| Description | This object identifies the hardware chip(s) which
is (are) principally responsible for the
implementation of the PORT (PHY) function. A few
OBJECT IDENTIFIERS are identified elsewhere in
this memo. For those The assignment of additional
OBJECT IDENTIFIERs to various types of hardware
chip sets is managed by the IANA. For example,
vendors whose chip sets are not defined in this
memo may request a number from the Internet
Assigned Numbers Authority (IANA) which indicates
the assignment of a enterprise specific subtree
which, among other things, may be used to allocate
OBJECT IDENTIFIER assignments for that
enterprise's chip sets. Similarly, in the absence
of an appropriately assigned OBJECT IDENTIFIER in
this memo or in an enterprise specific subtree of
a chip vendor, a board or system vendor can
request a number for a subtree from the IANA and
make an appropriate assignment. It is desired
that, whenever possible, the same OBJECT
IDENTIFIER be used for all chips of a given type.
Consequently, the assignment made in this memo for
a chip, if any, should be used in preference to
any other assignment and the assignment made by
the chip manufacturer, if any, should be used in
preference to assignments made by users of those
chips. If the hardware chip set is unknown, the
object identifier
unknownChipSet OBJECT IDENTIFIER ::= { 0 0 }
is returned. Note that unknownChipSet is a
syntactically valid object identifier, and any
conformant implementation of ASN.1 and the BER
must be able to generate and recognize this
value. |
