Description: Each entry contains the number of Ethernet interface of the device, which will be the index with which the table is crossed, and a set of variables which inform about the number of frames received with length greater than the maximum, number of frames received with CRC error, number of frames received with alignment error, number of FIFO overruns, number of reception errors nondue to excessive collisions or carrier detection, number of lost packets because of the local buffer is full, number of times a transmission has been postponed because of detecting activity in the line, number of frames which have undergone a collision before being transmitted successfully, number of frames which have undergone multiple collisions before being transmitted successfully, total number of collisions, number of frames whose transmission failed because they underwent 16 or more successive collisions, number of errors by FIFO underruns, number of times that a frame collides because carrier detector is disabled, number of SQE test errors, number of frames which undergo a collision when 512 bits have been transmitted already at least, number of transmission errors that are not delayed, excessive collisions or of carrier detection, and finally a variable that controls the erasure of the statistics corresponding to the interface that the index indicates.
