Ntp-Service Refclock-Master; Ntp-Service Reliable Authentication-Keyid - H3C SR6600 Command Reference Manual

ttl ttl-number: Specifies the TTL of NTP multicast messages, where ttl-number is in the range of 1 to 255.
The default is 16.
version number: Specifies the NTP version. The value range for the number argument is 1 to 4, and the
default is 3.
Examples
# Configure the device to operate in multicast server mode and send NTP multicast messages on
GigabitEthernet 2/0/1 to the multicast address 224.0.1.1, using key 4 for encryption, and set the NTP
version to 3.

ntp-service refclock-master

Use ntp-service refclock-master to configure the local clock as a reference source for other devices.
Use undo ntp-service refclock-master to remove the configuration.
Syntax
ntp-service refclock-master [ ip-address ] [ stratum ]
undo ntp-service refclock-master [ ip-address ]

3: Manage level
Parameters
ip-address: IP address of the local clock, which is 127.127.1.u, where u is the NTP process ID that is in the
range of 0 to 3. If you do not specify ip-address, it defaults to 127.127.1.0.
stratum: Specifies the stratum level of the local clock, in the range of 1 to 15. The default is 8.
Usage guidelines
The stratum level of a clock defines the clock precision. The value is in the range of 1 to 16. The clock
precision decreases from stratum 1 to stratum 16. A stratum 1 clock has the highest precision, and a
stratum 16 clock is not synchronized.
Examples
# Specify the local clock as the reference source, with the stratum level 3.
<Sysname> system-view
[Sysname] ntp-service refclock-master 3

ntp-service reliable authentication-keyid

Use ntp-service reliable authentication-keyid to specify that the created authentication key is a trusted
key. When NTP authentication is enabled, a client can be synchronized only to a server that can provide
a trusted authentication key.
Use undo ntp-service reliable authentication-keyid to remove the configuration.
