CBWFQ on this which is unfortunately _not_
supported on this platform irrespective of the IOS being used. So in
essence, there is no way to configure a policy-map with the priority nor
You can configure one ingress queue as the priority queue by using the mls
qos srr-queue input priority-queue bandwidth global
configuration command. The priority queue should be used for traffic (such
as voice) that requires guaranteed delivery because this queue is guaranteed
part of the bandwidth regardless of the load.
SRR services the priority queue for its configured weight as specified by
the bandwidth keyword in the mls qos srr-queue input priority-queue
bandwidth global configuration command. Then, SRR shares
the remaining bandwidth with both ingress queues and services them as
specified by the weights configured with the mls qos srr-queue input
bandwidth global configuration command.
Each port supports four egress queues, one of which (queue 1) can be the
egress expedite queue. These queues are assigned to a queue-set. All traffic
exiting the switch flows through one of these four queues and is subjected
to a threshold based on the QoS label assigned to the packet.
Only queuing and scheduling can be done on the egress which will not give
you the same results as policing.
Please do go through the configuration guide outlining the QoS capabilities
of this platform:

I do not believe CBWFQ will ever be supported on the Catalyst 3750 platform. The CBWFQ is such a fancy queueing algorithm with so many degrees of freedom that it is outspokenly difficult to implement it in hardware (as every significant packet operation has to be implemented in hardware on multilayer switches). The 3750 platform does not currently have such hardware built in so CBWFQ can not come just with an IOS upgrade, and I doubt such hardware will ever be built into the Cat3750. To my best knowledge, CBWFQ was only available on high-end switch, such as Cat6500, on selected line cards.
Your link points to a documentation that explains the use of Modular QoS CLI, or MQC, to configure selected QoS features. However, that does not mean that CBWFQ is the mechanism behind the queueing. The Cat3750 supports SRR (Shaped/Shared Round Robin) only and you currently can not get any better.
We have 3 identical switches configured by someone else and would like to claim some of the Gigabit ports(G1/G2/G3/G4) for use on servers. When we try to change the wiring and configuration, we run in to connectivity issues. Attached is a des...
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
