Hi Everyone,
This is a simple question but I don''t understand why the below tbf is
not
working as expected by throttling traffic to 5kbps
If I throttle a PC''s traffic using the below when traffic exceeds 5kbps
packets start getting dropped (as they should) but all traffic gets dropped.
not just the bit over 5kbps.
TC="tc add dev ppp0"
$TC parent 8001:2 handle 2: tbf rate 5kbps latency 50ms burst 1540
I can see the "dropped" counter increasing, the overlimits counter
stays the
same and there is a "backlog" counter with 21p or similar each time
which
also stays the same. To get traffic working again I have to delete the qdisc
and add it again.
What am I doing wrong ?
This is a Kubuntu machine running 2.6.14 kernel, the tbf is a leaf qdisc for a
WRR class.
Thanks in Advance
Lee
p.s. if anyone can explain what the backlog is, I can''t find it in the
docco.
