Faisal, So the packets should still contain DSCP tags regardless of layer2 or layer3?
Sounds like I will need to do some packet captures. Cheers, ______________________________ Andreas Wiatowski | CEO Silo Wireless Inc.

And this works very well for us. Regards.

We have about 90 sites primarily with CCR’s of various flavours. We have yet to implement any type of QOS for our VOIP..but we are starting to feel some quality pain with a couple of our “ON NET” PBX/SIP products. I have been reading about using mangle rules to mark connections and then packets, then setting up a QUEUE tree in MT where the packet marks are prioritized. We are fully routed with no layer 2 / bridging. I’m wondering if I can accomplish the same thing by just identifying the IP of my Multi-Tenant PBX box and any traffic moving to and from…and prioritizing it as 1. Secondly, do I have to do this on every single router on my network? OR Is it a better practice to IDENTIFY DCSP or TOS, mark and prioritize that instead. Just looking for the best way to unify this across my network. Anyone have examples? Many of the examples I have seen really relate to SOHO type situations…. We are talking much larger here. Most of my transport is 200Mbps to 10Gbps between sites. Cheers, Andreas Wiatowski, CEO Silo Wireless Inc. 519-449-5656 x-600
