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.
