'failed to get clock through NTP' on backup unit
'get log event' on backup unit shows 'failed to get clock though NTP' 'failed to get clock through NTP' on backup unit

In ScreenOS 4.0.1 or above, the command 'set ntp no-ha-sync' turns off the clock synchronization between the master and backup device


In ScreenOS 3.1.0, NTP update is only performed on master device.


In ScreenOS 4.0.x, with NSRPv2, both master & backup units are able to do NTP update. The manage-ip must be set on the outgoing interface (separate from the physical IP address).

The master unit will synchronize the system clock to the backup whenever it gets a NTP update.
