Configuring Event Logging
– 408 –
◆ Loopback Detection (LBD) – Detects general loopback conditions caused by
hardware problems or faulty protocol settings.
◆ Smart Pair Configuration – Detects general loopback conditions caused by
hardware problems or faulty protocol settings.
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.
Parameters
These parameters are displayed:
◆ Status – Enables/disables the logging of debug or error messages to the
logging process. (Default: Enabled)
◆ History 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 26: Logging Levels
Level Severity Name Description
7 Debugging 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)
* There are only Level 2, 5 and 6 error messages for the current firmware release.
