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. |

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
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.
