CRC/Alignment | Indicates the number of packets processed by the |
| network segment that had a |
| bytes (alignment error) or a bad frame check sequence |
| (Cyclic Redundancy Check, or CRC error). |
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 |
| |
| 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 |
| 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 |
Oversized | Indicates the number of packets processed by the |
| network segment that contained more than 1518 bytes |
| (giant packets) but were otherwise |
In their default state, the percentages displayed to the right of the numerical values for these Þelds 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.
