1.3.6.1.2.1.3 ADDRESS TRANSLATION GROUP

1

atTable

The Address Translation tables contain the NetworkAddress to `physical' 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 is empty, i.e., has zero entries.

1.1

atEntry

Each entry contains one NetworkAddress to `physical' address equivalence.

1.1.1

atIfIndex

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.

1.1.2

atPhysAddress

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.

1.1.3

atNetAddress

The NetworkAddress (e.g., the IP address) corresponding to the media-dependent `physical' address.
