Known Affected Releases

5.2.3.LC

Description (partial)

Symptom:
Any traffic on physical or bundle main interface matches the class with class having cos-0 as match criteria.

Conditions:
When the policy-map is applied on physical or bundle interface and has a class that matches on COS value 0, all the traffic flowing on main interface will match that class, even though COS 0 is not valid for main interface traffic.
This is because even tough packet does not have COS value, default value of cos 0 is used for QoS classification.
