Description (partial)

Symptom:
A DCNM-managed fabric with the Enable Strict Config Compliance option enabled will not be able to remove non-compliant QoS configuration from managed devices. The following error message may be reported by DCNM:

"Some policy-map(s) refer to this class: remove the reference(s) and try again
ERROR: Failed to write VSH commands"

As a result, DCNM is unable to correct the configuration of this device.

Conditions:
1. DCNM-managed fabric with Enable Strict Config Compliance option enabled
2. Devices within the fabric have QoS configuration applied that does not match a DCNM policy


=====

When we have strict_cc mode, all negation commands that exist in show run, but not in intent, are treated with same priority, hence if there is any dependency, the negations could fail and will need user intervention to delete the commands.
