Title: Mitel 3300 QOS
Post by: tmarsh on April 22, 2013, 05:19:57 PM

What is the best way to setup Qos on a clustered network that uses separate VLans on cisco swithes and routers?

From a Mitel prespective? The phones can be set to tag their packets with layer 2 and layer 3 priority. You then need to setup you Cisco gear to work with those values on the network. DSCP default is 46 for the Mitel. Believe that is the same for voice on Cisco. Therefore any routing between VLANS need to expedite packets marked with this value. Most systems I have setup I have setup with the phones tagging their packets with layer 2 priority of 6. Therefore the layer 2 switches need to be setup to respect that value.
