Web Interface
Use
INSTALL
to upload the key and/or certificate files to the SyncServer.
After uploading the keys, click the
RESTART
button
to make the key(s) active
on the Syn-
cServer.
Upon making the added keys active, the SyncServer will be able to authenticate NTP pack-
ets from NTP servers that use those keys.
Newly added NTP Autokeys are not active until the user clicks
RESTART
.
RESTART Button
After changing the NTP configuration, click the
RESTART
button to put the new configuration
into effect. While the NTP daemon restarts, its services are temporarily unavailable, and it
generates the following alarm events: NTP Stratum Change, NTP System Peer Change,
NTP Leap Change.
NTP - Prefs
The settings on this page determine whether the NTP daemon, once synchronized, can
report an unsynchronized state.
Note: Microsemi recommends keeping the default
Standard NTP Rules
setting below. The
Override Behavior
setting is mostly a "compatibility" setting for custom systems built around
legacy TrueTime GPS clocks such as the NTS-200.
Note: The SyncServer S350i does not include a GPS receiver.
Out of the three following stages of operation, the
NTP - Prefs
settings only apply during the
Loss of All References
stage:
1.
Startup
: Upon starting, before synchronizing with any NTP associations, the NTP dae-
mon reports to potential NTP clients that it is unsynchronized by setting leap indicator to
11 and stratum to 16.
2.
Typical Operation
: After synchronizing to an NTP association the NTP daemon uses leap
indicator and stratum normally. Leap indicator reports whether a leap event is pending
(usually 00 - no alarm). Stratum reports the stratum of the NTP daemon relative to the
system peer
(usually 1 through 3).
3.
Loss of All References
: If the NTP daemon cannot get the time from any association:
n
With
Standard NTP Rules
(Factory Default) The
stratum
and
leap indicator
remain
the same as they were in the
Typical Operation
stage. The
system peer
remains
the unchanged, but the
reference time stamp
isn't updated and the
reach
statistic
gradually decreases to zero.
n
With
Override Behavior
, if the estimated time error exceeds the
Time Error Limit
on
the
TIMING - Holdover
page,
stratum
reports 16 and
leap indicator
reports 11, as
they did during in the
Startup
stage.
After
Loss of All References
, if the NTP daemon synchronizes with an NTP association
again, it resumes
Typical Operation
.
