DESCRIPTION
This field displays the upstream/downstream payload rate.
This field displays the upstream/downstream SNR margin.
This field displays the upstream/downstream transmission power of the line.
This field displays the upstream/downstream attenuation.
This field displays the number of CRC (Cyclical Redundancy Check) error
packet.
This field displays the number of Reed-Solomon (RS) correct packets.
This field displays the number of Reed-Solomon (RS) uncorrect packets.
This displays port endpoint errored seconds (ESs).
This displays port endpoint severely errored seconds (SESs).
This field displays the number of packets transmitted.
This field shows the number of good multicast packets transmitted.
This field shows the number of good broadcast packets transmitted.
This field shows the number of 802.3x Pause frames transmitted.
This field displays the number of packets received.
This field shows the number of good multicast packets received.
This field shows the number of good broadcast packets received.
This field shows the number of 802.3x Pause frames received.
This field shows the number of control received (including those with CRC error)
but it does not include the 802.3x Pause frames.
This field shows the number of packets with 1 collision detected.
This field shows the number of packets with 2 to 15 collisions detected.
This field shows the number of packets with in excess of 15 collisions detected.
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.
This field shows the number of frames with CRC (Cyclic Redundant Check)
error(s).
This field shows the number of frames with a length that was out of range.
This field shows the number of frames received that were too short (shorter than
64 octets), including the ones with CRC errors.
This field shows the number of packets (including bad packets) transmitted that
were 64 octets in length.
This field shows the number of packets (including bad packets) transmitted that
were between 65 and 127 octets in length.
