Interface type

This speci®es the connector type as AUI or RJ45.

Input statistics:

failed, packet too long or failed, frame too long

The Failed, Packet Too Long counter increments when the interface receives a packet that is larger than the maximum size of 1518 bytes for an Ethernet frame. This data is exported via SNMP as the dot3StatsFrameTooLongs counter.

failed, CRC error or failed, FCS (Frame Check Sequence) error

The Failed, CRC (Cyclic Redundancy Check) Error counter increments when the interface receives a packet with a CRC error. This data is exported via SNMP as the dd3StatsFCSErrors counter.

failed, framing error or failed, alignment error

The Failed, Framing Error counter increments when the interface receives a packet whose length in bits is not a multiple of eight.

failed, FIFO over-run or failed, FIFO overrun

The Failed, FIFO (First In, First Out) Overrun counter increments when the Ethernet chipset is unable to store bytes in the local packet buffer as fast as they come off the wire.

collision in packet

The counter increments when a packet collides as the interface attempts to receive a packet, but the local packet buffer is full. This error indicates that the network has more traffic than the interface can handle.

short frame

The counter increments when the interface receives a packet with a short frame.

buffer full warnings

The Buffer Full Warnings counter increments each time the local packet buffer is full.

packets missed

The Packets Missed counter increments when the interface attempts to receive a packet, but the local packet buffer is full. This error indicates that the network has more traffic than the interface can handle.

internal mac rcv errors

Receive errors that are not late, excessive, or carrier check collisions. This data is exported via SNMP as the dot3StatsInternalMacReceiveErrors counter. This statistic is the sum of the FIFO Overruns.

Output statistics:

initially deferred or deferred transmission

The Initially Deferred counter increments when the carrier sense mechanism detects line activity causing the interface to defer transmission. This data is exported via SNMP as the dot3StatsDeferredTransmissions counter.

single collision

The Single Collision counter increments when a packet has a collision on the ®rst transmission attempt, and then successfully sends the packet on
