Description
Use the ntp-service unicast-server command to configure NTP server mode. Use
the undo ntp-service unicast-server command to disable NTP server mode.
By default, no NTP server mode is configured. When you do not specify a version
number, the default version number is 3. When you do not specify
authentication-keyid, authentication is disabled.
The command announces to use the remote server at ip-address as the local time
server. ip-address specifies a host address other than a broadcast address, multicast
address, or the IP address of a reference clock. By operating in client mode, a local
device can be synchronized by a remote server, but not synchronize any remote
server.
Example
# Designate the server at 128.108.22.44 to synchronize the local device and use NTP
version 3.
