4.2.5. NTP configuration
Device can use two NTP server for time synchronization. Detailed description of NTP settings
parameter is shown in Table 8. NTP settings description.
Table 8. NTP settings description
IP Address of NTP server.
When the server is reachable and at each poll interval, send a burst of eight
packets instead of the usual one packet. The spacing between the first and
the second packets is about 16s to allow complete call, while the spacing
between the remaining packets is about 2s. This is designed to improve
timekeeping quality with the server command and s addresses.
When the server is unreachable and at each poll interval, send a burst of eight
packets instead of the usual one. As long as the server is unreachable, the
spacing between packets is about 16s to allow complete call. Once the server
is reachable, the spacing between packets is about 2s. This is designed to
speed the initial synchronization acquisition with the server command and s
addresses and when ntpd is started with the -q option.
These options specify the minimum and maximum poll intervals for NTP
messages, in seconds to the power of two. The maximum poll interval
defaults to 10 (1,024 s), but can be increased by the maxpoll option to an
upper limit of 17 (36.4 h). The minimum poll interval defaults to 6 (64 s), but
can be decreased by the minpoll option to a lower limit of 4 (16 s).
