Quality of Service (QoS): Managing Bandwidth More Effectively Differentiated Services Codepoint (DSCP) Mapping Message Meaning Cannot modify DSCP Policy < codepoint > - in You have attempted to map a QoS classifier to use by other qos rules. a codepoint that is already in use by other QoS classifiers. Before remapping the codepoint to a new priority, you must reconfigure the other QoS classifiers so that they do not use this codepoint. You can have multiple QoS classifiers use this same codepoint as long as it is acceptable for all such classifiers to use the same priority. Table 5-10. Error Messages Generated by DSCP Policy Changes Example of Changing the Priority Setting on a Policy When One or More Classifiers Are Currently Using the Policy Suppose that codepoint 000001 is in use by one or more classifiers. If you try to change its priority, you see a result similar to the following: Figure 5-17. Example of Trying To Change the Priority on a Policy In Use by a Classifier In this case, you would use steps similar to the following to change the priority. 1. Identify which classifiers use the codepoint you want to change. 5-37
