This OID returns the Distinguished Name (DN) of a managed-object class that this policy structure is allowed to push settings to in Cisco UCS Manager, the full slash-delimited path string that pinpoints exactly one destination class instance in the UCS management information tree. An administrator or monitoring tool reads this DN to know precisely which destination class instance the rest of the row's data (such as its Rn, source, or FSM fields) describes, since a UCS domain can hold many destination class instances at once. For example, polling cucsPolicyDestClassDn lets a script map a returned path like ".../dest-class-1" back to the specific destination class it belongs to before correlating it with related fault or policy data.
