Use the ntp command to configure persistent synchronization of the GigaVUE H Series node’s system clock with an NTP server. Separate arguments let you add servers and enable the use of NTP generally. You can also use the ntpdate command to perform one-time synchronization of the system clock. Refer to ntpdate for more information.
The ntp command has the following syntax:
ntp
authentication enable
authentication-key <key number>
