Excessive Bad Entries
If the firmware detects excessive bad entries in the event log’s flash memory
(errors exceeding 75 percent of the memory buffer), the event log is cleared (all
entries are discarded) and an event entry is displayed in the Event Log screen.
Figure 3-37
shows an example of the event log entry for this type of event.

Write Threshold
To extend the lifetime of the event log’s flash memory, a write threshold is set for
each event entered in flash memory. The write threshold is 20 entries for each
event. If any event exceeds the write threshold, an event entry is displayed in the
Event Log screen.
Figure 3-38
shows an example of the event log entry for this type of event.
Figure 3-38. Sample Event Log Entry Exceeding the Write Threshold
Entry Number: 4 sysUpTime: 00:20:53 Reset Count: 2
Excessive bad entries in log, Event Log cleared.
Entry Number: 3 sysUpTime: 02:29:44 Reset Count: 2
The last event exceeded the write threshold. Further write attempts
by this event are blocked. The write threshold will be cleared when
the switch is reset or when the Event Log is compressed.
