system (others may be reported by other NTP peers or servers):
AUTH STATUS —Indicates if the selected reference is using MD5 authentication. "None"
indicates authentication not being used.
LAST —The number of seconds it's been since this reference was last polled for its time.
POLL —The poll interval, how often SecureSync is polling this NTP reference for its time.
DELAY (ms) —The measured one-way delay between SecureSync and its selected ref-
erence.
To remove a server (and its associated configurations), select the "Clear" option at the end of its

NOTE – NTP clients of the SecureSync are viewable through the View NTP Clients
option In the Actions panel of the NTP Setup screen. See"NTP Servers & Peers
(Stratum Synchronization)" on page 98.
NOTE – In order for other NTP servers to be a valid reference, "NTP" must be
enabled as both the Time and 1PPS references in the Reference Priority table. See
"Configuring Input Reference Priorities" on page 153.
NOTE – In order for NTP configuration changes to take effect, NTP should be dis-
abled and then enabled after any configurations changes have been made. NTP can
be stopped and restarted from the MANAGEMENT/NETWORK/NTP Setup page, in
the NTP Service panel on the left-hand side of the page. See "NTP Servers & Peers
(Stratum Synchronization)" on page 98 and "NTP Servers & Peers (Stratum Syn-
chronization)" on page 98.
