The Sun server SP or CMM automatically broadcasts a DHCPDISCOVER packet when power is applied to the Sun server platform. If you have an established DHCP server on the network, the DHCP server automatically returns a DHCPOFFER packet containing IP address(es) and other network configuration information to the requesting server SP(s) or CMM(s).
You can choose to have a DHCP server assign Ethernet IP address(es) for you, or you can configure the DHCP server to assign specific Ethernet IP address(es) by providing the MAC address of the SP(s). For more information, consult the DHCP server user documentation. For more information about how to obtain the MAC address of server SP or CMM, see SP Network Interface MAC Address.
