Table 2: Key Controls for Monitor Port Counters Display

Key	Effect on Monitor Display
Spacebar	Advances to the next statistic type.
Esc	Exits the monitor. WSS Software stops displaying the statistics
	and displays a new command prompt.
c	Clears the statistics counters for the currently displayed statistics
	type. The counters begin incrementing again.

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 circum- stances, 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):

WSS# monitor port counters

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