transmitted to multicast addresses are not broadcast frames and are
excluded.
Directed Frames Rx
A count of directed data frames that were successfully received.
Multicast Frames Rx
A count of frames that were successfully received and are directed to an
active nonbroadcast group address. This does not include frames
received with frame-too-long, FCS, length, or alignment errors, nor frames
lost because of internal MAC sublayer errors. This counter is incremented
as indicated by the Receive OK status.
Broadcast Frames Rx
A count of frames that were successfully received and are directed to a
broadcast group address. This count does not include frames received
with frame-too-long, FCS, length, or alignment errors, nor frames lost
because of internal MAC sublayer errors. This counter is incremented as
indicated by the Receive OK status.
Frames Rx with CRC Error
The number of frames received with CRC errors.
IEEE 802.3 Statistics
This section describes the parameters in the IEEE 802.3 Statistics portion
of the General Statistics Page appears in Figure 12 on page 39.
Frames Rx with Alignment Error. A count of the frames that were not an
integral number of octets in length and do not pass the FCS check. This
counter is incremented when the receive status is reported as Alignment
Error.
Frames Tx with one Collision. A count of the frames that were involved
in a single collision and were subsequently transmitted successfully. This
counter is incremented when the result of a transmission is reported as
Transmit OK and the attempt value is 2.
Frames Tx with more than one Collision. A count of the frames that
were involved in more than one collision and were subsequently
transmitted successfully. This counter is incremented when the transmit
status is reported as Transmit OK and the value of the attempts variable is
greater than 2 and less than or equal to the attempt limit.
