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 LOG
CONFIGURATION
Use the Administration > Log > System (Configure Global) page to enable
or disable event logging, and 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 System Logs page allows you to configure and limit system messages
that are logged to flash or RAM memory. The default is for event levels 0 to
3 to be logged to flash and levels 0 to 7 to be logged to RAM.
