Description (partial)

Data/IFC traffic coming from IPN into RL should be classified in correct class so that proper QOS buffering/scheduling policies can be applied to the traffic.

Symptom:
Data/IFC traffic arriving from the IPN will be classified incorrectly to the CPU class (iclass/oclass = 8). This will cause issues such as a remote leaf switch going out of the fabric or traffic drops in the remote leaf switch.

Conditions:
Data/IFC traffic arriving from the IPN into a remote leaf node is tagged with VLAN CoS=6.
