Using the BayStack 450 10/100/1000 Series Switch
3-130 309978-D Rev 01
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 3-52 shows an example of the event log entry for this type of event.
Figure 3-52. Sample Event Log Entry Exceeding the Write Threshold
The write threshold is reset when either of the following occurs:
• The BayStack 450 switch is reset.
• The firmware determines that compression is required for maintenance of the
event log’s flash memory.
Flash Update
Figure 3-53 shows an example of the event log entry for this type of event.

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.
