Key number key-number ranges from 1 to 4294967295
Designating an Interface to Transmit the NTP Message
If the local equipment is configured to transmit all NTP messages, these packets
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.
Setting the NTP Master Clock
This configuration task sets the external reference clock or the local clock as the
NTP master clock.
Perform the following configurations in system view.
ip-address specifies the IP address 127.127.1.u of a reference clock, in which u
ranges from 0 to 3. stratum specifies how many strata 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.
Enabling or Disabling an Interface to Receive an NTP Message
