How to make a qos policy, thats serves 6 class of traffic on Cisco 3845 one by one?

Hello.

We have a buisses task to make some qos policy in our mpls backborn that consist of Cisco 3845 Version 15.1(1)T. We have six class of traffic + NC:

1) - NC

2) orange class

3) yellow class

4) green class

5) blue class

6) purple class

7) best-effort 

And we have 3Mbit\s links. We can't use bandwidth parametr, couse any class of traffic can use full bandwidth, but while congestion orage class should take 3Mbit\s no matter if other traffic. If there is no orange, yellow should take full bandwidth no matter if other traffic, and etc.

I tryed to use WRED, queue-limit but no any results. 

 

What strategy should i take to solve problem?

 

PS sorry for bad English.

From what I think you're describing, old PQ (priority queuing - don't confuse with PQ on switches) would be what you want.  However, don't know if its still provided with 15.x IOS and it only supports 4 classes.
