Syntax

Parameters
ip-address: IP address of the symmetric-passive peer. It must be a host address, rather
than a broadcast address, a multicast address or the IP address of the local clock.
peer-name: Host name of the symmetric-passive peer, a string of 1 to 20 characters.
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.
priority: Specifies the peer designated by ip-address or peer-name as the first choice
under the same condition.
source-interface interface-type interface-number: Specifies an interface for sending
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 3 and
defaults to 3.
Description
Use the ntp-service unicast-peer command to designate a symmetric-passive peer
for the device.
Use the undo ntp-service unicast-peer command to remove the symmetric-passive
peer designated for the device.
No symmetric-passive peer is designated for the device by default.
Examples
# Designate the device with the IP address of 10.1.1.1 as the symmetric-passive peer
of the device, and configure the device to run NTP version 3, and send NTP messages
through VLAN-interface 1.
