NTP Service Control and Status¶
Enable the NTP Service¶
Enable the NTP server:
tnsr(config)# ntp enable
tnsr(config)#
Disable the NTP Service¶
Similar to the NTP enable command, disable the NTP service from
configuration mode:
tnsr(config)# ntp disable
tnsr(config)#
Check the NTP Service Status¶
Check the status of the NTP services from configuration mode using service ntp
<namespace> status, where <namespace> is the namespace where NTP is
running (host or dataplane):
tnsr(config)# service ntp host status
* ntpd.service - Network Time Service

View NTP Peers¶
The NTP peer list shows the peers known to the NTP daemon, along with information about their network availability and quality. For more information on peer associations, see View NTP Associations.
tnsr(config)# show ntp peers

View NTP Associations¶
The NTP peer associations list shows how the NTP daemon is using each peer, along with its status. These peers are listed by ID. For more information on each peer, see View NTP Peers.
tnsr(config)# show ntp associations
