Installation Manual

• Enable DHCPv6 in Stateful Mode (Address)—Select this check box to allow iLO to request
and configure IPv6 addresses provided by a DHCPv6 server.
◦ Use DHCPv6 Rapid Commit—Select this check box to instruct iLO to use the Rapid
Commit messaging mode with the DHCPv6 server. This mode reduces DHCPv6 network
traffic, but might cause problems if it is used in networks where more than one DHCPv6
server can respond and provide addresses.
• Enable DHCPv6 in Stateless Mode (Other)—Select this check box to enable iLO to request
settings for NTP and DNS service location from the DHCPv6 server.
◦ Use DHCPv6 Supplied Domain Name—Select this check box to use the DHCPv6
server-supplied domain name.
◦ Use DHCPv6 Supplied DNS Servers—Select this check box to use IPv6 addresses
provided by the DHCPv6 server for DNS server locations. This setting can be enabled
at the same time as the IPv4 DNS server location options.
◦ Use DHCPv6 Supplied NTP Servers—Select this check box to use IPv6 addresses
provided by the DHCPv6 server for NTP server locations. This setting can be enabled
at the same time as the IPv4 NTP server location options.
When Enable DHCPv6 in Stateful Mode (Address) is selected, Enable DHCPv6 in
Stateless Mode (Other) is always selected by default because it is implicit in the DHCPv6
Stateful messages that are required between iLO and the DHCPv6 server.
DNS server settings
• Primary DNS Server, Secondary DNS Server, and Tertiary DNS Server—Enter the IPv6
addresses for the DNS service.
When DNS server locations are configured on both the IPv4 and IPv6 pages, both sources
are used. Preference is given according to the iLO Client Applications use IPv6 first
configuration option, primary sources, then secondary, and then tertiary.
• Enable DDNS Server Registration—Specify whether iLO registers its IPv6 address and
name with a DNS server.
General IPv6 settings
• Static IPv6 Address 1, Static IPv6 Address 2, Static IPv6 Address 3, and Static IPv6
Address 4—Enter up to four static IPv6 addresses and prefix lengths for iLO. Do not enter
link-local addresses.
• Static Default Gateway—Enter a default IPv6 gateway address for cases in which no router
advertisement messages are present in the network.
• Static Route #1, Static Route #2, and Static Route #3—Enter static IPv6 route destination
prefix and gateway address pairs. Specify the prefix length for the destination. Link-local
addresses are not allowed for the destination, but are allowed for the gateway.
iLO features that support IPv6
iLO 4 1.20 and later supports IPv6 in the iLO Dedicated Network Port configuration. It is not
supported with the Shared Network Port configuration. The IETF introduced IPv6 in response to
the ongoing depletion of the IPv4 address pool. In IPv6, addresses are increased to 128 bits in
length, to avoid an address shortage problem. iLO supports the simultaneous use of both protocols
through a dual-stack implementation. All previously available iLO features are still supported in
IPv4.
