Parameters
keyid
: Specifies an authentication key number in the range of 1 to 4294967295.
Usage guidelines
If SNTP is enabled, the SNTP client is synchronized only to an NTP server that provides a trusted
key.
Before you use the command, make sure SNTP authentication is enabled and an authentication key
is configured. The key automatically changes to untrusted after you delete the key. In this case, you
do not need to execute the
undo sntp-service reliable authentication-keyid
command.
Examples
# Enable NTP authentication, and specify the MD5 encryption algorithm, with the key ID of 37 and
key value of
BetterKey
.
<Sysname> system-view
[Sysname] sntp authentication enable
[Sysname] sntp authentication-keyid 37 authentication-mode md5 BetterKey
# Specify this key as a trusted key.
[Sysname] sntp reliable authentication-keyid 37

broadcast address, a multicast address, or the IP address of the local clock.
vpn-instance vpn-instance-name

where
vpn-instance-name
is a case-sensitive string of 1 to 31 characters. If the NTP server is on the
public network, do not specify this option.
