Statistics

Fragments

Indicates the number of packets processed by the

 

network segment that were undersized (less than 64

 

bytes in length; a runt packet) and had either a

 

non-integral number of bytes (alignment error) or a bad

 

frame check sequence (CRC error).

Jabbers

Indicates the number of packets processed by the

 

network segment that were oversized (greater than 1518

 

bytes; a giant packet) and had either a non-integral

 

number of bytes (alignment error) or a bad frame check

 

sequence (CRC error).

Collisions

Indicates the total number of receive (those the device

 

detects while receiving a transmission) and transmit

 

(those the device detects while transmitting) collisions

 

detected on the network segment.

Undersized

Indicates the number of packets processed by the

 

network segment that contained fewer than 64 bytes

 

(runt packets) but were otherwise well-formed.

Oversized

Indicates the number of packets processed by the

 

network segment that contained more than 1518 bytes

 

(giant packets) but were otherwise well-formed.

In their default state, the percentages displayed to the right of the numerical values for these fields indicate what percentage of total packets transmitted on the network segment were of the noted type. If you select the % of Tot. Errors option by clicking the mouse button in the check box, the percentages will indicate what percentage of problem, or error, packets transmitted on the network segment were of the noted type; these percentages will add up to 100. (The % of Tot. Errors option is active if there is an X in the check box.) The pie chart in the center of the window provides a graphical view of the selected percentage breakdown; colors in the pie chart correspond to colors in the percentage display boxes. Values listed to the right of the pie chart indicate peak delta values recorded since the statistics screen was launched, and the date and time they occurred.

Frame Size (Bytes) Packets

The Frame Size (Bytes) Packets fields indicate the number of packets (including error packets) processed by the network segment that were of the noted length, excluding framing bits but including frame check sequence bits. Packet sizes counted are:

•64

•65-127

•128-255

•256-511

•512-1023

•1024-1518
