Number of frames transmitted from the
port, grouped by size.
CRC Error Number of frames with a cyclic
redundancy check (CRC) error but with
the proper length (64-1518 bytes)
received on the port.
Jabber Number of occurrences of corrupted data
or useless signals appearing on the port.
No. of Rx Errors Total number of frames received on the
port containing errors.
Undersize Frames Number of frames that were less than the
minimum length specified by IEEE 802.3
(64 bytes including the CRC) received on
the port.
Oversize Frames Number of frames exceeding the
maximum specified by IEEE 802.3 (1518
bytes including the CRC) received on the
port.
Fragments Number of undersized frames, frames
with alignment errors, and frames with
frame check sequence (FCS) errors (CRC
errors) received on the port.
TX Collisions Number of transmit collisions.
