I am looking for a way to prioritize traffic on my network. I have a CISCO 861 running ISO version 12.4(15r)XZ2. I want to do it by IP address first, maybe later by port. I know to use QoS but when I search the internet, there are just so many ways to do it just made me more confused. Can anyone help with this, or point me in the direction that I can read and learn how to do such a thing? Again, I know it is possible and I don't want to limit the bandwidth, just make it so a particular IP / Server has priority.
