Index |
A unique value, greater than zero, for each interface. It
is recommended that values are assigned contiguously
starting from 1. The value for each interface sub-layer
must remain constant at least from one re-initialization of
the entity's network management system to the next re-
initialization. |
Descr |
A textual string containing information about the
interface. This string should include the name of the
manufacturer, the product name and the version of the
interface hardware/software. |
Type |
The type of interface. Additional values for ifType are
assigned by the Internet Assigned Numbers Authority (IANA),
through updating the syntax of the IANAifType textual
convention. Enumerations: - other (1)

|
Mtu |
The size of the largest packet 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. |
Speed |
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. If the
bandwidth of the interface is greater than the maximum value
reportable by this object then this object should report its
maximum value (4,294,967,295) and ifHighSpeed must be used
to report the interace's speed. For a sub-layer which has
no concept of bandwidth, this object should be zero. |
PhysAddress |
The interface's address at its protocol sub-layer. For
example, for an 802.x interface, this object normally
contains a MAC address. The interface's media-specific MIB
must define the bit and byte ordering and the format of the
value of this object. For interfaces which do not have such
an address (e.g., a serial line), this object should contain
an octet string of zero length. |
AdminStatus |
The desired state of the interface. The testing(3) state
indicates that no operational packets can be passed. When a
managed system initializes, all interfaces start with
ifAdminStatus in the down(2) state. As a result of either
explicit management action or per configuration information
retained by the managed system, ifAdminStatus is then
changed to either the up(1) or testing(3) states (or remains
in the down(2) state).
dialup(4) : dialup an interface (Bintec special)
Enumerations: - up (1)
- down (2)
- testing (3)
- dialup (4)
|
OperStatus |
The current operational state of the interface. The
testing(3) state indicates that no operational packets can
be passed. If ifAdminStatus is down(2) then ifOperStatus
should be down(2). If ifAdminStatus is changed to up(1)
then ifOperStatus should change to up(1) if the interface is
ready to transmit and receive network traffic; it should
change to dormant(5) if the interface is waiting for
external actions (such as a serial line waiting for an
incoming connection); it should remain in the down(2) state
if and only if there is a fault that prevents it from going
to the up(1) state; it should remain in the notPresent(6)
state if the interface has missing (typically, hardware)
components.
blocked(8) : dialup interface is blocked (Bintec special)
Enumerations: - up (1)
- down (2)
- testing (3)
- unknown (4)
- dormant (5)
- notPresent (6)
- lowerLayerDown (7)
- blocked (8)
|
LastChange |
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. |
InOctets |
The total number of octets received on the interface,
including framing characters.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
InUcastPkts |
The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were not addressed to a multicast
or broadcast address at this sub-layer.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
InNUcastPkts |
The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a multicast or
broadcast address at this sub-layer.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime.
This object is deprecated in favour of ifInMulticastPkts and
ifInBroadcastPkts. |
InDiscards |
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.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
InErrors |
For packet-oriented interfaces, the number of inbound
packets that contained errors preventing them from being
deliverable to a higher-layer protocol. For character-
oriented or fixed-length interfaces, the number of inbound
transmission units that contained errors preventing them
from being deliverable to a higher-layer protocol.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
InUnknownProtos |
For packet-oriented interfaces, the number of packets
received via the interface which were discarded because of
an unknown or unsupported protocol. For character-oriented
or fixed-length interfaces that support protocol
multiplexing the number of transmission units received via
the interface which were discarded because of an unknown or
unsupported protocol. For any interface that does not
support protocol multiplexing, this counter will always be
0.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
OutOctets |
The total number of octets transmitted out of the
interface, including framing characters.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
OutUcastPkts |
The total number of packets that higher-level protocols
requested be transmitted, and which were not addressed to a
multicast or broadcast address at this sub-layer, including
those that were discarded or not sent.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
OutNUcastPkts |
The total number of packets that higher-level protocols
requested be transmitted, and which were addressed to a
multicast or broadcast address at this sub-layer, including
those that were discarded or not sent.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime.
This object is deprecated in favour of ifOutMulticastPkts
and ifOutBroadcastPkts. |
OutDiscards |
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.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
OutErrors |
For packet-oriented interfaces, the number of outbound
packets that could not be transmitted because of errors.
For character-oriented or fixed-length interfaces, the
number of outbound transmission units that could not be
transmitted because of errors.
Discontinuities in the value of this counter can occur at
re-initialization of the management system, and at other
times as indicated by the value of
ifCounterDiscontinuityTime. |
OutQLen |
The length of the output packet queue (in packets). |
Specific |
A reference to MIB definitions specific to the particular
media being used to realize the interface. It is
recommended that this value point to an instance of a MIB
object in the media-specific MIB, i.e., that this object
have the semantics associated with the InstancePointer
textual convention defined in RFC 2579. In fact, it is
recommended that the media-specific MIB specify what value
ifSpecific should/can take for values of ifType. If no MIB
definitions specific to the particular media are available,
the value should be set to the OBJECT IDENTIFIER { 0 0 }. |
