GPS Antenna OK: The antenna coax cable was just connected or an open or short in the
antenna cable was being detected but is no longer being detected.
Frequency Error:The oscillator’s frequency was measured and the frequency error was
too large. Or, the frequency couldn’t be measured because a valid input reference was
not available.
Frequency Error cleared:The Frequency Error alarm was asserted but was then cleared.
In Holdover: Input references were available, but all input references have since been
lost. If the references are not restored before the Holdover period expires, time sync will
be lost.
No longer in Holdover: Input references were lost at one point (or declared not valid), but
have since been restored OR the Input references were not restored before the Holdover
period expired (Time Sync alarm is asserted).
In Sync: VersaSync is synchronized to its Time and 1PPS inputs.
Not In Sync: VersaSync is not synchronized to its Time and 1PPS inputs and is not cur-
rently in Holdover. NTP will indicate to the network that it is Stratum 15 and so the time
server likely be ignored as a time reference.
Sending trap for event 1 (SNMPSAD): An SNMP trap was sent by the SNMP agent to the
SNMP Manager. The event number in this entry indicates which SNMP trap was sent.
The Unit has Rebooted: VersaSync was either rebooted or power cycled.
Journal Log
Displays log entries created for all configuration changes that have occurred (such as creating
a new user account, for example).
NTP Log
The NTP log displays operational information about the NTP daemon, as well as NTP through-
put statistics (e.g., packets/sec.). Examples for entries in this log include indications for when
NTP was synchronized to its configured references (e.g., it became a Stratum1 time server), as
well as stratum level of the NTP references.
The NTP throughput statistics data can be utilized to calculate mean values and the standard
deviation.
Example log entries include:
Synchronized to (IP address), stratum=1: NTP is synchronizing to another Stratum 1 NTP
server.
ntp exiting on signal 15: This log entry indicates NTP is now indicating to the network that
it is a Stratum 15 time server because it is not synchronized to its selected reference.
Time reset xxxxx s: These entries indicate time corrections (in seconds) applied to NTP.
No servers reachable: NTP cannot locate any of its configured NTP servers.
