received
The total number of correct octets received
Alignment Errors A counter of frames received that are not an integral
number of octets in length (RFC 1643).
FCS Error A counter of frames received that do not pass the FCS
check (RFC 1643).
Frames transmitted to the network
Correct Frames The total number of frames successfully transmitted
Correct Octets The total number of octets successfully transmitted
Single Collision Valid only in half duplex mode
(RFC 1643)
A counter of successfully transmitted frames for which
transmission is inhibited by exactly one collision.
Multiple Collision Valid only in half duplex mode
(RFC 1643)
A counter of successfully transmitted frames for which
transmission is inhibited by more than one collision.
Deferred
Transmission
Valid only in half duplex mode
(RFC 1643)
A counter of frames for which the first transmission
attempt is delayed because the medium is busy.
Late Collision Valid only in half duplex mode
(RFC 1643)
The number of times that a collision is detected on a
particular interface later than 512 bit-times into the
transmission of a packet.
Carrier Sense Error Valid only in half duplex mode
(RFC 1643)
The number of times that the carrier sense condition
was lost or never asserted when attempting to transmit
