Port Statistics
Use the Port Statistics menu to display Etherlike or RMON statistics for any port on the switch. Select the required port. The statistics displayed are indicated in the following figure and table.

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 |
Frames* | transmission 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 |
| |
Excessive | The number of frames for which transmission failed due to |
Collisions* | excessive collisions. |
Internal Mac | The number of frames for which transmission failed due to an |
Transmit Errors* | internal MAC sublayer transmit error. |
Carrier Sense | The number of times that the carrier sense condition was lost or |
Errors* | never asserted when attempting to transmit a frame. |
Frames Too Long | The number of frames received that exceed the maximum |
| permitted frame size. |
Internal Mac | The number of frames for which reception failed due to an |
Receive Errors* | internal MAC sublayer receive error. |
*The reported values will always be zero because these statistics are not supported by the internal chip set.
