received good packet count
Accounting Event: receiving packets with CRC ok
and packet size between 64 and 1522 (valid
maximum packet size in spite of VLAN disabled or
enabled). Note that the RMON/MIB counter will be
locked during 4-byte continuous register-read, and
the increment (if any) is deferred until read
complete.
received bad packet count
Formal Definition: "The number of inbound packets
that contained errors preventing them from being
deliverable to a higher-layer protocol."
Accounting Events: (1) receiving valid-length
packets with CRC error, (2) receiving runt packets,
(3) receiving over-length packets
drop packet counter
Formal Definition: "The total number of events in
which packets were dropped by the probe due to
lack of resources. Note that this number is not
necessarily the number of packets dropped; it is just
the number of times this condition has been
detected."
Accounting Event: input FIFO overrun due to
SDRAM-bandwidth blocking or buffer starvation.
sent good packet count
Accounting Event: store-and-forward transmission
success without collision
