need to know if it's possible to configure a QoS traffic shaping rule with cisco IOS by applying bandwidth LIMIT with: TRAFFIC BANDWIDTH GUARANTEES + Dynamic Bandwidth UP TO 100%.




- With catalyst 45XX and 65XX/76XX using user-based rate limiting (UBRL) I can only adopts policy to rate limit to an individual rate ?

- are there any other features available on IOS ?


- are there any other features available on other Cisco router/switch ?





In particular I need to configure a policy to dynamically balance the FULL bandwidth allocation with different streams guarantee the minimum bandwidth allowing me to get the maximum performance out of your network without sacrificing the benefits from guaranteed bandwidth to critical resources.



Example:


I've 3 IP and I need to guarantee a minimum level and also able to utilize up to 100% of the available network

capacity.



source IP 10.0.0.1 DESTINATION ANY = shaping minimum 20% garantee + possible up to 100%

source IP 10.0.0.2 DESTINATION ANY = shaping minimum 30% garantee + possible up to 100%

source IP 10.0.0.3 DESTINATION ANY = shaping minimum 10% garantee + possible up to 100%
