Element Description
Enable NTP Authentication Enables or disables authentication with an NTP server. Disabling
authentication does not alter the list of configured servers.
If you enable authentication, the security appliance only communicates
with an NTP server if it uses the correct trusted key in the packets. The
security appliance also uses an authentication key to synchronize with
the NTP server.
NTP Server Table Lists the currently configured NTP servers. Use the Add Row, Edit Row
and Delete Row buttons to manage this list; the Add Row and Edit Row
buttons open the NTP Server Configuration Dialog Box, page51-20.
