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 6 to be logged to RAM.

Command Attributes

•System Log Status – Enables/disables the logging of debug or error messages to the logging process. (Default: Enabled)

•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)

		Table 3-3 Logging Levels
Level	Severity Name		Description
7	Debug		Debugging messages
6	Informational		Informational messages only
5	Notice		Normal but significant condition, such as cold start
4	Warning		Warning conditions (e.g., return false, unexpected return)
3	Error		Error conditions (e.g., invalid input, default used)
2	Critical		Critical conditions (e.g., memory allocation, or free memory
			error - resource exhausted)
1	Alert		Immediate action needed
0	Emergency		System unusable

*There are only Level 2, 5 and 6 error messages for the current firmware release.

•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.
