SD Delete File after Sending
Normally, the files are kept on SD card and are not deleted by the
system, except when the maximum number of files is reached in
which case the oldest files are overwritten automatically.
It is an option to delete files after the content was sent to a Tunnel
server. A certain risk is taken then, because data cannot be recovered
anymore after deletion.
SD Files in PCAP Format
Enabling this option sets the V-Tap unit in a completely different
mode. The format of the stored packets in the files on the SD card
changes to the PCAP format. The files on the card are given the
extension .CAP and are directly readable by PC tools like Wireshark.
The Tunnel function itself is disabled, but packets still must pass the
Tunnel filters before they are stored.
This mode can be used for network debugging or network tracing.
SD Interface Speed in MHz
This value must be changed only when there are problems with an
SD card. The default is good for most of the cards on the market.
Valid speeds to enter: 1 till 12 , 15 , 17 , 20 , 24 , 30 , 40 and 60.
