| | Hi list, I'm playing with tc and found a strange behavior when I try to
| | delete filters. For example, this simple scenario:
| |
| | 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
| |
| | works just fine, but when I try to delete oen of the filters with
| | something like this:
| |
| | tc filter del dev eth1 parent 1: protocol ip prio 1 u32 match ip src
| | 10.10.10.20 flowid 1:2
| |
| | both filters are deleted.
| |
| | I've found a post from Dimitry V. Ketov in the kernel list on may/2003
| | with a situation like this one, but there are no answers.
| |
| | I'm using 2.4.23 and iptables 1.2.7a. Any clues what can be the cause?
| | I'm suposed to be able to delete filters separately right? May it be a
| bug?
| |
| | Deleting the whole qdisc is not an opition in my setup and trying to
| | delete the parent class gives me a "device or resource busy" error
| | because of the filters. tc class del doesn't seen to delete its "child"
| | filter.
| |
| | tks for any information...
| |
