Hi All
I've been struggling on this for a few days now and I think I still lack
the wisdom to do this. I ask you gurus to shed some light in this.
I created a hierarchy of HTB classes and "tc filter"ed the IP's to send
them to proper ones. So far so good.
The problem is I see large bursts (internet -> inside) in default 128 Kbps
class. Normally it is around 10Kbps due to non classified ICMP packets and
the like.
The said I tried to snoop the default class. So I did
tc filter add dev eth0 parent 1: protocol ip prio 0xffff \
u32 match ip src 0.0.0.0/0 flowid 1:defa \
action mirred egress mirror dev $IFDEST
tc filter add dev ifb0 parent 1: protocol ip prio 0xffff \
u32 match ip src 0.0.0.0/0 flowid 1:defa \
action mirred egress mirror dev $IFDEST
tc filter add dev eth0 parent 1: protocol ipv6 prio 0xfffe \
u32 match ip6 src ::0/0 flowid 1:defa \
action mirred egress mirror dev $IFDEST
tc filter add dev ifb0 parent 1: protocol ipv6 prio 0xfffe \
u32 match ip6 src ::0/0 flowid 1:defa \
action mirred egress mirror dev $IFDEST
been IFDEST=dummy0
I calculate the Kbps in 'defa:' class like ("rate" stat shows 0bit!):
a=$(tc -s -d qdisc sh dev eth0|grep defa: -A 2| grep Sent|\
cut -f 3 -d " "); \
sleep 10; \
b=$(tc -s -d qdisc sh dev eth0|grep defa: -A 2| grep Sent |\
cut -f 3 -d " ");\
echo $[($b-$a)*8/10240]Kbps
I can see some bursts of 500~700Kbps about every 100 seconds!! Then it
slows to 10~15Kpbs again.
But when I "tcpdump -npi dummy0" I see only a few packets now and then!
Not the avalanche I would expect.
Why don't my filter rules grab ALL default htb class rule traffic and
send it to dummy0??
Regards
Ethy
