RcvUndersizePkts
RMON etherStatsUndersizePkts
RMON etherHistoryUndersizePkts
The total number of valid frames received
that are less than 64 bytes long (including
the FCS) and do not have any error. SFD
must be received so that the FCS can be
calculated.
14
RcvOversizePkts
RMON etherStatsOversizePkts
RMON etherHistoryOversizePkts
E-like MIB dot3StatsFrameTooLongs
The total number of packets received that
are greater than 1518 (1522 when VLAN
set) bytes long (including the FCS) and do
not have any error. SFD must be received
so that the FCS can be calculated.
18
RcvFragments
RMON etherStatsFragments
RMON etherHistoryFragments
The number of packets received that are
less than 64 bytes (not including the
preamble or SFD) and have either an FCS
error or an alignment error.
1C
RcvJabbers
RMON etherStatsJabbers
RMON etherHistoryJabbers
The number of packets received that are
greater than 1518 (1522 when VLAN set)
bytes long and have either an FCS error or
an alignment error.
20
RcvUnicastPkts
MIB-II ifInUcastPkts
The number of valid frames received that
are not addressed to a multicast address
or a broadcast address. This counter does
not include errored unicast packets.
24
RcvAlignmentErrors
E-like MIB dot3StatsAlignmentErrors
The number of packets received that are
between 64 and 1518 (1522 when VLAN
set) bytes (excluding preamble/SFD but
including FCS), inclusive, and have a bad
FCS with non-integral number of bytes.
28
RcvFCSErrors
E-like MIB dot3StatsFCSErrors
The total number of packets received that
are between 64 and 1518 (1522 when
VLAN set) bytes (excluding preamble/SFD
but including FCS), inclusive, and have a
bad FCS with an integral number of bytes.
This counter will also count packets with a
correct FCS if RX_ER occurs when valid
carrier RX_DV is present.
2C
RcvGoodOctets
RMON hostInOctets
RMON hostTimeInOctets
The total number of bytes received by a
port. Bytes are 8-bit quantities received
after the SFD. This does not include
preamble or bytes from erroneous
packets, but does include the FCS.
30
RcvMACCtrl
802.3x aMACControlFramesReceived
The total number of valid frames received
with a lengthOrType field value equal to
8808h.
34
RcvFlowCtrl
802.3x
aPAUSEMACCtrlFramesReceived
The total number of valid frames received
with (1) a lengthOrType field value equal to
8808h and (2) an opcode equal to 1.
40
RcvPkts64Octets
RMON etherStatsPkts64Octets
The total number of packets (including
error packets) that are 64 bytes long.
44
RcvPkts65to127Octets
RMON etherStatsPkts65to127Octets
The total number of packets (including
error packets) that are 65 bytes to 127
bytes long, inclusive.
