Network Time Protocol
Network Time Protocol (NTP) enables devices connected on local and worldwide networks to
synchronize their internal software and hardware clocks to the same time source. Synchronizing your
TransPort device to an NTP server is important for various functions, such as validating certificates
and timestamps on events in the event log. The TransPort device supports two implementations of
Network Time Protocol (NTP):
n NTP server — The device functions as an NTP server, allowing hosts that are attached to the
device's Local Area Networks to synchronize with the device. See Configure the device as an
NTP server for information about configuring your device as an NTP server.
n SNTP client — The device is synchronized with an NTP server, but does not function as an
NTPserver itself. See Configure the device as an SNTP client for information about configuring
your device as an NTP server.

Required Configuration Items
n At least one upstream NTP server for synchronization.
Additional Configuration Options
n Additional NTP servers for synchronization (up to a total of four servers).
n One or more configured LAN interfaces to accept NTP requests from.
This functionality is not available from the Web UI.
Command line
1. Configure the external NTP server that the TransPort device will use for system date and time
synchronization.
digi.router> ntp 1 server1 0.time.devicecloud.com
This can be repeated for up to 4 servers. For example:
digi.router> ntp 1 server2 1.time.devicecloud.com
2. Select the LAN interfaces from which the TransPort device will accept incoming NTP
synchronization requests. This is a comma-separated list:
digi.router> ntp 1 interfaces lan1,lan2
