Total Errors (Read-only)
Displays the total number of errors.
Collisions (Read-only)
Displays the total number of collisions that were detected.
OOW Collisions (Read-only)
Displays the number of Out Of Window (OOW) collision errors detected.
These collisions can be caused by a station on the network violating
Carrier Sense and transmitting at will, a cable failure occurring during the
transmission of a frame, or a network propagation delay greater than
51.2 µs.
CRC Errors (Read-only)
Displays the number of frames with bad Cyclic Redundancy Checks
(CRC) received from the network. The CRC is a 4-byte field in the data
frame that ensures that the data that is received is the same as the data that
was originally sent.
Alignment Errors (Read-only)
Displays the number of alignment errors detected. Alignment errors occur
when the total number of bits in a frame are not divisible by eight due to
missing bits in the bytes contained in the frame.
Undersize Packets (Read-only)
Displays the number of frames received with a valid CRC and whose size
was less than the minimum Ethernet frame size of 64 bytes (not including
the preamble).
Oversize Packets (Read-only)
Displays the number of frames received with a valid CRC and whose size
exceeded 1518 data bytes (not including preamble).
