Netra Proxy Cache Array User's Manual

Chapter 8 Local Area Network Administration

This chapter describes how to configure the local area network (LAN) interfaces on the Netra Proxy Cache Server using the Local Area Network module.

Local Area Network Requirements

A network interface consists of three elements:

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 PCI cards in the server. The Netra server supports Fast Ethernet 100 BASE-T (hme).

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

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.

LAN Procedures

The Netra server cannot be administered from a remote client without first defining the network interface.

Note -

It is strongly recommended that you not make any changes to the service network (hme0) or control network (hme1) interfaces. If you do make changes to these interfaces, make them in the Proxy Cache Administration page. Such changes are reflected in the Local Area Network Administration page. If you make any changes to the service network (hme0) or control network (hme1) interfaces in the LAN Administration page, you must make corresponding changes to your array and array member configuration in the Proxy Cache Administration page.

Adding a Network Interface

To Add a Network Interface

  1. Choose Network Connection Administration: Local Area Network.

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

  2. Choose Add a TCP/IP Interface.

    An administration page for the TCP/IP interface is displayed.

  3. Type the information in the form using Table 8-1.

    Table 8-1 Information Required to Add an Interface

    Host Address/ 

    Host Name 

    The host address or host name for the network interface.  

    This address should not be on the same network as any other configured interface. Example: 129.144.79.5  

    The host name is valid if it has been entered in the local name service. See Chapter 9, Name Service Administration," for more information.

    Netmask 

    The netmask address that determines the network with which the host address is associated. Example: 255.255.255.0 

Modify a Network Interface

To Modify a Network Interface

  1. Choose Network Connection Administration: Local Area Network.

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

  2. Choose Modify a TCP/IP Interface.

    An administration page is displayed with existing configuration information for the chosen interface.

  3. Make the changes in the form using Table 8-1.

Delete a Network Interface

To Delete a Network Interface

  1. Choose Network Connection Administration: Local Area Network.

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

  2. Choose Delete for the interface to be removed; then confirm the operation.

    Note -

    If you remove the interface by which your browser is connected to the server, you can longer perform administrative procedures. If the server has other network interfaces through which you can use your browser to connect to the server, you can use such an interface to continue administration of the machine. If there are no remaining interfaces, you lose the ability to connect using a browser and have to rely on a serial connection, as described in Appendix A of the Netra Proxy Cache Server Configuration Guide or Netra Proxy Cache Array Configuration Guide.
