Installing Network Time Protocol (NTP) is optional but strongly recommended. If you install NTP, install it on each service node in your cloud deployment.
NTP helps ensure a consistent time of day across all of the service nodes in the cloud. If you enable NTP in a network, configure the service nodes to obtain their time over the network.
If IP multicast is enabled on the IP subnets on which the service nodes reside, you can leverage IP multicast to configure NTP.
If IP multicast is not enabled on the IP subnets on which the service nodes reside, configure NTP manually.
Before You Begin
If you do not want to use multicast for NTP, you must configure an NTP server.
controller# pkg install ntp
controller# cp /etc/inet/ntp.client /etc/inet/ntp.conf
The configuration file would resemble the following example:
# multicastclient 224.0.1.1 ... server system1.example.com iburst server system2.example.com iburst # server server_name3 iburst
controller# svcadm enable ntp
