Parameter Meaning
Time Last Cleared Specifies a time stamp indicating the last time statistics were
reset.
Link Status Indicates whether the Ethernet link is receiving a valid Ethernet
signal (carrier) from the attached Ethernet device. Up denotes
present, and Down denotes not present.
ifInOctets Indicates the number of bytes received since the last counter
reset.
rxTotalPkts Indicates the number of received packets.
ifInUcastPkts Indicates the number of unicast packets received since the last
counter reset.
ifInMulticastPkts Indicates the number of multicast packets received since the last
counter reset.
ifInBroadcastPkts Indicates the number of broadcast packets received since the last
counter reset.
ifInDiscards Indicates the number of inbound packets that were chosen to be
discarded, although no errors had been detected. This is to
prevent them moving to a higher-layer protocol. A possible
reason for discarding such packets is to free up buffer space.
ifInErrors Indicates the number of inbound packets (or transmission units)
that contain errors that prevent them from being delivered to a
higher-layer protocol.
ifOutOctets Indicates the number of bytes transmitted since the last counter
reset.
txTotalPkts Indicates the number of transmitted packets.
ifOutDiscards
1
Indicates the number of outbound packets which were chosen to
discard even though no errors were detected to prevent the
transmission. A possible reason for discarding such a packet
could be to free up buffer space.
ifOutErrors
1
Indicates the number of outbound packets (or transmission units)
that could not be transmitted because of errors.
ifOutUcastPkts
2
Indicates the number of unicast packets transmitted.
ifOutMulticastPkts
2
Indicates the number of multicast packets transmitted.
ifOutBroadcastPkts
2
Indicates the number of broadcast packets transmitted.
dot3StatsAlignmentErrors
2
Indicates the count of frames received on a particular interface
that are not an integral number of octets in length and do not pass
the FCS check.
dot3StatsFCSErrors Indicates the count of frames received on a particular interface
that are an integral number of octets in length but do not pass the
FCS check.
dot3StatsSingleCollisionFrames
2
Indicates the count of successfully transmitted frames on a
particular interface for which transmission is inhibited by exactly
one collision.
