If VersaSync is synchronized to another NTP Server or reference, and that server or ref-
erence subsequently loses sync or becomes unavailable (with no other higher priority input
references being present and valid), VersaSync will then go into the Holdover mode. It will
remain in Holdover mode until any enabled and valid input reference becomes available
again, or until the Holdover period expires, whichever occurs first.
During Holdover mode, NTP will remain at the same Stratum level it was before entering
the Holdover mode and can continue to be the reference to the network. However, if no
input reference becomes available before the Holdover period expires, Time Sync will be
lost and shortly thereafter, NTP will report to the network that it is now at Stratum15. A
status of Stratum15 will cause the network to ignore VersaSync as an NTP time reference.
For more information about Holdover, see "Holdover Mode" on page193.
The NTP Servers and NTP Peers Panels
The NTP Servers and NTP Peers panels display which servers in the network are set up at
higher or equal Stratums (Servers or Peers, respectively), and their configurations. These
panels are also used to add, configure, or remove NTP Servers and Peers.
Note: For information on how to view NTP Clients, see "Viewing NTP Cli-
ents" on page102.
The NTP Servers and NTP Peers panels are part of the NTP Setup screen (see "The NTP
Setup Screen" on page99), which can be accessed via MANAGEMENT > NETWORK:
NTP Setup.
Information provided in the NTP Servers and NTP Peers panels
The following columns are used to break down the status information for recognized NTP
Servers and NTP Peers.
