Using the BayStack 350 10/100 Autosense Switch
Excessive Bad Entries
If the firmware detects excessive errors in the event log’s flash memory (errors exceeding 75 percent of the memory buffer), the event log is cleared (that is, all entries are discarded) and 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.
Entry Number: 4 | sysUpTime: 00:20:53 | Reset Count: 2 |
Excessive bad entries in log, Event Log cleared.

Write Threshold
To extend the lifetime of the event log’s flash memory, a write threshold is set for each event entered in the event log’s 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 3-25 shows an example of the event log entry for this type of event.
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. |
Figure 3-25. Sample event log event exceeding the write threshold
The write threshold is reset when either of the following occurs:
•The BayStack 350 switch is reset.
•The firmware determines that compression is required for maintenance of the event log’s flash memory.
