Installation Manual

• Primary Time Server—Configures iLO to use a primary time server with the specified
address. You can enter the server address by using the server FQDN, IPv4 address, or IPv6
address.
• Secondary Time Server—Configures iLO to use a secondary time server with the specified
address. You can enter the server address by using the server FQDN, IPv4 address, or IPv6
address.
• Time Zone—Determines how iLO adjusts UTC time to obtain the local time, and how it
adjusts for Daylight Savings Time (Summer Time). In order for the entries in the iLO Event
Log and IML to display the correct local time, you must specify the server location time zone.
If you want iLO to use the time the SNTP server provides, without adjustment, select a time
zone that does not apply an adjustment to UTC time. In addition, that time zone must not
apply a Daylight Savings Time (Summer Time) adjustment. There are several time zones
that fit this requirement. One example is Atlantic/Reykjavik GMT, which is not east or west
of the Prime Meridian, and in which the time does not change in the Spring or Fall. If you
select the Atlantic/Reykjavik time zone, iLO web interface pages and log entries display the
exact time provided by the SNTP server.
NOTE: Configure the NTP servers to use Coordinated Universal Time (GMT).
iLO clock synchronization
SNTP allows iLO to synchronize its clock with an external time source. Configuring SNTP is
optional because the iLO date and time can also be synchronized from the following sources:
• System ROM (during POST only)
• Insight Management Agents (in the OS)
• Onboard Administrator (ProLiant server blades only)
• HPE OneView
Primary and secondary NTP server addresses can be configured manually or via DHCP servers.
If the primary server address cannot be contacted, the secondary address is used.
DHCP NTP address selection
When you use DHCP servers to provide NTP server addresses, the iLO Client Applications
use IPv6 first setting on the IPv6 page controls the selection of the primary and secondary NTP
values. When iLO Client Applications use IPv6 first is selected, a DHCPv6-provided NTP
service address (if available) is used for the primary time server and a DHCPv4-provided address
(if available) is used for the secondary time server.
To change the protocol-based priority behavior to use DHCPv4 first, clear the iLO Client
Applications use IPv6 first check box.
If a DHCPv6 address is not available for the primary or secondary address, a DHCPv4 address
(if available) is used.

iLO NIC auto-selection
iLO NIC auto-selection enables iLO to choose between the iLO Dedicated Network Port and the
iLO Shared Network port. At startup, iLO searches for network activity on the available ports,
and automatically selects one for use based on network activity.
