Name
The textual name of the interface.  The value of this
object should be the name of the interface as assigned by
the local device and should be suitable for use in commands
entered at the device's `console'.  This might be a text
name, such as `le0' or a simple port number, such as `1',
depending on the interface naming syntax of the device.  If
several entries in the ifTable together represent a single
interface as named by the device, then each will have the
same value of ifName.  Note that for an agent which responds
to SNMP queries concerning an interface on some other
(proxied) device, then the value of ifName for such an
interface is the proxied device's local name for it.
If there is no local name, or this object is otherwise not
applicable, then this object contains a zero-length string.
InMulticastPkts
The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a multicast
address at this sub-layer.  For a MAC layer protocol, this
includes both Group and Functional addresses.
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.
InBroadcastPkts
The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a 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.
OutMulticastPkts
The total number of packets that higher-level protocols
requested be transmitted, and which were addressed to a
multicast address at this sub-layer, including those that
were discarded or not sent.  For a MAC layer protocol, this
includes both Group and Functional addresses.
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.
OutBroadcastPkts
The total number of packets that higher-level protocols
requested be transmitted, and which were addressed to a
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.
HCInOctets
The total number of octets received on the interface,
including framing characters.  This object is a 64-bit
version of ifInOctets.
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.
HCInUcastPkts
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.  This object is a
64-bit version of ifInUcastPkts.
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.
HCInMulticastPkts
The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a multicast
address at this sub-layer.  For a MAC layer protocol, this
includes both Group and Functional addresses.  This object
is a 64-bit version of ifInMulticastPkts.
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.
HCInBroadcastPkts
The number of packets, delivered by this sub-layer to a
higher (sub-)layer, which were addressed to a broadcast
address at this sub-layer.  This object is a 64-bit version
of ifInBroadcastPkts.
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.
HCOutOctets
The total number of octets transmitted out of the
interface, including framing characters.  This object is a
64-bit version of ifOutOctets.
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.
HCOutUcastPkts
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.  This object is a
64-bit version of ifOutUcastPkts.
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.
HCOutMulticastPkts
The total number of packets that higher-level protocols
requested be transmitted, and which were addressed to a
multicast address at this sub-layer, including those that
were discarded or not sent.  For a MAC layer protocol, this
includes both Group and Functional addresses.  This object
is a 64-bit version of ifOutMulticastPkts.
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.
HCOutBroadcastPkts
The total number of packets that higher-level protocols
requested be transmitted, and which were addressed to a
broadcast address at this sub-layer, including those that
were discarded or not sent.  This object is a 64-bit version
of ifOutBroadcastPkts.
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.
LinkUpDownTrapEnable
Indicates whether linkUp/linkDown traps should be generated
for this interface.
By default, this object should have the value enabled(1) for
interfaces which do not operate on 'top' of any other
interface (as defined in the ifStackTable), and disabled(2)
otherwise.
Enumerations:
  • enabled (1)
  • disabled (2)
HighSpeed
An estimate of the interface's current bandwidth in units
of 1,000,000 bits per second.  If this object reports a
value of `n' then the speed of the interface is somewhere in
the range of `n-500,000' to `n+499,999'.  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.  For a sub-layer which has no concept
of bandwidth, this object should be zero.
PromiscuousMode
This object has a value of false(2) if this interface only
accepts packets/frames that are addressed to this station.
This object has a value of true(1) when the station accepts
all packets/frames transmitted on the media.  The value
true(1) is only legal on certain types of media.  If legal,
setting this object to a value of true(1) may require the
interface to be reset before becoming effective.
The value of ifPromiscuousMode does not affect the reception
of broadcast and multicast packets/frames by the interface.
Enumerations:
  • true (1)
  • false (2)
ConnectorPresent
This object has the value 'true(1)' if the interface
sublayer has a physical connector and the value 'false(2)'
otherwise.
Enumerations:
  • true (1)
  • false (2)
Alias
This object is an 'alias' name for the interface as
specified by a network manager, and provides a non-volatile
'handle' for the interface.
On the first instantiation of an interface, the value of
ifAlias associated with that interface is the zero-length
string.  As and when a value is written into an instance of
ifAlias through a network management set operation, then the
agent must retain the supplied value in the ifAlias instance
associated with the same interface for as long as that
interface remains instantiated, including across all re-
initializations/reboots of the network management system,
including those which result in a change of the interface's
ifIndex value.
An example of the value which a network manager might store
in this object for a WAN interface is the (Telco's) circuit
number/identifier of the interface.
Some agents may support write-access only for interfaces
having particular values of ifType.  An agent which supports
write access to this object is required to keep the value in
non-volatile storage, but it may limit the length of new
values depending on how much storage is already occupied by
the current values for other interfaces.
CounterDiscontinuityTime
The value of sysUpTime on the most recent occasion at which
any one or more of this interface's counters suffered a
discontinuity.  The relevant counters are the specific
instances associated with this interface of any Counter32 or
Counter64 object contained in the ifTable or ifXTable.  If
no such discontinuities have occurred since the last re-
initialization of the local management subsystem, then this
object contains a zero value.
