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).
