Ntp-Service Unicast-Server - H3C S5830V2 Series Command Reference Manual

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN to which the symmetric-passive peer belongs,
where vpn-instance-name is a case-sensitive string of 1 to 31 characters. If the symmetric-passive peer is
on the public network, do not specify this option.
authentication-keyid keyid: Specifies the key ID to be used for sending NTP messages to the peer, where
keyid is in the range of 1 to 4294967295. If this option is not specified, the local device and the peer do
not authenticate each other.
priority: Specifies the peer specified by ip-address or peer-name as the first choice under the same
condition.
source interface-type interface-number: Specifies the source interface for NTP messages. In an NTP
message the local device sends to its peer, the source IP address is the primary IP address of this interface.
interface-type interface-number represents the interface type and number.
version number: Specifies the NTP version, where number is in the range of 1 to 4 and defaults to 4.
Usage guidelines
When you specify a passive peer for the device, the device and its passive peer can be synchronized to
each other. If their clocks are in synchronized state, the clock with a high stratum level is synchronized to
the clock with a lower stratum level.
If you include vpn-instance vpn-instance-name in the undo ntp-service unicast-peer command, the
command removes the symmetric-passive peer 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
symmetric-passive peer with the IP address of ip-address in the public network.
Examples
# Specify the device with the IP address of 10.1.1.1 as the symmetric-passive peer of the device, configure
the device to run NTP version 4, and specify the source interface of NTP messages as VLAN-interface 1.
