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 Object Identifier 0 0, which is a syntactically
valid object identifier, 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.
