Hello everyone!

I'm simply trying to put a PRIO inside an HTB (used to throttle). I've got 
interactive traffic on the network that I want to give priority (VoIP + 
Citrix + Video).

I've used the filters in a CBQ script fine, but am having trouble 
adjusting them to this setup such that they properly assign the traffic.

tc qdisc del root dev $e

tc qdisc add dev $e root handle 1: htb default 3

tc class add dev $e parent 1: classid 1:1 htb rate $wanRate

# now that we've throttled the interface, we create the PRIO queue
tc qdisc add dev $e parent 1:1 handle 10: prio
# instantly creates classes 10:1, 10:2, 10:2

tc qdisc add dev $e parent 10:1 handle 1: pfifo
tc qdisc add dev $e parent 10:2 handle 2: pfifo
tc qdisc add dev $e parent 10:3 handle 3: sfq

############### VoIP ################

# IAX # this is the old format - IAX2 should be what's really seen going 
on
tc filter add dev $e protocol ip parent 10: prio 1 u32 match ip sport 5036 
0xffff flowid 10:1
tc filter add dev $e protocol ip parent 10: prio 1 u32 match ip dport 5036 
0xffff flowid 10:1

# IAX2 #
tc filter add dev $e protocol ip parent 10: prio 1 u32 match ip sport 4569 
0xffff flowid 10:1
tc filter add dev $e protocol ip parent 10: prio 1 u32 match ip dport 4569 
0xffff flowid 10:1

# match icmp echo request
tc filter add dev $e protocol ip parent 10: prio 1 u32 match ip icmp_type 
0x08 0xff flowid 10:1

# match icmp echo reply
tc filter add dev $e protocol ip parent 10: prio 1 u32 match ip icmp_type 
0x00 0xff flowid 10:1

## etc...........

TIA!

Hello everyone!

I'm simply trying to put a PRIO inside an HTB (used to throttle). I've got
interactive traffic on the network that I want to give priority (VoIP +
Citrix + Video).

I've used the filters in a CBQ script fine, but am having trouble adjusting
them to this setup such that they properly assign the traffic.

tc qdisc del root dev $e

tc qdisc add dev $e root handle 1: htb default 3

tc class add dev $e parent 1: classid 1:1 htb rate $wanRate

# now that we've throttled the interface, we create the PRIO queue
tc qdisc add dev $e parent 1:1 handle 10: prio
# instantly creates classes 10:1, 10:2, 10:2

tc qdisc add dev $e parent 10:1 handle 1: pfifo
tc qdisc add dev $e parent 10:2 handle 2: pfifo
tc qdisc add dev $e parent 10:3 handle 3: sfq
</snip>

Fixed! The problem is that htb was not seeing any of the rules that I
applied to the lower stuff, so it wasn't forwarding traffic there.

The fix:

tc qdisc add dev $e root handle 1: htb default 1

By saying default 1, all htb traffic gets forwarded to classid 1:1, which
has the PRIO queue attached.

Where do you redirect the traffic to the prio qdisc ??????
