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
(3500, 3900 and
9000)
Number of frames received by this port that are not an integral
number of octets in length and do not pass the FCS check.
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
(3500, 3900 and
9000)
Number of frames that were discarded because the carrier
sense condition was lost while transmitting a frame from this
port.
excessCollision
(3500, 3900 and
9000)
Number of frames that have been dropped because they
experienced 15 consecutive collisions when sent from this port.
This value is incremented by 1 each time that a frame
experiences 15 consecutive collisions.
excessDeferrals
(3500 and 9000
Layer 3)
Number of frames that were not transmitted on this port
because the maximum allowed deferral time was exceeded.
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
(3900, 9000
Layer 2, 9300 and
9400)
Number of frames received by this port that were shorter than
64 bytes and had CRC or alignment errors.
jabbers
(3900, 9000
Layer 2, 9300 and
9400)
Number of frames received by this port that were longer than
1518 bytes and had CRC or alignment errors.
lateCollisions
(3500, 3900 and
9000)
Number of times that a collision was detected on this port later
than 512 bit-times into the transmission of a frame.
lengthErrs
(3500 and 9000
Layer 3)
Number of frames received by this port that are longer than
1518 bytes or shorter than 64 bytes.
