Table 7-1 Description of Fields for Ethernet Port Attributes
Field Description
alignmentErrs Number of frames received by this port that are not an integral
number of octets in length and do not pass the FCS check
carrierSenseErr Number of frames discarded because the carrier sense condition
was lost while attempting to transmit a frame from this port
collisions Number of collisions detected on this port
duplexMode Current duplex mode setting. Possible values are full, half, and not
applicable (n/a). Duplex mode is not applicable on the Switch 2200.
excessCollision Number of frames that could not be transmitted on this port
because the maximum allowed number of collisions was exceeded
excessDeferrals Number of frames that could not be 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 FCS check
lateCollisions Number of times a collision was detected on this port later than 512
bit-times into the transmission of a frame
lengthErrs Number of frames received by this port longer than 1518 bytes or
shorter than 64 bytes
linkStatus Boolean value indicating the current state of the physical link status
for this port (either enabled or disabled)
macAddress The MAC address of this port
noRxBuffers Number of frames discarded because there was no available buffer
space
