Gator Total Repeater Statistics 3-3
LocalTalk and GatorStar Statistics
Random CTS Errors The total number of times the LocalTalk interface
received a lapCTS packet that was not solicited by a
lapRTS packet.
FCS Errors The total number of times the LocalTalk interface
received a packet with an FCS (Frame Check Sequence)
error. When a packet is transmitted, the MAC layer of the
transmitting device computes an FCS value based on the
contents of the packet, and appends that value to the
packet. The receiving station performs the same
computation. If the FCS values differ, the packet is
assumed to be corrupted.
Gator Total Repeater Statistics
The Gator Total Repeater Statistics window displays the total number of repeater
statistics and error breakdowns at the device level for the GatorStar GX-M only.
The pie chart to the right of the statistics text boxes allows you to graphically view
the statistics.
By using the Total and Delta option buttons, you can change the time period
during which statistical data is collected. Total gathers data from the device and
updates it at each subsequent polling interval. After the completion of the current
polling cycle plus one complete polling cycle, the window will display the sum of
statistics processed since the device was last restarted. Delta gathers data during
the last polling interval (after the completion of the current polling cycle plus two
more polling cycles). These counts are refreshed after each polling cycle.
