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
