Parameter | Description |
|
|
|
| |
Alignment Errors | The number of frames received that are not an integral number of | |||||
|
| octets in length and do not pass the FCS check. | ||||
FCS Errors | The number of frames received that are an integral number of | |||||
|
| octets in length but do not pass the FCS check. | ||||
Single Collision | The number of successfully transmitted frames for which | |||||
Frames* | transmission is inhibited by exactly one collision. | |||||
Multiple Collision | A count of successfully transmitted frames for which transmission | |||||
Frames* | is inhibited by more that one collision. |
|
| |||
SQE Test Errors* | A count of times that the SQE TEST ERROR message is | |||||
|
| generated by the PLS sublayer. |
|
| ||
Deferred | A count of frames for which the first transmission attempt on a | |||||
Transmissions* | particular interface is delayed because the medium was busy. | |||||
Late Collisions | The number of times that a collision is detected later than 512 bit- | |||||
|
| times into the transmission of a packet. |
|
| ||
Excessive Collisions* | The number of frames for which transmission failed due to | |||||
|
| excessive collisions. |
|
| ||
Internal Mac | The number of frames for which transmission failed due to an | |||||
Transmit Errors* | internal MAC sublayer transmit error. |
