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.
Received Frames The total number of frames (bad, broadcast and
multicast) received.
Broadcast Frames The total number of good frames received that were
directed to the broadcast address. Note that this does
not include multicast packets.
