Payload Rate This field displays the upstream/downstream payload rate.
SNR Margin This field displays the upstream/downstream SNR margin.
Interleave Delay This field displays the upstream/downstream interleave delay.
Transmit Power This field displays the upstream/downstream transmission power of the line.
Attenuation This field displays the upstream/downstream attenuation.
CRC Error This field displays the number of CRC (Cyclical Redundancy Check) error
packet.
RS Correct This field displays the number of Reed-Solomon (RS) correct packets.
RS Uncorrect This field displays the number of Reed-Solomon (RS) uncorrect packets.
ES This displays port endpoint errored seconds (ESs).
SES This displays port endpoint severely errored seconds (SESs).
Tx Packet
Tx Packets This field displays the number of packets transmitted.
Multicast This field shows the number of good multicast packets transmitted.
Broadcast This field shows the number of good broadcast packets transmitted.
Pause This field shows the number of 802.3x Pause frames transmitted.
Rx Packet
Rx Packets This field displays the number of packets received.
Multicast This field shows the number of good multicast packets received.
Broadcast This field shows the number of good broadcast packets received.
Pause This field shows the number of 802.3x Pause frames received.
Control This field shows the number of control received (including those with CRC error)
but it does not include the 802.3x Pause frames.
Tx Collision
Single This field shows the number of packets with 1 collision detected.
Multiple This field shows the number of packets with 2 to 15 collisions detected.
Excessive This field shows the number of packets with in excess of 15 collisions detected.
Late A late collision is counted when a device detects a collision after it has sent the
512th bit of its frame. This field shows the number of times such a collision is
detected.
Error Packet
Rx CRC This field shows the number of frames with CRC (Cyclic Redundant Check)
error(s).
Length This field shows the number of frames with a length that was out of range.
Runt This field shows the number of frames received that were too short (shorter than
64 octets), including the ones with CRC errors.
Distribution
64 This field shows the number of packets (including bad packets) transmitted that
were 64 octets in length.
65-127 This field shows the number of packets (including bad packets) transmitted that
were between 65 and 127 octets in length.
