"This data type indicates a well-known DoS type which can be detected.
Note that a particular agent may support only certain DoS attack
types. Thus, the valid values of this object are project
dependent. An agent may respond with an error
(e.g., 'inconsistentValue ') to a management SET operation which
attempts to modify the value to one which is not supported by the
managed device."
