ifOutDiscards OID Description 1.3.6.1.2.1.2.2.1.19 The number of outbound packets that were chosen to be discarded (even though no errors had been detected) to prevent their being transmitted. One possible reason for discarding such a packet could be to free buffer space. ifOutErrors OID Description 1.3.6.1.2.1.2.2.1.20 The number of outbound packets that could not be transmitted because of errors. ifOutQLen OID Description 1.3.6.1.2.1.2.2.1.21 The length of the output packet queue (in packets). ifSpecific OID Description Note 1.3.6.1.2.1.2.2.1.22 A reference to MIB definitions specific to the particular media being used to realize the interface. For example, if the interface is realized 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 OID 0 0, which is a syntactically valid OID, and any conferment implementation of ASN.1 and BER must be able to generate and recognize this value. fei0 returns null OID. lo0 returns null OID. fc0 returns null OID. 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 onward, 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 network address (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. For example, for broadcast media, where ARP is in use, the translation table is equivalent to the ARP cache; on an X.25 network, where nonalgorithmic translation to X.121 addresses is required, the translation table contains the network address to X.121 address equivalences. atTable OID 1.3.6.1.2.1.3.1 Description The Address Translation tables contain the network address 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. 46 MIB-II (RFC1213-MIB)

MIB-II (RFC1213-MIB)
ifOutDiscards
OID
1.3.6.1.2.1.2.2.1.19
Description
The number of outbound packets that were chosen to be discarded (even though no errors
had been detected) to prevent their being transmitted. One possible reason for discarding
such a packet could be to free buffer space.
ifOutErrors
OID
1.3.6.1.2.1.2.2.1.20
Description
The number of outbound packets that could not be transmitted because of errors.
ifOutQLen
OID
1.3.6.1.2.1.2.2.1.21
Description
The length of the output packet queue (in packets).
ifSpecific
OID
1.3.6.1.2.1.2.2.1.22
Description
A reference to MIB definitions specific to the particular media being used to realize the
interface.
For example, if the interface is realized 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 OID 0 0, which is a syntactically valid OID, and any
conferment implementation of ASN.1 and BER must be able to generate and recognize
this value.
Note
fei0 returns null OID.
lo0 returns null OID.
fc0 returns null OID.
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 onward, 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 network address (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
.
For example, for broadcast media, where ARP is in use, the translation table is equivalent to the ARP
cache; on an X.25 network, where nonalgorithmic translation to X.121 addresses is required, the
translation table contains the network address to X.121 address equivalences.
atTable
OID
1.3.6.1.2.1.3.1
Description
The Address Translation tables contain the network address 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.
