Configure Windows Network Communication Settings With Multiple Network Interfaces

A P P E N D I X A

This appendix provides information you should consider when configuring the Windows network communication settings with multiple Sun Blade X6220 Series network interfaces.

Topics in this appendix include:

Determine Which Network Data Ports Are Actively Connected to a Network.

Confirm Physical Port MAC Addresses and Match Them to Window Device Names.

Launch the Manage Your Server Program After Windows Setup Completes.

Determine Which Network Data Ports Are Actively Connected to a Network

By using Microsoft’s Network Connections folder, you can visually determine which Sun Blade X6220 Series PCI EM (PCI Express Module) and NEM (Network Express Module) ports are actively connected to a network. To access the Network Connections folder, follow this step:

Click Start -> Settings -> Control Panel-> Network Connections.

The Network Connections folder appears identifying the actively connected data ports.

Confirm Physical Port MAC Addresses and Match Them to Window Device Names

To confirm the MAC addresses of installed NEM and PCI EM ports and to match them to the Windows Device Friendly Names, you will need to open a command prompt and run ipconfig /all.

To open a Windows command prompt and run ipconfig /all follow these steps:

1. Click -> Start -> Run.

The Run dialog box appears.

2. In the Run dialog box, type cmd then click OK.

The cmd.exe DOS window appears.

3. In the cmd.exe DOS window, enter the command: ipconfig /all

The output from the ipconfig /all command identifies the installed NEM and PCI EM ports by the connection name in the order of enumeration.

Note - The output does not necessarily follow an alpha or numeric order. You can customize the connection name in the Network Connections folder for details, see Microsoft’s documentation. The output below illustrates how the Windows operating system, by default, assigns logical names to network interfaces.

Second Ethernet adapter port.
First Ethernet adapter port.

In the sample output:

Ethernet Adapter Local Area Connection is the Windows default logical name (friendly name) assigned to a network interface.

Note that the first Ethernet Adaptor Local Area Connection appears with a null value. This entry identifies the connection-specific DNS suffix (for example, east.sun.com) and the physical MAC address for that port.

Ethernet Adapter Local Area Connection 2 identifies a disconnected media state, a description, and the physical MAC address for that port.

The numeric value following the Windows logical friendly name refers to the network connection number.

Launch the Manage Your Server Program After Windows Setup Completes

To configure network settings after the Windows Server 2003 Setup program completes, you can use the Manage Your Server program. You can access this program at any time as long as you are logged in as Administrator.

To launch Manager Your Server, do the following:

Click Start -> All Programs -> Administrator Tools -> Manager Your Server.

For specific details about how to specify network settings using the Manage Your Server program, see Microsoft’s documentation.
