Excessive Bad Entries
If the firmware detects excessive errors in the Flash Event Log (errors exceeding
75 percent), the Flash Event Log is cleared (discarded of all entries) and an event
entry is displayed in the Event Log screen.
Figure 3-23 shows an example of the
Event Log entry for this type of event.

Write Threshold
To extend the lifetime of flash memory for the event log, a write limit threshold
is set for each event that is entered into the event log. The write limit threshold is
20 entries for each event. If any event exceeds the write limit threshold, an event
entry is displayed in the Event Log screen.
Figure 3-24 shows an example of the
Event Log entry for this type of event.
Figure 3-24. Event Log entry exceeding write threshold example
The write limit threshold is reset when either of the following occurs:
• The BayStack 350T switch is reset.
• The firmware determines compression is required for the maintenance of the
Event Log.
Entry Number: 4 sysUpTime: 00:20:53 Reset Count: 2
Excessive bad entries in log, Event Log cleared.
Entry Number: 3 sysUpTime: 00:38:53 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.
