Configuring SNTP settings
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 (blade servers only)
To use iLO SNTP, you must have at least one NTP server available on your management network.
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. You must have
the Configure iLO Settings privilege to change these settings.
NOTE:
IPv6 is not supported in the Shared Network Port configuration.
To configure the SNTP settings:
1.
Navigate to the Network
→iLO Dedicated Network Port or Network→Shared Network Port
page.
2.
Click the SNTP tab, as shown in
Figure 35 SNTP Settings page (iLO Dedicated Network Port)
3.
Do one of the following:
•
Select the Use DHCPv4 Supplied Time Settings check box, the Use DHCPv6 Supplied Time
Settings check box, or both check boxes to use DHCP-provided NTP server addresses.
Note the following configuration prerequisites:
◦
To configure a DHCPv4-provided NTP service configuration, you must first enable
DHCPv4 on the IPv4 tab.
◦
To configure a DHCPv6-provided NTP service configuration, DHCPv6 Stateless Mode
must be enabled on the IPv6 tab.
When you use DHCP servers to provide NTP server addresses, the iLO Client Applications
use IPv6 first setting controls the selection of the primary and secondary NTP values.
When iLO Client Applications use IPv6 first is selected on the IPv6 tab, 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.
