SPI3 interface before the EOP is received. Packets sizes below this threshold are treated
as “store and forward.” Once a packet size exceeds the RX FIFO transfer threshold, it can
no longer be dropped by the RX FIFO even if it is marked to be dropped by the MAC.
RMON Statistics Support
The IXF1104 MAC supplies RMON statistics through the CPU interface. These statistics are
available in the form of counter values that can be accessed at specific addresses in the
register maps
and begin counting from zero. A separate set of RMON statistics is available for each MAC
device in the IXF1104 MAC.
Implementation of the RMON Statistics block is similar to the functionality provided by
existing Cortina switch and router products. This implementation allows the IXF1104 MAC
to provide all of the RMON Statistics group as defined by RFC2819. The IXF1104 MAC
supports the RMON RFC2819 Group 1 statistics counters.
and additional statistics registers supported by the IXF1104 MAC that are outside the scope
of the RMON RFC2819 document.

RMON Ethernet Statistics
Group 1 Statistics
The RMON specification requires that this is, “The total number of events where packets were dropped by
the probe due to a lack of resources. This number is not necessarily the number of packets dropped; it is
the number of times this condition is detected. The

notes the differences
See table note 1
The IXF1104 MAC
has two counters for
receive and transmit
that use different
naming conventions
for the total Octets
and Octets Bad.
These counters
must be combined to
meet the RMON
definition for this
statistic.
