This OID holds the Relative Name (Rn) of a destination class entry describing how a policy is allowed to overwrite objects of a given managed-object class — the single naming component that, appended to its parent's DN, distinguishes this policy destination class instance from its sibling instances under the same parent. Monitoring software combines this Rn with the parent path to reconstruct the object's full DN, which matters when several policy destination class instances exist side by side under the same UCS container. For example, when cucsPolicyPolicyDestClassRn returns a short token such as "policy-dest-class", that token is concatenated onto the parent's DN to form the complete address used elsewhere in the MIB for this policy destination class instance.
