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.
correspond to IP.
discarded, RX error
No. of discarded received packets due to the following
reasons:
reasons:
alignment errors
Frames containing a no. of bits not divisible by eight is
received and discarded.
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.
for this interface.
giant
Received frame lengths are greater than maximum
defined for this interface.
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

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.

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