2310 CHAPTER 152: NTP CONFIGURATION COMMANDS

Description	Use the ntp-servicerefclock-mastercommand to configure the local clock as a
	reference source for other devices.
	Use the undo ntp-servicerefclock-mastercommand to remove the local clock
	as a reference source.
n	The stratum level of a clock defines the clock precision. The value range is 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 and cannot be
	used as a reference clock.
Example	# Specify the local clock as the reference source, with the stratum level of 3.

	[Sysname] ntp-service refclock-master 3

Parameter keyid: Authentication key number, in the range of 1 to 4294967295.

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

Use the ntp-service reliable authentication-keyid command to remove an authentication key as a trusted key.

No authentication key is configured to be trusted by default.

Example # Enable NTP authentication, specify to use MD5 encryption algorithm, with the key ID of 37 and key value of “BetterKey”, and specify that this key is a trusted key.
