Error message	Description
DSCP Policy `decimal-codepoint` not configured	You have tried to configure a codepoint in a global or classifier-based QoS policy for which there is no associated priority (No-override). Use the `qos dscp-map` command to configure a priority for the codepoint, then re-enter the codepoint in the QoS configuration.
Cannot modify DSCP Policy `codepoint` - in use by other qos rules.	You have tried to configure a codepoint in a global or classifier-based QoS policy that is already in use by other QoS policies. Before remapping the codepoint to a new priority, you must first reconfigure the other QoS policies so that they do not use the current codepoint-priority mapping. You can have multiple QoS policies that use the same codepoint to mark packets as long as it is acceptable for all such policies to use the same 802.1p priority.
