Hi all,
I am running linux-2.4.0 with
3 interfaces - eth0, eth1, and eth2.
eth0 is the outgoing WAN interface.
eth1 and eth2 are the internal LAN interfaces.
eth1 and eth2 belong to a bridge group br0.
eth1 is connected to a voice-over-ip phone.
eth2 is connected to a pc.
so, the setup is
------------------------------
| |
voip-phone --->| eth1 ---> |
| br0 eth0 -|---WAN
lan-pc ---------->| eth2 ----> |
------------------------------
voip-phone can talk with lan-pc
through-the-bridge-group.
voip phone can also talk with any other
phone in the outside-world-through-the-WAN.
I need to setup QoS so that all packets
from voip-phone (that is destined to either
eth1, eth2 or to eth0) are provided with
high-priority-low-delay service. voip-phone
can be on any lan-interface (eth1 or eth2).
The only thing that can be surely said
about the voip-phone is that it will
have only a particular set of ip addresses
ranging from 171.72.233.100 to 171.72.233.200.
To implement this, i downloaded the
iproute2+tc tool version
iproute2-2.2.4-now-ss991023.tar.gz
and went through the README files.
Can somebody please help me in
writing the commands? That will
be of great help.
Thanking you in advance,
ravi

Hi Ravi, First you must know what port is used on voip. To check the correct port of voip, you can use Etherreal, tcpdump or Sniffer. I guess it is the same as H.323 on MS NetMeeting used with UDP port 1720. Port 1720 = 0x06B8. In here we use priority and simple FIFO queuing. Both queuing are used in ordinary Cisco Routers. Below is the commands: ------------------------------ ###### To control eth0 ###### #Create Priority queuing (minimum 3 bands) tc qdisc add dev eth0 root handle 1: prio bands 3 priomap 0 1 2 #Create FIFO queuing and attach to priority queuing tc qdisc add dev eth0 parent 1:1 handle 2: pfifo limit 1024 tc qdisc add dev eth0 parent 1:2 handle 3: pfifo limit 1024 tc qdisc add dev eth0 parent 1:3 handle 4: pfifo limit 1024 #Installing a u32 classifier for the traffic #In Cisco router ''tc filter'' command has same function as access-list tc filter add dev eth0 parent 1:0 protocol ip prio 1 u32 divisor 1 # Filter UDP traffic which has destination port 1720 (0x06B8) and direct # this traffic to class 1:1 (FIFO priority 1) tc filter add dev eth0 parent 1:0 prio 1 u32 match udp src 0x06B8 0xffff \ flowid 1:1 # Filter UDP traffic which has source port 1720 (0x06B8) and direct this # traffic to class 1:1 (FIFO priority 1) tc filter add dev eth0 parent 1:0 prio 1 u32 match udp dst 0x06B8 0xffff \ flowid 1:1 ###### To control eth1 ###### #Create Priority queuing (minimum 3 bands) tc qdisc add dev eth1 root handle 1: prio bands 3 priomap 0 1 2 #Create FIFO queuing and attach to priority queuing tc qdisc add dev eth1 parent 1:1 handle 2: pfifo limit 1024 tc qdisc add dev eth1 parent 1:2 handle 3: pfifo limit 1024 tc qdisc add dev eth1 parent 1:3 handle 4: pfifo limit 1024 #Installing a u32 classifier for the traffic #In Cisco router ''tc filter'' command has same function as access-list tc filter add dev eth1 parent 1:0 protocol ip prio 1 u32 divisor 1 # Filter UDP traffic which has destination port 1720 (0x06B8) and direct # this traffic to class 1:1 (FIFO priority 1) tc filter add dev eth1 parent 1:0 prio 1 u32 match udp src 0x06B8 0xffff \ flowid 1:1 # Filter UDP traffic which has source port 1720 (0x06B8) and direct this # traffic to class 1:1 (FIFO priority 1) tc filter add dev eth1 parent 1:0 prio 1 u32 match udp dst 0x06B8 0xffff \ flowid 1:1 ###### To control eth2 ###### #Create Priority queuing (minimum 3 bands) tc qdisc add dev eth2 root handle 1: prio bands 3 priomap 0 1 2 #Create FIFO queuing and attach to priority queuing tc qdisc add dev eth2 parent 1:1 handle 2: pfifo limit 1024 tc qdisc add dev eth2 parent 1:2 handle 3: pfifo limit 1024 tc qdisc add dev eth2 parent 1:3 handle 4: pfifo limit 1024 #Installing a u32 classifier for the traffic #In Cisco router ''tc filter'' command has same function as access-list tc filter add dev eth2 parent 1:0 protocol ip prio 1 u32 divisor 1 # Filter UDP traffic which has destination port 1720 (0x06B8) and direct # this traffic to class 1:1 (FIFO priority 1) tc filter add dev eth2 parent 1:0 prio 1 u32 match udp src 0x06B8 0xffff \ flowid 1:1 # Filter UDP traffic which has source port 1720 (0x06B8) and direct this # traffic to class 1:1 (FIFO priority 1) tc filter add dev eth2 parent 1:0 prio 1 u32 match udp dst 0x06B8 0xffff \ flowid 1:1 ------------------------------ I haven''t tried it before.

Hi, One more requirement is the following:- All the packets from the voip source (with a particular ip address, with a particular source, arriving on a particular interface) must have the TOS byte changed to the value 0x06, can u let me know how to do this please?
