Network time protocol
NTP synchronizes timekeeping among a set of distributed time servers and clients. The protocol coordinates time distribution in a large,
diverse network. NTP clients synchronize with NTP servers that provide accurate time measurement. NTP clients choose from several
NTP servers to determine which oers the best available source of time and the most reliable transmission of information.
To get the correct time, OS10 synchronizes with a time-serving host. For the current time, you can set the system to poll specic NTP
time-serving hosts. From those time-serving hosts, the system chooses one NTP host to synchronize with and acts as a client to the NTP
host. After the host-client relationship establishes, the networking device propagates the time information throughout its local network.
The NTP client sends messages to one or more servers and processes the replies as received. Information included in the NTP message
allows each client/server peer to determine the timekeeping characteristics of its other peers, including the expected accuracies of their
clocks. Using this information, each peer selects the best time from several other clocks, updates the local clock, and estimates its
accuracy.
NOTE: OS10 supports both NTP server and client roles.
Enable NTP
NTP is disabled by default. To enable NTP, congure an NTP server to which the system synchronizes. To congure multiple servers, enter
the command multiple times. Multiple servers may impact CPU resources.
• Enter the IP address of the NTP server to which the system synchronizes in CONFIGURATION mode.
