VII. Router Diagnostics

Instead of the router sending syslog message to a PC and running a sylog utility on that PC, some DrayTek router models can store syslog to an attached USB Disk. The Vigor2820 series supports this functionality from firmware 3.3.3 and later, check the product specification for your specific model

To enable the router to send syslog message to an attached USB Disk instead of an IP Address, enable the toggle button in the [Syslog] menu. The setting can only be saved if the router has detected that a USB storage device is connected to its USB port. After enabling the setting, the router will create a syslog directory and .log file on the USB disk when it needs to write output to the USB Disk.

The router does not immediately write the output to the USB Disk, it stores in memory first and then, once the log reaches 32KB, it writes the file to the .log file on the USB drive. Once the .log file on the USB drive reaches 1MB, the router will create a new .log with an incremented filename
