Figure 4-8. FDDI MAC Chart Window
The MAC Chart provides the following information about the selected MAC
entity in both numeric and graphical form:
Frame Count
Displays the total number of frames received by the selected MAC.
Error Count
Displays a count of error frames that were detected by the selected MAC that had
not been detected previously by another station. An error frame is any received
frame that does not meet frame validity criteria: each frame must have a starting
delimiter, a frame control field, zero or more additional data symbols, and an
ending delimiter. The detecting station sets the Frame Status Error Indicator, and
repeats the packet. Subsequent receiving stations do not count the frame as an
error frame.
