Carrier Sense Errors
The number of times that the carrier sense signal was lost or missing when trying to transmit a frame on
this interface.
SQE Test Errors
The number of times that the SQE (Signal Quality Error) Test Error message was generated for this
interface. The SQE message tests the collision circuits on an interface.
Frame Too Long Errors
The number of frames received on this interface that exceed the maximum permitted frame size.
Deferred Transmits
The number of frames for which the first transmission attempt on this interface is delayed because the
medium is busy. This number does not include frames involved in collisions.
Single Collisions
The number of successfully transmitted frames on this interface for which transmission is inhibited by
exactly one collision. This number is not included in the Multiple Collisions number.
Multiple Collisions
The number of successfully transmitted frames on this interface for which transmission is inhibited by
more than one collision. This number does not include the Single Collisions number.
Late Collisions
The number of times that a collision is detected on this interface later than 512 bit-times into the
transmission of a packet. 512 bit-times = 51.2 microseconds on a 10-Mbps system.
