Hi Rodrigo, tks for the answer. It sounds like a starting point but this is not that good if there are several filters pointing to classes with high load. In this case lower prio classes will really have higher priority.
Isn't it supposed to work as expected: delete only the right filter? May it be reported as a bug? Is it a known behavior?
tks...

Andre,
I've had the same problem when I try to remove one filter rule.
This is ocurred when you have the same prio for all filter rules. I've "solved"
my problem using diferent "prio" values in filter rules.
I don't now if this is a BUG !
Anything else ?

| tc qdisc add dev eth1 root handle 1: htb default 100
| tc class add dev eth1 parent 1: classid 1:1 htb rate 128Kbit
| tc class add dev eth1 parent 1: classid 1:2 htb rate 258Kbit
| tc class add dev eth1 parent 1: classid 1:100 htb rate 32Kbit
| tc filter add dev eth1 parent 1: protocol ip prio 1 u32 match ip src
| 10.10.10.20 match ip dst 63.63.63.63 flowid 1:1
| tc filter add dev eth1 parent 1: protocol ip prio 1 u32 match ip src
| 10.10.10.20 flowid 1:2

|
| tc filter del dev eth1 parent 1: protocol ip prio 1 u32 match ip src

|
| tks for any information...
