               INTEGER

          Definition:
               A unique value for each interface.  Its value ranges
               between 1 and the value of ifNumber.  The value for each
               interface must remain constant at least from one re-
               initialization of the entity's network management system
               to the next re-initialization.

          Definition:

               hardware interface.
