Excessive Collisions A count of frames for which transmission on a particular
interface fails due to excessive collisions. This counter does
not increment when the interface is operating in full-duplex
mode.
Single Collision Frames The number of successfully transmitted frames for which
transmission is inhibited by exactly one collision.
Internal MAC Transmit
Errors
A count of frames for which transmission on a particular
interface fails due to an internal MAC sublayer transmit error.
Multiple Collision Frames A count of successfully transmitted frames for which
transmission is inhibited by more than one collision.
Carrier Sense Errors The number of times that the carrier sense condition was lost
or never asserted when attempting to transmit a frame.
SQE Test Errors A count of times that the SQE TEST ERROR message is
generated by the PLS sublayer for a particular interface.
Frames Too Long A count of frames received on a particular interface that
exceed the maximum permitted frame size.
Deferred Transmissions A count of frames for which the first transmission attempt on
a particular interface is delayed because the medium was busy.
Internal MAC Receive
Errors
A count of frames for which reception on a particular
interface fails due to an internal MAC sublayer receive error.
RMON Statistics
Drop Events The total number of events in which packets were dropped
due to lack of resources.
Jabbers The total number of frames received that were longer than
1518 octets (excluding framing bits, but including FCS
octets), and had either an FCS or alignment error.
Received Bytes Total number of bytes of data received on the network. This
statistic can be used as a reasonable indication of Ethernet
utilization.
Collisions The best estimate of the total number of collisions on this
Ethernet segment.
