How To Implement QoS (Bandwith Limit)

[CSCO12001340]

Hi,

I have a topology like in the figure below. I want to limit the traffic of the PCs up to maximum 1 mpbs seperately. I mean 10.10.41.10 , 10.10.41.35 and 10.10.41.57 should use just up to 1 mbps seperately when they try to reach 10.10.25.0/24 network. I would like to do it on Router-1. How can I create a QoS policy, can you please give me a configuration example as well ?

For both ingress and egress to the hosts? I also also assume the 1 Mbps is a limit on ingress or egress, not an aggregate for both combined.

On R1's you can implement CBWFQ policies, for ingress and/or egress to limit specific host aggregate bandwidth usage. You might have an ingress/egress policy on f0/0 or f0/1, an ingress policy on both or an egress policy on both.

Assuming you bandwidth limit using a policer, you can use the same policy for ingress or egress. If you use a shaper to limit bandwidth, it will need to be applied as an egress policy.

You would need one class per host. Each host class can use the same class-map which can also use the same ACL to match host IPs.

I'm guessing this might be a student assignment, so I'm holding back on providing a specific example.

BTW, when you restrict traffic, you generally like to accomplish that as early as possible. So, for example, you might want to regulate traffic on R2's f0/0 and R1's f0/1 (or even on SW1 and SW2).
