IfOperStatus The current operational state of the
interface. The testing(3) state indi-
cates that no operational packets
can be passed.
• up(1) -- ready to pass packets
• down(2)
• testing(3) -- in some test mode
Read-only The EtherLoop interface status
is the PortEnabled value as
returned by the extent GetPort-
Info (GeneralOp).
The Ethernet interface status is
the EnetLinkStatus value as
returned by the extent GetMo-
demInfo (GenreralOp).
The status testing (3) is not
applicable.
IfLastChange 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.
Read-only Initially 0 for all interfaces. If an
interface changes its state, it
will indicate the time for which
the interface has been in that
state.
IfInOctets The total number of octets received
on the interface, including framing
characters.
Read-only For the EtherLoop interface, it
is the value of receive_bytes
(HDLCRxBytes) as returned by
the extent GetPortInfo (Gener-
alOp).
For the Ethernet interface, it is
the value of receive_byte_count
(EnetRxByteCount) as returned
by the extent GetModem-
Info(GeneralOp).
IfInUcastPkts The number of subnetwork-unicast
packets delivered to a higher-layer
protocol.
Read-only Not applicable.
IfInNUcastPkts The number of non-unicast (i.e.,
subnetwork-broadcast or subnet-
work-multicast) packets delivered
to a higher-layer protocol.
Read-only Not applicable.
IfInDiscards 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 proto-
col. One possible reason for dis-
carding such a packet could be to
free up buffer space.
Read-only For the EtherLoop interface, it
is the value of
discard_frames(HDLCDiscard-
Frames) as returned by the
extent GetPortInfo(GeneralOp).
Not implemented for the Ether-
net interface.
