Sntp Reliable Authentication-Keyid - H3C S5830V2 Series Command Reference Manual

Usage guidelines
When you specify an IPv6 NTP server for the device, the device is synchronized to the NTP server, but the
NTP server is not synchronized to the device.
If you include vpn-instance vpn-instance-name in the undo ntp-service unicast-server command, the
command removes the NTP server with the IP address of ip-address in the specified VPN. If you do not
include vpn-instance vpn-instance-name in this command, the command removes the NTP server with the
IP address of ip-address in the public network.
If the specified IPv6 address of the NTP server is a link local address, you must specify the source
interface for NTP messages and cannot specify a VPN for the NTP server.
Examples
# Specify the IPv6 NTP server 2001::1 for the device.
<Sysname> system-view
[Sysname] sntp ipv6 unicast-server 2001::1

Usage guidelines
If SNTP is enabled, the SNTP client is only synchronized to an NTP server that provides a trusted key.
Before you use the command, make sure that 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.
