Receive Counter Name
MIB Object Supported
Description of
Counter/Comments
The number of times a receive
packet was dropped due to lack of
resources. This includes the number
of times a packet was dropped due
to receive FIFO over
fl
ow and lack of
receive descriptor. This count does
not include packets that are counted
as undersize, oversize, misaligned
or bad FCS packets. When RUN=0
any packet that is not a fragment
and that passes the address match
tests causes the RcvMissPkts
counter to increment.
The total number of octets of data
received including octets from
invalid frames. This does not include
the preamble but does include the
FCS bits. The RcvOctets counter is
incremented whenever the receiver
receives an octet.
The total number of valid frames
received that are addressed to a
broadcast address. This counter
does not include errored broadcast
packets or valid multicast packets.
The total number of valid frames
received that are addressed to a
multicast address. This counter
does not include errored multicast
packets or valid broadcast packets.
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.
The total number of packets
received that are greater than the
maximum valid frame size (including
the FCS) and do not have any error.
SFD must be received so that the
FCS can be calculated.
