Network Interface Configuration

The network interface card (NIC) connectors are labeled physically on the server as follows:


TABLE C-1 NIC Connector Label

net0

First Broadcom interface

net1

Second Broadcom interface

net2

Second NVIDIA interface

net3

First NVIDIA interface


Some NICs will not be detected by the OS until the install.sh script from the Sun Fire X2100 M2 Server Tools and Drivers CD is run. Also, the ifconfig interface that is assigned to the NIC according to the operating system that you have installed might change after the drivers from the Sun Fire X2100 M2 Server Tools and Drivers CD are installed.

See the following sections for ifconfig assignments for each supported Linux or Solaris operating system. Later versions of the operating systems listed in the following sections have built-in support for both Broadcom and NVIDIA NICs.

Red Hat Enterprise Linux (RHEL) 4 Update 3

Before the Tools and Drivers CD drivers are installed, the NVIDIA interfaces are not detected for RHEL 4 Update 3, and cannot be used for PXE installation. Later versions of RHEL 4 contain support for both NVIDIA and Broadcom.

After installing the drivers from the Tools and Drivers CD, the NVIDIA NICs are detected and the interface order remains the same for the Broadcom NICs The order of the ifconfig interfaces is show in TABLE C-2.

Red Hat Enterprise Linux 3 Update 7

Before the Tools and Drivers CD drivers are installed, the NVIDIA interfaces are not detected in RHEL 3 Update 7 and cannot be used for PXE installation. Later versions of RHEL 3 contain support for both NVIDIA and Broadcom.

After installing the drivers from the Tools and Drivers CD, the NVIDIA NICs are detected and configured. The order of the ifconfig interface changed as shown in TABLE C-3.

Solaris 10 6/06 (Build 9a)

Before the Tools and Drivers CD drivers are installed, the NVIDIA interfaces are not detected. The Broadcom interfaces are bge0 and bge1. After installing the drivers from the Tools and Drivers CD, the NVIDIA NICs (nge0 and nge1) are detected and configured. The order of the ifconfig interface changed as shown in TABLE C-4.

SUSE Linux Enterprise Server (SLES) 9 SP 3

Before the Tools and Drivers CD drivers are installed, the Broadcom interfaces are not detected for SLES 9 SP3 and cannot be used for PXE installation. Later versions of SLES contain support for both NVIDIA and Broadcom.

After installing the drivers from the Tools and Drivers CD, the Broadcom NICs are detected. No change is seen on the NVIDIA interface order. The order of the ifconfig interface changed as shown in TABLE C-5.
