Hi, you should be ble to get some QOS commands starting with the higher end of the 12.1 IOS. I have a 2524 at home with only 8M and I am running 12.1.27 and it has most of the QOS commands on it. With 24M, you should be able to get to 12.2.23e or higher. I do not believe you need a new router or more memory to achieve what you are looking for. You may want to stick with GD code though.
