MIB-II (RFC1213-MIB) Address Translation Group Implementation of the Address Translation group is mandatory for all systems. Note however that this group is deprecated by MIB-II. From MIB-II and onwards, each network protocol group contains its own address translation tables. Address Translation Table The Address Translation group contains one table, which is the union across all interfaces of the translation tables for converting a NetworkAddress (for example, 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. atTable OID Description 1.3.6.1.2.1.3.1 The Address Translation tables contain the NetworkAddress to physical address equivalences. Some interfaces do not use translation tables for determining address equivalences (for example, DDN-X.25 has an algorithmic method); if all interfaces are of this type, then the Address Translation table is empty, and therefore has zero entries. atEntry OID Description Index 1.3.6.1.2.1.3.1.1 Each entry contains one NetworkAddress to physical address equivalence. atIfIndex, atNetAddress atIfIndex OID Description 1.3.6.1.2.1.3.1.1.1 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. MIB Version 3.1.x/4.1.x Reference Guide 55
