Installing and Setting Up the Driver

This chapter explains how to download and install the nxge driver. The nxge gigabit Ethernet driver (nxge(7D)) is a multi-threaded, loadable, clonable, GLD-based STREAMS driver. The nxge driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of nxge instances and for nxge instances to be aggregated. See the dladm(1M) man page for more details on configuring the data-link interfaces and link aggregations.

This chapter contains the following sections:

■“Downloading and Installing the Driver on a Solaris SPARC or x86 Platform” on page 7

■“Downloading and Installing the Driver on a Linux Platform” on page 10

Downloading and Installing the Driver on a Solaris SPARC or x86 Platform

If your system uses the Solaris SPARC or x86 operating system you will need to download and install the nxge device driver for Solaris platforms.

▼To Download the Driver on a Solaris Platform

1.Locate and download the nxge device driver software at the following web site:
