Network: REBOOT
This is a way to reboot the Meridian II and is necessary after you’ve finished configuring the network
parameters. Until you do this, the network parameters that are shown will be the active settings, NOT
the new settings. The new settings will become active after you reboot.
NTP Menu
The NTP Menu is selected from the Main Menu and provides access to the Status, I/O Statistics and
Setup displays described below:
NTP: Status
This display provides information associated with the NTP Subsystem.
Stratum: This stratum field has three possible values:
Stratum 1:
The server is fully synchronized and accurate.
Stratum 2:
The server is synchronized to a Stratum 1 server.
Stratum x:
The server is synchronized to a Stratum x server.
Stratum 16:
The server is unsynchronized. NTP clients will not use a Stratum 16
server.
Source:
The synchronization source is named here. For the Meridian II the source is GPS,
IP address of upstream source, or none.
Offset: The NTP offset indicates the accuracy of the NTP system clock relative to the GPS
Subsystem clock. Initially, if the offset between the NTP system clock and the GPS
Subsystem clock is large the display will indicate “not available”. After the GPS
Subsystem locks, the NTP clock will synchronize to the GPS Subsystem. Once
synchronization is complete, the typical offsets will range over approximately
+/- 1 microsecond.
LI Bits: Shows the status of the leap indicator bits as sent by the Meridian II time server to the
clients in the NTP reply packets. Leap seconds occur every 2-3 years.
Possible indicator values are:
00:
Normal, locked operation.
01:
Leap second insertion event will occur after 23:59:59 UTC.
10:
Leap second deletion event will occur after 23:59:58 UTC.
11:
Fault. Unsynchronized state.
NTP: I/O Statistics (I/O_Stats)
This display shows some key information regarding the operation of the NTP daemon. The informa-
tion includes the time since reset and the counts of received, sent and dropped packets, and the sent
packet rate.
NTP: Setup
This display provides access to the NTP broadcast and multicast settings and provides you with a
convenient means of checking the current configuration and allows limited setup. You may also
