[LARTC] tc filter and ip match

[Glaucius Djalma Pereira Junior]

hi all

people, I'm using tc and htb to create classes and do some QoS , but i
would like to know if i can do it:

after to create the classes I need to create the rules using tc filter : 

tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst
10.0.0.0/8 flowid 1:10

ok, this rule works with all packets going to 10.0.0.0/8, but how can
i write a rule using  "!" or "not" , like :

tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst
NOT 10.0.0.0/8 flowid 1:10

ps.: I would not like to use iptables and mangle table.

did you understand ?  


best regards

I am not sure if you can have a NOT in filter. But you can have 2
classes one of which is default with restriction and make the filter
pass through the other one.

If you want 10.0.0.0/8 to be unshaped by htb and the rest go to 1:10, 
don't set a default class and filter like -

tc filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip dst 
10.0.0.0/8 flowid 1:99

tc filter add dev eth0 protocol ip parent 1:0 prio 2 u32 match u32 0 0 
flowid 1:10

where 1:99 doesn't exist as an htb class.

Andy.
