ETHERNET Statistics View

Note

For analyzing this view, basic ETHERNET knowledge is required.

ETHERNET statistics provides information about transmit and receive traffic. The load and the quality of communication can be observed. Problems due to too much network load or internal resource problems will be shown here in terms of error counters.

Parameter	Meaning
Frames transmitted successfully	Number of frames transmitted successfully
Frames with single collision	Number of frames with single collision detected
Frames with multiple collisions	Number of frames with multiple collisions detected
Late collisions	Number of frames with collision detected later than 512 bit times
Link down during transmission	Number of frames transmitted while link state went down
UTX FIFO underflow	Number of UTX FIFO underflows occurred while transmitting frames
Fatal transmission errors	Number of TPU error codes detected while transmitting frames
Frames received successfully	Number of frames received successfully
Sequence check errors	Number of frames received with valid length but not passing the FCS check
Alignment errors	Number of frames received with not valid length and not passing the FCS check
Frame too long errors	Number of frames received with maximum permitted frame size exceeded
Valid frames with length between 42 and 63 bytes	Number of frames received with length between 42 to 63 bytes and valid checksum
Collision fragments	Number of frames received with length smaller than 64 bytes and invalid checksum
Dropped frames due to low resources	Number of frames received while no resources available to handle the frames
Dropped frames due to URX FIFO overflow	Number of UTX FIFO overflows occurred while receiving frames
Fatal receive errors	Number of RPU error codes detected while receiving frames
