Resetting the Device Using the CLI
The following table summarizes the equivalent CLI commands for performing a reset of the device
via the CLI:.
The following is an example of the CLI command:
Configuring SNTP Settings
The device supports the Simple Network Time Protocol (SNTP). SNTP assures accurate network
device clock time synchronization up to the millisecond. Time synchronization is performed by a
network SNTP server. The device operates only as an SNTP client, and cannot provide time
services to other systems.
The device can poll the following server types for the server time:
• Unicast
• Anycast
• Broadcast
Time sources are established by Stratums. Stratums define the accuracy of the reference clock. The
higher the stratum (where zero is the highest), the more accurate the clock. The receives
time from stratum 1 and above.
The following is an example of stratums:
•
Stratum 0
— A real time clock is used as the time source, for example, a GPS system.
•
Stratum 1
— A server that is directly linked to a Stratum 0 time source is used. Stratum 1
time servers provide primary network time standards.
•
Stratum 2
— The time source is distanced from the Stratum 1 server over a network path. For
example, a Stratum 2 server receives the time over a network link, via NTP, from a Stratum 1
server.
