How to Identify Installed Network Ports

Use these steps to help you identify the logical names of your physical network ports. This information will be necessary during the installation and configuration of the operating system.

1. Identify your installed network ports.

   A fully loaded Sun Fire X4800 server could have the following ports:

   • FEM: This is a Broadcom 10GbE port. These ports require a Fabric Expansion Module (FEM) installed on each CPU module for each NEM (for a total of two per CPU module).

   • PCIe EM: This is a PCIe ExpressModule (EM) slot. There are two assigned per CPU module. If a network interface card is installed, it can have more than one port.

   • NIC: This is an Intel 1GbE port. There are two assigned per CPU module.

   
   
2. Run the Oracle Hardware Assistant and proceed to the System Information screen to view logical name assignment of your installed network ports.

   Even if you do not plan on using the Oracle Hardware Assistant to assist in the operating system installation, it will provide important information in identifying installed components. For information on using Oracle Hardware Assistant, see Oracle Hardware Installation Assistant.

   • Installed FEM devices are labeled as 10 Gigabit Ethernet PCI-E (GigaSwift).

   • Installed NIC devices labeled as Intel 82576 Gigabit Network connection.

   • Installed PCIe EM devices have vendor: as the label prefix. An example might be: vendor: Intel Corporation product: 82571EB Gigabit Ethernet Controller.

3. In the table below, make a note of the actual ports installed in the system and their logical names as shown in the Oracle Hardware Assistant System Information screen.

   During system boot, ports are enumerated and assigned logical names based on the system PCIe scan order. Note that although Oracle Hardware Assistant lists the correct logical name (eth0, eth1, eth2, etc.), it does not necessarily list ports by logical name order.

   
   

   PCIe Scan Order Port Identifier Does a Network Port at this Location Physically Exist in the System? Is This Port Active (listed as Configured in Oracle Hardware Assistant)? Logical Name Assigned in Oracle Hardware Assistant (eth0, eth1, etc.) 1 EM0.1 2 EM0.0 3 FEM0.0 4 FEM0.1 5 NIC0.0 6 NIC0.1 7 NIC3.0 8 NIC3.1 9 EM3.1 10 EM3.0 11 FEM3.0 12 FEM3.1 13 NIC1.0 14 NIC1.1 15 EM1.1 16 EM1.0 17 FEM1.0 18 FEM1.1 19 NIC2.0 20 NIC2.1 21 EM2.1 22 EM2.0 23 FEM2.0 24 FEM2.1

   Use this information during software installation to ensure network ports are configured correctly.
