-- the 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.

            Some interfaces do not use translation tables for
            determining address equivalences (e.g., DDN-X.25
            has an algorithmic method); if all interfaces are
            of this type, then the Address Translation table

            "The media-dependent `physical' address.

            Setting this object to a null string (one of zero
            length) has the effect of invaliding the
            corresponding entry in the atTable object.  That
            is, it effectively dissasociates the interface
            identified with said entry from the mapping
            identified with said entry.  It is an
            implementation-specific matter as to whether the
            agent removes an invalidated entry from the table.
            Accordingly, management stations must be prepared
            to receive tabular information from agents that
            corresponds to entries not currently in use.
            Proper interpretation of such entries requires
            examination of the relevant atPhysAddress object."

            Note that for some managed nodes, this object may
            take on only a subset of the values possible.
            Accordingly, it is appropriate for an agent to
