I'm trying to setup Qos on my companies smallish network. I'm not new to networking (not a guru either) but definitely new to Qos.
-We have about 30 users and each user has a PoE Voip phone as well has Desktop computer.
-The desktops connect to the phones as passthrough and the phones have the connection from the poe switch (Adtran Netvanta 1544).
-The Netvanta 1544 switch hooks up to a Dell 5324 Switch. We have 2 of these that handle switching for the rest of the devices on the network (copiers, fax server, windows server, etc.)
-Also, we have a Sonicwall NSA 2400 connected to the Dell switches. That is the gateway.
-The Sonicwall NSA 2400 connects to an Adtran Total access 908e. I guess this device is the true gatway but it passes the public Ip addresses to the Sonicwall 2400.
-I've looked at the Dell switchs and they have default Qos Settings, the Netvanta switch has default CoS setup (no Qos options but I don't know the real difference to be honest). However, the router has no Qos tagging enabled on any interface. Are getting true Qos from web traffic if this is not enabled?
-Sorry for the long post here but it's best if you understand the whole picture.
-Our Qos needs are pretty simple. We use a web application as a main application and voip is obviously important but we'd like to put less priority on stuff like Youtube (web video streaming).
