DESCRIPTION
"The type of interface, distinguished according to
the physical/link protocol(s) immediately `below'
the network layer in the protocol stack."
::= { ifEntry 3 }
ifMtu OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The size of the largest datagram which can be
sent/received on the interface, specified in
octets. For interfaces that are used for
transmitting network datagrams, this is the size
of the largest network datagram that can be sent
on the interface."
::= { ifEntry 4 }
ifSpeed OBJECT-TYPE
SYNTAX Gauge
ACCESS read-only
STATUS mandatory
DESCRIPTION
"An estimate of the interface's current bandwidth
in bits per second. For interfaces which do not
vary in bandwidth or for those where no accurate
estimation can be made, this object should contain
the nominal bandwidth."
::= { ifEntry 5 }
ifPhysAddress OBJECT-TYPE
SYNTAX PhysAddress
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The interface's address at the protocol layer
immediately `below' the network layer in the
protocol stack. For interfaces which do not have
such an address (e.g., a serial line), this object
should contain an octet string of zero length."
::= { ifEntry 6 }
ifAdminStatus OBJECT-TYPE
SYNTAX INTEGER {
up(1), -- ready to pass packets
down(2),
testing(3) -- in some test mode
}
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The desired state of the interface. The
testing(3) state indicates that no operational
packets can be passed."
::= { ifEntry 7 }
ifOperStatus OBJECT-TYPE
SYNTAX INTEGER {
up(1), -- ready to pass packets
down(2),
testing(3) -- in some test mode
}
ACCESS read-only

"The current operational state of the interface.
The testing(3) state indicates that no operational
packets can be passed."
::= { ifEntry 8 }
ifLastChange OBJECT-TYPE
SYNTAX TimeTicks
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The value of sysUpTime at the time the interface
entered its current operational state. If the
current state was entered prior to the last re-
initialization of the local network management
subsystem, then this object contains a zero
value."
::= { ifEntry 9 }
ifInOctets OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The total number of octets received on the
interface, including framing characters."
::= { ifEntry 10 }
ifInUcastPkts OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of subnetwork-unicast packets
delivered to a higher-layer protocol."
::= { ifEntry 11 }
ifInNUcastPkts OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of non-unicast (i.e., subnetwork-
broadcast or subnetwork-multicast) packets
delivered to a higher-layer protocol."
::= { ifEntry 12 }
ifInDiscards OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of inbound packets which were chosen
to be discarded even though no errors had been
detected to prevent their being deliverable to a
higher-layer protocol. One possible reason for
discarding such a packet could be to free up
buffer space."
::= { ifEntry 13 }
ifInErrors OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of inbound packets that contained
errors preventing them from being deliverable to a
higher-layer protocol."
::= { ifEntry 14 }
ifInUnknownProtos OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of packets received via the interface
which were discarded because of an unknown or
unsupported protocol."
::= { ifEntry 15 }
ifOutOctets OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The total number of octets transmitted out of the
interface, including framing characters."
::= { ifEntry 16 }
ifOutUcastPkts OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The total number of packets that higher-level
protocols requested be transmitted to a
subnetwork-unicast address, including those that
were discarded or not sent."
::= { ifEntry 17 }
ifOutNUcastPkts OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The total number of packets that higher-level
protocols requested be transmitted to a non-
unicast (i.e., a subnetwork-broadcast or
subnetwork-multicast) address, including those
that were discarded or not sent."
::= { ifEntry 18 }
ifOutDiscards OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of outbound packets which 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 up buffer space."
::= { ifEntry 19 }
ifOutErrors OBJECT-TYPE
SYNTAX Counter
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The number of outbound packets that could not be
transmitted because of errors."
::= { ifEntry 20 }
ifOutQLen OBJECT-TYPE
SYNTAX Gauge
ACCESS read-only
STATUS mandatory
DESCRIPTION
"The length of the output packet queue (in
packets)."
::= { ifEntry 21 }
ifSpecific OBJECT-TYPE
SYNTAX OBJECT IDENTIFIER
ACCESS read-only
STATUS mandatory
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 syntatically valid
object identifier, and any conformant
implementation of ASN.1 and BER must be able to
generate and recognize this value."
::= { ifEntry 22 }
-- 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.
atTable OBJECT-TYPE
SYNTAX SEQUENCE OF AtEntry
ACCESS not-accessible
STATUS deprecated
DESCRIPTION
"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."

atEntry OBJECT-TYPE
SYNTAX AtEntry
ACCESS not-accessible
STATUS deprecated
DESCRIPTION
"Each entry contains one NetworkAddress to
`physical' address equivalence."

interface as identified by the same value of
ifIndex."
