Functional Description
14.3.2.20.3.4 Rx + Tx 256–511 Octet Frames (Offset = 74h)
The total number of frames of size 256 to 511 bytes received and transmitted on the port. Such a frame is
defined to be:
•
Any data or MAC control frame which was destined for any unicast, broadcast or multicast address
•
Did not experience late collisions, excessive collisions, or carrier sense error
•
Was 256 to 511 bytes long
CRC errors, code/align errors, underruns and overruns do not affect the recording of frames in this
statistic.
14.3.2.20.3.5 Rx + Tx 512–1023 Octet Frames (Offset = 78h)
The total number of frames of size 512 to 1023 bytes received and transmitted on the port. Such a frame
is defined to be:
•
Any data or MAC control frame which was destined for any unicast, broadcast or multicast address
•
Did not experience late collisions, excessive collisions, or carrier sense error
•
Was 512 to 1023 bytes long
CRC errors, code/align errors, underruns and overruns do not affect the recording of frames in this
statistic.
14.3.2.20.3.6 Rx + Tx 1024_Up Octet Frames (Offset = 7Ch)
The total number of frames of size 1024 to rx_maxlen bytes for receive or 1024 up for transmit on the
port. Such a frame is defined to be:
•
Any data or MAC control frame which was destined for any unicast, broadcast or multicast address
•
Did not experience late collisions, excessive collisions, or carrier sense error
•
Was 1024 to rx_maxlen bytes long on receive, or any size on transmit
CRC errors, code/align errors, underruns and overruns do not affect the recording of frames in this
statistic.
