84 CHAPTER 4: PORT COMMANDS
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.
