How do you implement a peak shaping QoS policy on the Cisco ME 3600X. My aim to shape a service instance but to allow the shaper to burst over the shape value to a specified amount, if there is available bandwidth on the physical interface, queing any excess traffic.
I am trying to implement the policy below, except with a shape peak instead of average. However, I don't see the peak keyword under the shape command. I do see the following mentioned in the configuration guide however,"
shape average{target bps | percentvalue}
Enter percent value to set the percentage of interface bandwidth for peak information rate. The range is 0 to 100 percent. The percentage is based on the port operational link speed. Setting the percent to 0 disables shaping.
I am not sure how to use this to implement my requirements.
If there is not a way to do this using shaping, then can I use policing instead?
