3.4.3.2 NTP Client Configuration
In Advanced View, after you have set the Bridge’s internal clock
to within 1000 seconds of the current time on the network, you
can enable the Bridge to synchronize its clock with the time
disseminated by up to three configured NTP servers.
Once the Bridge’s system clock is successfully synchronized
with NTP server time, NTP manages the drift between the time
on the Bridge (the NTP client) and the time maintained by the
NTP server(s) for the network. If the Bridge is out of sync with
NTP server time, NTP automatically corrects the Bridge’s
system clock.
If an NTP server is configured with a shared key to
authenticate NTP transactions and you specify that key on the
Bridge, the Bridge will require the shared key for NTP
transactions with that server. If you do not specify a key for a
configured NTP server, the Bridge will synchronize its clock
with that of the NTP server without shared-key authentication.
The Bridge supports up to three NTP servers.
NTP Timeout applies globally to the configured server(s). Three
settings establish each NTP server individually.

Time Configuration
frame, all platforms
NTP Timeout - globally determines the interval, in minutes
from
5 to 1440, of silence from configured NTP servers
after which you will be notified that the Bridge cannot reach
any of its configured and enabled NTP servers. The default
NTP Timeout is 240 minutes.
Server State 1–3 - establishes whether the NTP server
(when configured) will be used (
Enabled) to set system time
on the Bridge. All three are
Disabled by default.
IP /Hostname 1–3 - provides the IP address or fully qualified
hostname of the NTP server.
New/Confirm Server Key 1–3 - provides the key in effect for
the NTP server.
The Bridge’s NTP client function is disabled by default, and no
NTP servers are configured.
