Hi, I want to configure QoS on a Cisco's 800 and 1800 series router and I couldn't make it work the way I want. I've configured three classes of service called GOLD, SILVER and BRONZE, designed for low latency, low loss and data respectively.
* I want the GOLD class to have a maximum bandwidth of 25%, even if there is traffic in the other classes. * The SILVER class has a minimum bandwidth of 50% and, if there's no traffic in the GOLD queue, I want this class to take the available bandwidth which is not used by the GOLD class. Thats means that the SILVER class has a 50% of assured bandwidth and can increase to a maximum of 75% of the total bandwidth. * The BRONZE class has no assured bandwidth and can only take the bandwidth which is not used for the other classes. The problem is that with Cisco's QoS tools I have not reached the desired goal. I have tried with different configurations and IOS and I couldn't get any successful result . Below I attach the policy configuration that I have tried (just to give you an example). Is there any way in which I can achieve the behavior that was described above?. Thanks in advance.
