Once the DHCP server has been configured, it is then very easy to configure a Solaris client. When installing the client, you will be asked whether you wish to install DHCP support. At this point, you should answer yes. Accordingly, you will not be asked to enter a static IP address as per a normal installation, as this will be supplied by the DHCP server with a DHCPOFFER message.
If you wish to enable support for DHCP on a client that has already been installed, you will need to use the sys-unconfig command, which can be used on all systems to reconfigure network and system settings without having to manually edit configuration files. The sys-unconfig command reboots the system in order to perform this task, so users should be given plenty of warning before reconfiguration commences. Again, you will be asked during configuration to install DHCP support, to which you should answer yes.
When configured, the DHCP client (dhcpagent) is managed by ifconfig-although dhcpagent can be started manually, it is most often started by ifconfig with respect to a specific interface. This process allows a lease to be initially obtained and subsequently renewed if the interface is still in use.
