Table51-21 NTP Server Configuration Dialog Box
Element Description
IP Address Enter or Select the IP address of the NTP server.
Preferred If checked, this NTP server is the preferred server when multiple
servers are similarly accurate.
NTP uses an algorithm to determine which server is the most accurate
and synchronizes to that one. If multiple servers are of similar accuracy,
then this option specifies which of those servers to use. However, if a
server is significantly more accurate than the preferred one, the security
appliance uses the more accurate server. For example, the security
appliance uses a server of stratum 2 over a server of stratum 3 that is
preferred. We recommend that you configure an NTP server as
preferred only when multiple servers are likely to have the same
stratum.
Interface Enter or Select the interface used for NTP traffic, if you want to
override the default interface in to the routing table.
Authentication Key The parameters in this section set the authentication key attributes if you want to
use MD5 authentication for communicating with the NTP server.
Key Number Enter the ID for this authentication key. The NTP server packets must
also use this key ID. If you previously configured a key ID for another
server, you can select it in the list; otherwise, type a number between 1
and 4294967295.
Trusted Sets this key as a trusted key. You must select this option for
authentication to work.
Key Value Enter the authentication key as a string up to 32 characters in length.
Confirm Re-enter the authentication key to verify it is correct.
