Configuring Event Logging
The switch allows you to control the logging of error messages, including the type of
events that are recorded in switch memory, logging to a remote System Log (syslog)
server, and displays a list of recent event messages.
System Logs
The system can be configured to send debug and error messages to a logging
process. This logging process controls the type of error messages that are stored in
switch memory or sent to a remote syslog server.
System log messages are categorized by severity into eight levels, as detailed in the
following table.
The switch allows you to specify which levels are logged to RAM or flash memory.
Severe error messages that are logged to flash memory are permanently stored in
the switch to assist in troubleshooting network problems. Up to 4096 log entries can
be stored in the flash memory, with the oldest entries being overwritten first when the
available log memory (256 kilobytes) has been exceeded.
The Logs page allows you to scroll through the logged system and event messages.
The switch can store up to 2048 log entries in temporary random access memory
(RAM; i.e., memory flushed on power reset) and up to 4096 entries in permanent
flash memory.
