30.11 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 30-5.
Table 30-5. RMON Statistics and Counters
Statistic Description Counter
etherStatsDropEvents 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.
DISFC
etherStatsOctets The total number of octets of data (including those in bad packets)
received on the network (excluding framing bits but including FCS
octets).
OCTC
etherStatsPkts The total number of packets (including bad packets, broadcast
packets, and multicast packets) received.

etherStatsBroadcastPkts The total number of good packets received that were directed to
the broadcast address. Note that this does not include multicast
packets.
BROC
etherStatsMulticastPkts 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.
MULC
etherStatsCRCAlignErrors 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).

etherStatsUndersizePkts 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.
USPC
etherStatsOversizePkts The total number of packets received that were longer than 1518
octets (excluding framing bits but including FCS octets) and were
otherwise well-formed.
