FLASH Log

The FLASH log is a log that is stored in persistent storage, which means that the log 
messages are retained across a switch reboot. 

Either the system startup log or the system operation log stores a message received by the 
log subsystem that meets the storage criteria, but not both. On system startup, if the startup 
log is configured, it stores messages up to its limit. The operation log, if configured, then 
begins to store the messages.

Use the FLASH Log screen to enable or disable persistent logging and to set the severity 
filter.

From the Severity Filter field, specify the type of log messages to record. 

A log records messages equal to or above a configured severity threshold. For example, 
if you select Error, the logged messages include Error, Critical, Alert, and Emergency. The 
default severity level is Alert (1). The severity can be one of the following levels:

 (0). The highest warning level. If the device is down or not functioning 

properly, an emergency log is saved to the device. 

 (1). The second-highest warning level. An alert log is saved if there is a serious 

device malfunction, such as all device features being down. Action must be taken 
immediately.

 (2). The third-highest warning level. A critical log is saved if a critical device 

malfunction occurs, for example, two device ports are not functioning, while the rest of 
the device ports remain functional. 

 (3). A device error has occurred, such as if a port is offline. 

 (4). The lowest level of a device warning.
