Local Area Network Administration

This section describes how to configure the local area network (LAN) interfaces on your Netra server using the Local Area Network module.

The Netra software will only display information about network interface hardware that is currently attached to the Netra server. (Refer to your Netra hardware installation manual for instructions on adding network interface hardware.)

A network interface consists of three elements: the network port, the network protocol, and the interface definition.

• Network port

The network port provides the physical link between machines that comprise a network. Ports can be built into the Netra server, or they can be provided by SBus or PCI cards in the server. The Netra server supports the following types of network hardware:

• Lance Ethernet

• Fast Ethernet

• Fast Ethernet 100 BASE-T

• Quad Fast Ethernet

• Token Ring

• Fiber Channel (FDDI)

• Network protocol

The network protocol defines the communication that travels over the network. The Netra server supports TCP/IP network protocols. The TCP/IP network protocol suite supports the definition of multiple interfaces for a network hardware port and network protocol.

• Interface Definition

The interface definition is the configuration information that is specific to the Netra server. For example, the Netra server requires host addresses for TCP/IP interfaces.

If no network interface is configured, or if the network interface is improperly configured, the Netra server will have difficulty rebooting.

To Add a Network Interface

You cannot administer the Netra server from a remote client without defining the network interface.

1. From the Main Administration page, under "Network Connection Administration," click Local Area Network.

   The Local Area Network Administration page is displayed with a list of network interface hardware to configure.

2. Click Add a TCP/IP Interface for the required network interface.

   An administration page for the selected interface and protocol is displayed.

3. Complete the form using the information in Table 4-1.

   Table 4-1 Network Interface Administration: TCP/IP

   Option	Description
   Host Name/Address	The host name and address for the network interface. This address should not be on the same network as any other configured interface. Example: 129.144.79.5
   Netmask	The netmask address that determines the network with which the host address is associated. Example: 255.255.255.0

To Modify a Network Interface

1. From the Main Administration page, under "Network Connection Administration," click Local Area Network.

   The Local Area Network Administration page is displayed with a list of network interface hardware to configure.

2. Click Modify a TCP/IP Interface for the required network interface.

   An administration page is displayed with existing configuration information for the selected interface and protocol.

3. Complete the form using the information in Table 4-1.

To Delete a Network Interface

1. From the Main Administration page, under "Network Connection Administration," click Local Area Network.

   The Local Area Network Administration page is displayed with a list of network interfaces to delete.

2. Click Delete for the interface you want to remove, then confirm the operation.
