SMT/MAC Configuration

Viewing the FDDI MAC Chart

To view the FDDI MAC Chart window, highlight an entry in the MAC
Configuration scroll list and click

. The FDDI MAC Chart window,

Figure 4-8

, will appear.

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.
