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 ---------------------------------------------------> Ravi Samprathi work:(408)853-8038 Cisco Systems res :(408)988-2268 Empowering the Internet Generation <---------------------------------------------------
