Statistics

To open the board-level Performance Graph window:

1.Click on the appropriate Board number to display the board menu.

2.Drag down to Performance Graph... and release. The board-level Performance Graph window will appear.

To access the port-level Performance Graph window:

1.Click on the appropriate Port to display the port menu.

2.Drag down to Performance Graph... and release. The port-level Performance Graph window will appear.

The Board and Port Performance Graph windows are the same as the Performance Graph window displayed in Figure 3-6, except that they display statistics applicable to the selected board or port. Each Performance Graph window allows you to graph the following statistical variables:

Total Errors
Total Errors	The total number of errors of any kind processed
	by the device, board, or port.
Collisions	The total number of collisions detected by the
	device, board, or port.
CRC Errors	The total number of packets with CRC (Cyclical
	Redundancy Check) detected by the device,
	board, or port.
Runt Packets	The number of runt packets detected by the
	device, board, or port. A runt frame is one that is
	less than the minimum Ethernet frame size of 64
	bytes.
Giant Packets	The number of giant packets detected by the
	device, board, or port. A giant frame exceeds the
	maximum Ethernet frame size of 1518 bytes
	(excluding the preamble).
Algn. Errors	The number of misaligned packets detected by
	the device, board, or port. Misaligned packets
	are those which contain a non-integral number
	of bytes (that is, any unit of bits less than a byte);
	they can result from a MAC layer packet
	formation problem, or from a cabling problem
	that is corrupting or losing data.
OOW Collns.	The number of collisions out of the standard
	collision window (51.2 µs) detected by the
	device, board, or port. There are two conditions
	which can cause this type of error to occur: either
	the network’s physical length exceeds IEEE 802.3
	specifications, or a node on the net is
