Sent packets are differentiated in terms of:
Number of packets
Number of Unicast packets (packets to one receiver)
Number of non-Unicast packets (packets to multiple receivers)
Received packets are differentiated in terms of:
Number of all packets
Total number of bytes received
Total number of fragments received
The CRC errors column provides information about the number of faulty received data packets. The
cyclical redundancy test, CRC (Cyclic Redundancy Check), specifies a test value using the transferred
data. This value is sent together with the data and evaluated by the receiver. Fault packets are
detected and discarded in this way.
The total number of all collisions and the late collisions are displayed in the collisions column.
The packets up to bytes column provides information about the number of packets in diverse sizes.
In this case, the number of packets received up to 64, 127, 255, 511, 1023, or 1518 bytes in size is
recorded.
Update and reset the values
In the status bar arranged above the table, the table can be updated by pressing a button. Using a
second button, the option is available to reset the counters of all ports and start a new evaluation in
this way. The time at which the evaluation was started is displayed in the status bar as the last reset.
Sort and hide the entries
The port statistics offer valuable information about the network diagnosis. In order to simplify the
diagnosis, the option is available to limit the display to the important columns.
