Hello Filemon
At first glance, your configuration looks good. From your output, it seems that all traffic conformed to the policer, and was simply transmitted. What troubles me, and what is probably central to your question, is that the rate in kbps it states is 3965118 or 3.9Gbps, which is beyond the 3Gbps of the policer. In addition, we see N/A in the Transmitted value. Note also that all the traffic is considered conforming.
I suggest you consider the following to continue troubleshooting:
- Ensure that traffic is being transmitted and is actually passing through and getting to its destination. Note that your access list is matching all IPv4 traffic. Is there any IPv6 traffic on the network?
- Reduce the police rate in the policy-map to a very low number like 1 Mbps and make the exceed action
transmit, (if this is a production network, such a configuration will not affect user traffic) and see if all of that excess traffic is still considered conforming or exceeding. This will allow you to see if it is simply a volume of traffic issue, or some misconfiguration. - I notice that you’ve applied the policer to an Ethernet Bundle. QoS on bundles is measured differently, and may actually exceed the maximum of the policer depending on how load balancing across the individual links takes place. Take a look at the following Cisco documentation to see this in detail:
I hope this has been helpful!
