security log administrator can trigger the saving of security logs into the log file manually). After the
contents of the buffer are saved into the security log file successfully, the security log file buffer is cleared
immediately.
The size of the security log file is limited. When the size of the security log file reaches the predefined
maximum value, the system deletes the oldest information and then writes the new information into the
security log file. To avoid security log file loss, you can set the alarm threshold of the security log file
usage. When the alarm threshold is reached, the system outputs the log information to inform the
administrator. In this case, the administrator can log in to the device as the security log administrator, and
then back up the security log file, preventing the loss of important historical data.
By default, the saving of security logs into the security log file is disabled. The parameters, such as the
saving frequency, the maximum size and the alarm threshold of the security log file usage, have their
default settings. To modify these parameters, you need to log in to the device as the system administrator,
and then follow the steps in the following table to configure the related parameters:
