■
Broadcast Frames Rx—Count of frames that are successfully received and are directed
to the broadcast group address. This does not include frames received with frame-
too-long, FCS, length or alignment errors, or frames lost due to internal MAC
sublayer error. This counter is incremented as indicated by the receiveOK status, and
the value in the Destination field.
IEEE 802.3
Interface components of the Statistics/IEEE 802.3 window are described below:
■
Frames Rx with Alignment Error—Count of frames that are not an integral number of
octets in length and do not pass the FCS check. This counter is incremented when the
ReceiveStatus is reported as alignmentError.
■
Frames Tx with one Collision—Count of frames that are involved in a single collision,
and are subsequently transmitted successfully. This counter is incremented when the
result of a transmission is reported as transmitOK and the attempt value is 2.
■
Frames Tx with more than one Collision—Count of frames that are involved in more
than one collision, and are subsequently transmitted successfully. This counter is
incremented when the TransmitStatus is reported as transmitOK and the value of
the attempts variable is greater than 2 and less than (or equal to) attemptLimit.
■
Frames Tx after Deferral—Count of frames whose transmission was delayed on its
first attempt because the medium was busy. Frames involved in any collision are
not counted.
Custom Tab
Descriptions of interface components of 3Com’s Management Programs/Custom tab
window are described below.
■
Number of Interrupts generated by this adapter—Number of interrupts generated
by NIC.
■
Number of Interrupts avoided by this adapter—Number of interrupts avoided by NIC.

Rx. Max Coalesce Frames Threshold hit—Number of times Recv Max Coalesce Frames
Threshold hit.
■
DMA write Queue was full—Number of times DMA write queue was full.
■
DMA write High Priority Queue was full—Number of times DMA write high priority
queue was full.
■
DMA Read Queue was full—Number of times DMA read queue was full.
■
DMA Read High Priority Queue was full—Number of times DMA read high priority
queue was full.
■
Send Data Completion FTQ was full—Number of times send data completion
FTQ(Flow Through Queue) was full.
■
NIC ran out of the Recv. Buffer—Number of times NIC ran out of the Recv Buffer
Descriptors.
■
Frames size less than 64-byte with bad FCS—Frames size less than 64-byte with bad
FCS(Frame Checksum).
■
MAC Rx. w/ Pause Command and Length = 0—MAC control frames with pause
command and length equal to zero.
■
MAC Rx. w/ Pause Command and Length greater than 0—MAC control frames with
pause command and length greater than zero.
■
MAC Rx. w/ no Pause Command—MAC control frames with no pause command.
■
MAC Sent Xon—MAC Transmit with Xon was on.
■
MAC Sent Xoff—MAC Transmit with Xon was off.
