Re: [LARTC] Is local originated traffic affected?

[Sorin Panca <sorin.panca@gmail.com>]

I posted earlier today and i forgot to attach the rules I used...
The problem was that when I apply them, the router gets isolated
from both the Internet and the LAN.
I'm sorry I reply to my post!
I don't know if this behaviour is normal.
Here are my rules...

leaf="sfq perturb 10"
BURST="50k"
CBURST="150k"

# Deleting old qdiscs:
$tc qdisc del dev $EXT1 root &>/dev/null
$tc qdisc del dev $INT1 root &>/dev/null

# Adding three root classes: class 1:A = LAN (100 Mbit/s)  MARK = 0x2;
# class 1:B = MAN (1 Mbit/s) MARK = 0x1; class 1:C = Internet (256 kbit/s)
# Also the packets have the TOS field altered by the iptables-script so
# that they are either Minimized-Delay or Maximize-Throughput based on
# their length.

for DEV in ` echo $INT1 $EXT1 `; do
   $tc qdisc add dev $DEV root handle 1: htb default FF

 # Class MAN
   $tc class add dev $DEV parent 1: classid 1:B htb \
	rate $ROOT_MAN_RATE$kbit ceil $ROOT_MAN_CEIL$kbit \
	burst $BURST cburst $CBURST

 # Class Internet
   $tc class add dev $DEV parent 1: classid 1:C htb \
	rate $ROOT_NET_RATE$kbit ceil $ROOT_NET_CEIL$kbit \
	burst $BURST cburst $CBURST

 # Class default
   $tc class add dev $DEV parent 1: classid 1:FF htb \
	rate $BULK_NET_RATE$kbit ceil $BULK_NET_CEIL$kbit
   $tc qdisc add dev $DEV parent 1:FF handle FF: $leaf

done

		rate $NETRATE ceil $NETCEIL \
		burst $BURST cburst $CBURST &>/dev/null
            $tc qdisc add dev $DEV parent 1:C$hIP handle C$hIP: \
		$leaf &>/dev/null
        done

    $tc filter add dev $INT1 parent 1: protocol ip prio 1 u32 \
	match ip dst $MAXIP/32 \

done

Tank you in advance!
