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