Conventions

The following conventions are used throughout the RMON Management Information Base (MIB)
and its companion documents.

Good Packets: Error-free packets that have a valid frame length. For example, on Ethernet,
good packets are error-free packets that are between 64 and 1518 octets long. They follow the
form defined in IEEE 802.3, Section 3.2.

Bad Packets: Bad packets are packets that have proper framing and recognized as packets, but
contain errors within the packet or have an invalid length. For example, on Ethernet, bad

Documentation

NOTE: 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

“RX FIFO Overflow Frame Drop Counter Ports

0 - 3 ($0x594 – 0x597)"

and

“TX FIFO Overflow Frame Drop Counter Ports 0 - 3 ($0x621 – 0x624)"

in

the IXF1104 MAC support this and increment when either an RX FIFO or TX FIFO overflows. If any
IXF1104 MAC programmable packet filtering is enabled, the

“RX FIFO Errored Frame Drop Counter

Ports 0 - 3 ($0x5A2 - 0x5A5)"

and

“TX FIFO Errored Frame Drop Counter Ports 0 - 3 ($0x625 – 0x629)"

increment with every frame removed in addition to the existing frames counted due to FIFO overflow.
