Hi Arie, Using the feature navigator,
Two-Rate Three Color Policer, and Two-Rate Three Color Policer - Ingress are listed.. Supported platforms show: ME3400E CAT4500E-Sup6L CAT4900M Does this seem like the complete set of devices that have this 3 color policer option?

Peter, You most likely can apply ingress policing on the ports, creating a class per customer (matching on ACL), and policing them to their MIR rate. You could try and use a 3 color policer, marking any traffic below CIR with a higher priority, above CIR to default, and above MIR to drop (exceed traffic). Then on the uplink, give the below CIR traffic a higher priority so in case of congestion this traffic will be preferred. You need to select the right platform carefully, and you most likely would need a more advanced device than just a regular desktop switch to be able to scale...

I'm trying to adapt a QOS method we use under linux into cisco space.. Anybody got the cisco QOS fu to give me a general idea of how to do this in cisco world.. Problem: - We traffic shape wireless access points, with a single access point connected per switch port, with several customers attached to each access point - Each customer has his own subnet, but is on the same vlan, so shaping must be done by subnet - Each customer is sold a plan that has a CIR (minimum data rate) and MIR (peak data rate if resources are available), each customer may have a different plan - If the aggregate of total customer usage is less than the total access point capacity, allow them to burst above their CIR up to their MIR limit Solution: - On linux, we use HTB to do this.. The port has a root class with the total capacity of the access point configured, customers are configured with RATE= (CIR) and CEIL= (MIR) rates, along with RULE = Subnet.. It's very straightforward and works remarkably well.
