Chapter 2: AT-2931SX Broadcom Advanced Control Suite (BACS) Applications

counter is incremented when the result of a transmission is reported as Transmit OK and the attempt value is 2.

ˆFrames 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.

ˆFrames 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 AT-2931SX adapter.

ˆNumber of Interrupts generated by this adapter. The number of interrupts generated by the device.

ˆNumber of Interrupts avoided by this adapter. The number of interrupts avoided by the device.

ˆTx Max Coalesce Frames Threshold hit. The number of times the Send Max Coalesce Frames Threshold was hit.

ˆRx Max Coalesce Frames Threshold hit. The number of times the Receive Max Coalesce Frames Threshold was hit.

ˆDMA write Queue was full. The number of times the DMA write queue was full.

ˆDMA write High Priority Queue was full. The number of times the DMA write high priority queue was full.

ˆDMA Read Queue was full. The number of times the DMA read queue was full.

ˆDMA Read High Priority Queue was full. The number of times the DMA read high priority queue was full.

ˆSend Data Completion FTQ was full. The number of times the send data completion FTQ (flow through queue) was full.

ˆNIC ran out of the Recv Buffer. The number of times the network adapter ran out of the Recv Buffer descriptors.

ˆFrames size less than 64-byte with bad FCS. The number of frames with a size less than 64 bytes with bad FCS.

ˆMAC Rx w/ Pause Command and Length = 0. MAC control frames with the pause command and a length equal to 0.
