4.3.7 Logs
4.3.7.1 Buffered Log
The log messages the device generates in response to events, faults, errors, and
configuration changes are stored locally on the device in the RAM (cache). This col-
lection of log files is called the RAM log or buffered log. When the buffered log file
reaches the configured maximum size, the oldest message is deleted from the RAM
when a new message is added. If the system restarts, all messages are cleared.
