You can do Wireshark captures in the background from the router to an attached USB drive, e.g. write to a USB stick. An active management session from the computer to the device is not required for this.
After recording, the file can be accessed by plugging the USB stick into a computer. Alternatively, the /usb/ directory on the device can be accessed remotely via SCP.
The USB drive must be FAT32 formatted. The device writes to the USB stick until it is full, after which the capture stops.
Enter the file name and all other necessary information using the command line in the table See the Menu Reference Guide for the values.
