2. Change the classifier configurations by assigning them to a different DSCP
policy, or to an 802.1p priority, or to No-override. For example:
Delete the policy assignment for the dscp-map classifier. (That is,
a.
assign it to No-override.)
ProCurve(config)# no qos dscp-map 5
b. Create a new DSCP policy to use for re-assigning the remaining
classifiers.
ProCurve(config)# qos dscp-map 000100 priority 6
c. Assign the port-priority classifier to the new DSCP policy.
ProCurve(config)# int e d1 qos dscp 000100
3. Reconfigure the desired priority for the 000001 codepoint.
ProCurve(config)# qos dscp-map 000001 priority 4
4. You could now re-assign the classifiers to the original policy codepoint or
leave them as currently configured.
