vrIpCosPolicyAssignment
Virtual Router Ip Cos Policy Assignment
This attribute specifies the default cosPolicyGroup component that is associated with the IpPort of every protocol port on the vrirtual router. An individual IpPort can override this default using its own cosPolicyAssignment attribute. If this attribute is empty, CoS policy groups are assigned to only those IP ports where the cosPolicyAssignment attribute under the IpPort component is non-empty.
