by an ethernet, then the value of this object refers to a document
defining objects specific to ethernet. If this information is not present,
its value should be set to the OBJECT IDENTIFIER { 0 0 }, which is a
syntactically valid object identifier, and any conforming
implementation of ASN.1 and BER must be able to generate and
recognize this value.
Address Translation Group
Implementation of the Address Translation group is mandatory for
all systems. Note however that this group is deprecated by MIB-II.
That is, it is being included solely for compatibility with MIB-I nodes,
and will most likely be excluded from MIB-III nodes. From MIB-II
and onwards, each network protocol group contains its own address
translation tables.
The Address Translation group contains one table which is the union
across all interfaces of the translation tables for converting a
NetworkAddress (e.g., an IP address) into a subnetwork-specific
address. For lack of a better term, this document refers to such a
subnetwork-specific address as a `physical' address. Examples of
such translation tables are: for broadcast media where ARP is in use,
the translation table is equivalent to the ARP cache; or, on an X.25
network where non-algorithmic translation to X.121 addresses is
required, the translation table contains the NetworkAddress to X.121
address equivalences.

Description
The interface on which this entry's equivalence is effective. The
interface identified by a particular value of this index is the same
interface as identified by the same value of ifIndex.

Description
The media-dependent `physical' address. Setting this object to a null
string (one of zero length) has the effect of invaliding the
