Network Configuration

This chapter describes how to edit the network host files after the adapter has been installed on your system. This chapter contains the following sections:

■“Configuring the Network Host Files” on page 23

■“Setting Up a 10-Gigabit Ethernet Network on a Diskless Client System” on page 25

■“Installing the Solaris Operating System Over a 10-Gigabit Ethernet Network” on page 27

■“Booting Over the 10-Gigabit Ethernet Network for Solaris x86 and Linux Systems” on page 31

Configuring the Network Host Files

After installing the driver software, you must create a hostname.nxgenumber file for the adapter’s Ethernet interface. You must also create both an IP address and a host name for its Ethernet interface in the /etc/hosts file.
