source-interface : Specify the name of an interface.
interface-name
: Specify the interface name. When a local device sends an NTP
message to a peer, the source IP address of the message is taken from the address
of the interface.

Description
Use the ntp-service unicast-peer command to configure NTP peer mode.
Use the undo ntp-service unicast-peer command to cancel NTP peer mode.
By default, version number
number
defaults to 3, the authentication is disabled,
and the local server is not the first choice.
This command sets the remote server at
ip-address
as a peer of the local
equipment, which operates in symmetric active mode.
ip-address
specifies a host
address other than an IP address of broadcast, multicast, or reference clock. By
operating in this mode, a local device can synchronize and be synchronized by a
remote server.
Example
Configure the local equipment to synchronize or be synchronized by a peer at
128.108.22.44. Set the NTP version to 3. The IP address of the NTP packets are
taken from that of Vlan-Interface1.
