The log file feature saves logs from the log file buffer to a log file every 24 hours. You can adjust the
saving interval or manually save logs to the log file. After saving logs into the log file, the system clears
the log file buffer.
The router supports multiple log files. Each log file has a specific capacity. The log files are named as
logfile1.log, logfile2.log, and so on. When the capacity of logfile1.log is reached, the system compresses
logfile1.log as logfile1.log.gz and creates a new log file named logfile2.log. You can download the
compressed log files. The maximum number of log files depends on the device model. When the last log
file is full or the storage device runs out of space, the system deletes the earliest log file and creates a new
one.
