For error reporting, the cyclic redundancy check (CRC) errors include 
misalignment errors. Jumbo packets with valid CRCs are not counted. A 
short packet can be reported as a short packet, a CRC error, or an 
overrun. In some circumstances, the transmitted octets counter might 
increment a small amount for a port with nothing attached.

Examples — The following command starts the port statistics monitor 
beginning with octet statistics (the default):

WX4400# monitor port counters

As soon as you press Enter, MSS clears the window and displays statistics 
at the top of the window.

example, packet statistics are displayed next:
