Configuring Event Logging
Overview
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
The system allows you 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.
The System 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.

Logging Levels
Command Attributes
• System Log Status: Enables/disables the logging of debug or error messages to the logging process.
• Flash Level: Limits log messages saved to the switch’s permanent flash memory for all levels up to
the specified level. For example, if level 3 is specified, all messages from level 0 to
level 3 will be logged to flash.
Range: 0-7
Default: 3
See the Logging Levels table on page 39for details.
• RAM Level: Limits log messages saved to the switch’s temporary RAM memory for all levels up to
the specified level. For example, if level 7 is specified, all messages from level 0 to
level 7 will be logged to RAM. (Range: 0-7, Default: 6)
Note: The Flash Level must be equal to or less than the RAM Level.
