Chapter 2: Broadcom Advanced Control Suite 2 (BACS 2) Applications

This does not include frames received with frame-too-long, FCS,

length errors, alignment errors, or frames lost due to internal MAC

sublayer errors. This counter is incremented as indicated by the

Receive OK status.

 Broadcast Frames Rx. A count of frames that are successfully

received and are directed to a broadcast group address. This count

does not include frames received with frame-too-long, FCS, length

errors, alignment errors, or frames lost due to internal MAC sublayer

errors. This counter is incremented as indicated by the Receive OK

status.

IEEE 802.3 Statistics

Definitions of the IEEE 802.3 statistics parameters are provided below.

 Frames Rx with Alignment Error. A 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 receive status is reported as

Alignment Error.

 Frames Tx with one Collision. A 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

Transmit OK and the attempt value is 2.

 Frames Tx with more than one Collision. A count of frames that are

involved in more than one collision and are 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 or equal to the attempt limit.

 Frames Tx after Deferral. A count of frames whose transmission was

delayed on the first attempt because the medium was busy. The

frames involved in any collision are not counted.

Custom Statistics

Definitions of the custom statistics parameters are provided below.

Note

Custom statistics are available only for an enabled adapter.

 Number of Interrupts generated by this adapter. The number of

interrupts generated by the device.

 Number of Interrupts avoided by this adapter. The number of

interrupts avoided by the device.

 Tx Max Coalesce Frames Threshold hit. The number of times the

Send Max Coalesce Frames Threshold was hit.
