Quality of Service: Managing Bandwidth More Effectively
Differentiated Services Codepoint (DSCP) Mapping
Example of Changing the Priority Setting on a Policy
When One or More Classifiers Are Currently Using the Policy
In this example, the codepoint 000001 is in use by one or more global QoS
policies. If you try to modify the priority currently associated with the code-
point, an error message similar to the following is displayed:
Figure 5-41. Error Message for Changing the Priority on a DSCP Policy
In this case, you would use steps similar to the following to change the priority.
1. Identify the global and classifier-based QoS policies that use the codepoint
whose DSCP-priority mapping you want to change.
Figure 5-42. Identifying the QoS Policies that Use a Codepoint
HP Switch(config)# qos dscp-map 1 priority 2
Cannot modify DSCP Policy 1 - in use by other qos rules.
HP Switch(config)# show qos device-priority
