[LARTC] Immediately drop packet for default class ini htb

[Daniel Harold L.]

Hello,

How to immediately drop packet for default class in htb ? I`m using kernel 
2.6.5+htb+imq ...
I have to immediately drop packet that flow in default class because that 
class have queue length 1000 packets before dropping packet ... :(( If queue 
packets in this class is raised to 100 packets or more then traffic out from 
the interface is slowing down (sometimes can be zero !) for a moment (about 
5-10 seconds).

Thank you for any help from all ..

Regards,

Daniel

ps. sorry for my bad English :(

Well, it all depends on how a packet ends up in your default class.
For example, if you use iptables for packet marking, you could let
iptables drop all packages that were not marked. This would be the
best way to go.

If that's not possible, you could probably try to attach another qdisc to 
your default HTB class (leaf classes can be parents for qdiscs), which 
then just drops all the packets flowing into it (any rate limiter set to a 
very low rate should do). However, that's not a very clean solution, and 
might cause other problems, I'm not sure ;-)
