5.1.7 Troubleshooting – Network PCs Cannot Sync
In order for clients on the network to be able to sync to VersaSync, several requirements must
be met:
1.
The PC(s) must be routable to VersaSync. Make sure you can access VersaSync Web UI
from a PC that is not syncing. If the PC cannot access the Web UI, a network issue likely
exists. Verify the network configuration.
2.
The network clients have to be configured to synchronize to VersaSync's address. For
additional information on syncing Windows PC's, see
https://spectracom.com/documents/synchronizing-windows-computers
section of this document also contains troubleshooting assistance for Windows syn-
chronization. For UNIX/Linux computer synchronization, please visit
http://www.ntp.org/
3.
If at least one PC can sync to VersaSync, the issue is likely not with VersaSync itself. The
only VersaSync configurations that can prevent certain PCs from syncing to the time
server are the NTP Access table and MD5 authentication. See "Configuring NTP Sym-
metric Keys" on page 98. A network or PC issue likely exists. A firewall may be blocking
Port 123 (NTP traffic), for example.
4.
NTP in VersaSync must be "in sync" and at a higher Stratum level than Stratum 15 (such
as Stratum 1 or 2, for example). This requires VersaSync to be either synced to its input
references or in Holdover mode. Verify the current NTP stratum level and the sync status.

Troubleshooting Software Update

When experiencing slow data transmission rates, or other network issues, it may be possible
that a system software update will be aborted due to a web server timeout during the transfer.
