The unit can be rebooted using the option available on the Diagnostic tab
Interface Mode - Allows the Host and network interfaces to be switched Up/Down.
Laser Mode - Allows the Host and network Lasers to be individually switched On/Off.
Pause - The Pause option is a special Ethernet function that provides flow control between
Ethernet devices. If the switch on the public network is told to enable Pause, then a rule has to
be configured on the encryption unit to let the Pause frames pass through unencrypted to the
switch on the local side. A typical rule is:
Plain public 01:80:c2:00:00:01.
This Multicast address corresponds to address reserved in IEEE 802.3 for the Pause
functionality.
Note: The Pause tick box is not displayed for the 10Gig Ethernet unit.
Pause frames can still be used with the 10Gig Ethernet unit but this will not be
auto negotiated and would still require the configuration of a rule to pass
pause frames in the plain.
Auto Negotiation- allows the unit to automatically negotiate connection without intervention
from the user.
Note: The Datacryptor 1 Gig Ethernet only supports I000 Mbps full duplex, and the
10 Gig Ethernet unit only supports I0,000 Mbps full duplex. The 100 Mb unit
supports a selection of one 10 Mbps or 100 Mbps. Anything else will cause the
auto negotiation (if selected) to fail and report Link Down on the General tab
interface status box.
The Auto Negotiation tick box is not displayed for the 10Gig Ethernet unit
since the 10Gig Ethernet unit does not support auto negotiation.
Frame Checksum. If the FCS box is checked then the checksum is stripped off the incoming
frame and added again for outgoing frames. When the FCS box is not checked the FCS is
treated like normal data will be and encrypted and decrypted like data on the public interface.
The FPV imposes the following defaults when switching modes. When switching from Bulk to
Tunneling the Network FCS is checked. When switching from Tunneling to Bulk, the Network
FCS is unchecked. It is advised that the user accepts these default settings.
Status- Shows the current status of the Host and network interfaces.
