Frame Alignment Errors
Displays the number of errors due to misaligned packets.
CRC Errors
Displays the number of packets with bad Cyclical Redundancy Checks
(CRC) that have been received from the network. This error is caused by a
network device interfering with the original size of the packet when it is
transmitted or received.
Giant Packets
Displays the number of packets received whose size exceeded 1518 data
bytes, not including preamble. The originating station or transceiver is
responsible for creating giant packets.
Port Admin. Status
Displays the administrative status of the port. The two possible status
messages are ON or OFF. Status is affected by the Enable/Disable
Board/Port options and by the Port Association option.
Port Seg. Status
Displays the segmentation status of the port. The two possible status
messages are ON or SEG (Segmented). The port is normally ON, but is
segmented if 32 consecutive collisions occur.
