36.11 RMON Support
The Fast Ethernet controller can automatically gather network statistics required for
RMON without the need to receive all addresses using promiscuous mode. Setting
FPSMRx[MON] enables RMON support.
The RMON statistics and their corresponding counters in the parameter RAM are described
in Table 36-5.

Table 36-5. RMON Statistics and Counters
The total number of events in which packets were detected as
dropped by the probe due to lack of resources. Note that this may
not be the number of packets dropped; it is the number of times this
condition is detected.
The total number of octets of data (including those in bad packets)
received on the network (excluding framing bits but including FCS
octets).
The total number of packets (including bad packets, broadcast
packets, and multicast packets) received.
The total number of good packets received that were directed to the
broadcast address. Note that this does not include multicast
packets.
The total number of good packets received that were directed to a
multicast address. Note that this number does not include packets
directed to the broadcast address.
The total number of packets received that had a length (excluding
framing bits but including FCS octets) of between 64 and 1518
octets, inclusive, but had either an integral number of octets (FCS
error) or a bad FCS with a non-integral number of octets (alignment
error).
The total number of packets received that were less than 64 octets
long (excluding framing bits but including FCS octets) and were
otherwise well-formed.
The total number of packets received that were longer than 1518
octets (excluding framing bits but including FCS octets) and were
otherwise well-formed.
