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