               ifType object defined in MIB-II's ifTable."

       DESCRIPTION
               "This data type is used as the syntax of the ifType
               object in the (updated) definition of MIB-II's
               ifTable.
               Requests for new values should be made to IANA via
               email (iana@isi.edu).

               The relationship between the assignment of ifType
               values and of OIDs to particular media-specific MIBs
               is solely the purview of IANA and is subject to change
               without notice.  Quite often, a media-specific MIB's
               OID-subtree assignment within MIB-II's 'transmission'
               subtree will be the same as its ifType value.
               However, in some circumstances this will not be the
               case, and implementors must not pre-assume any
               specific relationship between ifType values and
               transmission subtree OIDs."
