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.
Table 7-10 Designate an interface to transmit NTP message
Operation Command
Designate an interface to transmit NTP
message
ntp-service source-interface
{ interface-name | interface-type
interface-number }
Cancel the interface to transmit NTP
message
undo ntp-service source-interface
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
Operation Command
Set the external reference clock or the
local clock as the NTP master clock.
ntp-service refclock-master
[ ip-address ] [ stratum ]
Cancel the NTP master clock settings
undo ntp-service refclock-master
[ ip-address ]
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
