Item Description
Clock status
Displays the synchronization status of the system clock.
Local Reference Source
Set the IP address of the local clock source to 127.127.1.u, where u
ranges from 0 to 3, representing the NTP process ID.
•
If the IP address of the local clock source is specified, the local
clock is used as the reference clock, and thus can provide time for
other devices.
•
If the IP address of the local clock source is not specified, the local
clock is not used as the reference clock.
Stratum
Set the stratum level of the local clock.
The stratum level of the local clock decides the precision of the local
clock. A higher value indicates a lower precision. A stratum 1 clock
has the highest precision, and a stratum 16 clock is not synchronized
and cannot be used as a reference clock.
Source Interface
Set the source interface for an NTP message.
If you do not want the IP address of a certain interface on the local
device to become the destination address of response messages, you
can specify the source interface for NTP messages, so that the source
IP address in the NTP messages is the primary IP address of this
interface. If the specified source interface is down, the source IP
address of the NTP messages sent is the primary IP address of the
outbound interface.
