Configuring Event Logging
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.
