7.2.5 Designate an Interface to Transmit NTP Message

If the local equipment is configured to transmit all the NTP messages, these packets
will have the same source IP address, which is taken from the IP address of the
designated interface.
Perform the following configurations in system view.

An interface is specified by interface-name or interface-type interface-number. The
source address of the packets will be taken from the IP address of the interface. If the
ntp-service unicast-server or ntp-service unicast-peer command also designates a
transmitting interface, use the one designated by them.

7.2.6 Set NTP Master Clock

This configuration task is to set the external reference clock or the local clock as the
NTP master clock.
Perform the following configurations in system view.
Table 7-11 Set the external reference clock or the local clock as the NTP master clock
Set the external reference clock or the
local clock as the NTP master clock.

ip-address specifies the IP address 127.127.t.u of a reference clock, in which t ranges
from 0 to 37 and u from 0 to 3. stratum specifies how many stratums the local clock
belongs to and ranges from 1 to 15. If no IP address is specified, the system defaults to
setting the local clock as the NTP master clock. You can specify the stratum parameter.

7.2.7 Enable/Disable an Interface to Receive NTP Message

This configuration task is to enable/disable an interface to receive NTP message.
Perform the following configurations in VLAN interface view.
