In this mode, set the address of the NTP server from which the Switch
requests the time. The Switch regularly requests time information from the
NTP server, and updates the local time based on the obtained time
information. (You can configure the interval for the requests issued to the NTP
server.)
You can register a maximum of two NTP server addresses. The address that
is registered first is called the primary address. The address that is registered
second is called the secondary address. If the Switch fails to obtain the time
from the primary NTP server address, the Switch requests time information
from the secondary NTP server address.
