Ethernet Statistics Report

Table 12–22.Ethernet Statistics Report

Parameter

Description

Received Packet Information

packets rcvd

Total Ethernet packets received.

discarded, RX ring empty

Discarded received packets because the internal
Received Packet Ring Pool Buffers are empty;
therefore no incoming packets could be processed.

discarded, unrecognized
protocol

Protocol Type field value in Ethernet header does
not correspond to IP.

discarded, RX error

No. of discarded received packets due to the
following reasons:

alignment errors

Frames containing a no. of bits not divisible by eight
is received and discarded.

bad fcs

Received frame contains CRC errors in the header.

runt

Received frame is smaller than the minimum
defined for this interface.

giant

Received frame lengths are greater than maximum
defined for this interface.

late collision

Discarded frames because a collision occurred
during frame reception. No. of times that a collision
is detected on a particular interface later than 512
bit-times into the transmission of a packet.

overrun

Discarded received packets due to the internal
Received Packet Ring Pool are full; therefore no
incoming packets could be processed.

Sent Packet Information

packets sent

Total Ethernet packets sent.

discarded, TX ring full

Discarded outgoing packets due to internal
Transmitted Packet Ring Pool Buffers are full.
Could not process any outgoing packets.

discarded, bad pkt

Length of outgoing packets is larger than the
maximum length of this interface.

discarded, TX error

No. of discarded transmitted packets due to:

heartbeat lost

No. of transmitting Heartbeat (signal-quality error)
packets lost/errors.

deferred

A count of frames for which the first transmission
attempts on a particular interface is delayed
because the medium is busy. The count
represented by an instance of this object does not
include frames involved in collisions.

late collision

Discarded transmitted frames because a collision
occurred. No. of times that a collision is detected on
a particular interface later than 512 bit-times into
the transmission of a packet.

excessive collision

A count of frames for which transmission on a
particular interface fails due to excessive collision
