Fields in the Ethernet Detail Display
Field Description
actualFlowControl Actual flow control setting. When autonegotiation is
completed, the value is the autonegotiated setting. When
autonegotiation is disabled, the value is the user-selected flow
control value.
actualPortMode Actual operating port mode. When autonegotiation is
completed, the value shown is the autonegotiated setting.
When autonegotiation is disabled, the value is the port mode.
alignmentErrs Number of frames received by this port that are not an integral
(3500, 3900 and number of octets in length and do not pass the FCS check.
9000)
autoNegMode Autonegotiation mode configured for port. Possible values are
enable or disable.
autoNegState Current negotiation state. Possible values are disabled,
configuring, completed, and failed.
carrierSenseErr Number of frames that were discarded because the carrier
(3500, 3900 and sense condition was lost while transmitting a frame from this
9000) port.
excessCollision Number of frames that have been dropped because they
(3500, 3900 and experienced 15 consecutive collisions when sent from this port.
9000) This value is incremented by 1 each time that a frame
experiences 15 consecutive collisions.
excessDeferrals Number of frames that were not transmitted on this port
(3500 and 9000 because the maximum allowed deferral time was exceeded.
Layer 3)
fcsErrs Number of frames received by this port that are an integral
number of octets in length but do not pass the frame check
sequence (FCS) test.
fragments Number of frames received by this port that were shorter than
(3900, 9000 64 bytes and had CRC or alignment errors.
Layer 2, 9300 and
9400)
jabbers Number of frames received by this port that were longer than
(3900, 9000 1518 bytes and had CRC or alignment errors.
Layer 2, 9300 and
9400)
lateCollisions Number of times that a collision was detected on this port later
(3500, 3900 and than 512 bit-times into the transmission of a frame.
9000)
lengthErrs Number of frames received by this port that are longer than
(3500 and 9000 1518 bytes or shorter than 64 bytes.
