Procedure
1. Click iLO Dedicated Network Port or iLO Shared Network Port in the navigation tree.
2. Click the SNTP tab.
3. Do one of the following:
• To use DHCP-provided NTP server addresses, enable Use DHCPv4 Supplied Time Settings,
Use DHCPv6 Supplied Time Settings, or both.
• Enter NTP server addresses in the Primary Time Server and Secondary Time Server boxes.
4. If you selected only Use DHCPv6 Supplied Time Settings, or if you entered a primary and secondary
time server, select the server time zone from the Time Zone list.
5. Configure the NTP time propagation setting.
For blade servers, this setting is called Propagate NTP or OA Time to Host.
For nonblade servers, this setting is called Propagate NTP Time to Host.
6. To save the changes you made on the SNTP Settings page, click Apply.
7. If you are finished configuring the iLO network settings on the General, IPv4, IPv6, and SNTP tabs,
click Reset to restart iLO.
It might take several minutes before you can re-establish a connection.
SNTP options
Use DHCPv4 Supplied Time Settings
Configures iLO to use a DHCPv4-provided NTP server address.
Use DHCPv6 Supplied Time Settings
Configures iLO to use a DHCPv6-provided NTP server address.
NTP time propagation setting
The name of this setting differs depending on the server type.
• Propagate NTP Time to Host—Determines whether the server time is synchronized with the iLO
time during the first POST after AC power is applied or iLO is reset to the default settings.
If you use this setting, the UEFI system time will change to match the iLO clock at every POST.
• Propagate NTP or OA Time to Host—Determines whether the server time is synchronized with
the iLO time during the first POST after AC power is applied, a blade is inserted, or iLO is reset to
the default settings.
When this setting is enabled, and NTP is not configured or functional, the server time is
synchronized with the Onboard Administrator time.
If you use this setting, the UEFI system time will change to match the iLO clock at every POST.
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.
