This report displays Ethernet statistics.]

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.

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.
