mbit
rate 1Mbit allot 1514 weight 10Kbit prio 1 maxburst 20 avpkt 1000
bounded
# tc qdisc add dev eth0 parent 10:100 sfq quantum 1514b perturb 15
# tc filter add dev eth0 parent 10:0 protocol ip prio 100 u32 match ip
dst 192.168.1.0/24 flowid 10:100

I basically copied this straight out of a howto - now I can't figure out
how to remove the limitations (without rebooting that is).  I was
expecting something like:

# tc filter del 10:100

or possibly

# tc class del 10:100

but clearly I don't really understand what's going on here... any
pointers?

Thanks,
Ben

I'm also just starting with traffic control stuff - so I might be wrong
- but try:

# tc qdisc del dev eth0 root
