7.4. Statistics
The statistics window opens in a separate window and displays a table of the number of
Ethernet frames counted by the Ethernet task. These are classified according to whether
they were transmitted, received for the local IP address or received as broadcast frames and
divided into IP protocol types. Since the values can continue to change, the user can update
the window by clicking on the “Refresh” button. It is also possible to reset the counters if
desired by clicking on “Reset frame stats”.
The contents of the ARP cache is also displayed and can be cleared by clicking on “Delete
ARP entries”. These are equivalent to the DOS commands arp –a to display the local ARP
cache and arp –d to delete it. Notice that when the ARP cache is deleted via the web page
there will always remain one entry, this being the PC which commanded the deletion of the
ARP table and updated the table. Due to the network activity it will always immediately be re-
entered…
