2.10 Installing Networking Protocols

NetWare can process IP (Internet Protocol) network packets and traditional IPX (Internetwork Packet Exchange™) packets. Both protocols can be assigned to a single network board, which allows the server to communicate using IP and IPX.

2.10.1 About the Internet Protocol (IP)

The Internet protocol (IP) lets your network share data with other IP networks, including the Internet. Using IP requires a unique IP address, a subnet, and a router or gateway address.

  • IP Address: Identifies each device on the network. The address consists of 32 bits, which are represented as decimal values separated by periods, such as 123.45.67.89.

    If your server will connect to the Internet, you must obtain a unique IP address. For information on receiving an IP address, contact your Internet service provider (ISP).

  • Subnet Mask: Lets you break up your network into smaller networks. Your network might have too many nodes or might be too geographically dispersed to manage as a single network.

    Dividing your network into smaller networks allows the network routers to filter and reduce the network activity seen by any of the nodes. However, dividing your network and using several network addresses might not be appropriate on a large network that needs to appear to network administrators as a single network.

  • Router (Gateway): The address of the router that connects two different environments, such as a LAN and the Internet.

    You can specify a specific router (gateway) address or you can rely on the network to automatically find the nearest router. If you specify the address, remember that the router must exist on your network segment.

Installing IP will automatically bind to the Ethernet_II frame type.

When IP is selected, passive support for IPX is also provided to support IPX-based applications without binding IPX. If an IPX request arrives at the server, OES NetWare will process the IPX request. This passive support for IPX is called Compatibility Mode and is automatically enabled to provide service for applications that require IPX.

HINT:You can disable Compatibility Mode by removing the LOAD SCMD command from the server’s autoexec.ncf file. When IPX Compatibility Mode is disabled, the server will process only IP packets. Applications that require IPX will not function properly.

2.10.2 About IPX

Novell’s traditional protocol, Internetwork Packet Exchange (IPX), lets you continue using IPX-based applications. If IPX, but not IP, is installed on your server, it will actively process IPX packets and ignore packets using other protocols, such as IP.

During the installation program, existing IPX frame types will be detected. The installation program will detect one of the following conditions.

  • A single IPX frame type: If a single frame type is detected, it will be installed.

  • Multiple IPX frame types: If detected, you will be prompted to choose the frame types that you want to install.

  • No IPX frame types: If no frame types are detected, Ethernet_802.2 will be installed by default.

2.10.3 Using Both IP and IPX

If you have network clients or applications that require IPX and IP, you can install both protocols. Both protocols can be bound to a single network board. When selected, both IP and IPX protocols are actively supported. The server will process IP requests using IP, and it will broadcast and reply to IPX requests using IPX.

2.10.4 Installing IP and IPX

  1. From the Protocols page, select a network board.

  2. Select the IP check box.

  3. Type the required IP information for the selected network board.

  4. Select the IPX check box if you are installing IPX on the selected network board.

    If you choose to install IP and not IPX, the SERVERID reference is not used and is removed from autoexec.ncf. You can add IPX after the server installation by adding the SERVERID 8_digit_number command after the SERVERNAME command in autoexec.ncf.

  5. Repeat Step 1 through Step 4 for each network board in the server.

(Optional) Configuring SLP

Service Location Protocol (SLP) is an IETF standard for enabling network-based applications to automatically discover the location, including the address or domain name and other configuration information, of a required service. Using SLP, clients can connect with and make use of services on an IP network. Without SLP, network resources must be manually configured or specified in a separate configuration file.

SLP should be configured properly if the server is going to be a part of a migration using the NetWare Migration Wizard utility from the Server Consolidation and Migration Toolkit.

  1. From the Protocols page, click Advanced.

  2. Select the SLP tab.

  3. Either specify the IP addresses of the Directory Agents on your network or, if no Directory Agents exist on your network, check the Configure This Server as a DA check box.

  4. If you want to enable multicasting, select the Enable Multicast Routing on This Server check box.

  5. Click OK.

(Optional) Configuring SNMP

Network management utilities use Simple Network Management Protocol (SNMP) to record and communicate information about network devices. Using an SNMP-compatible utility, you can set and monitor threshold levels and specific events such as packets per second or error rates. The information is then sent to the destination address of the workstation running the SNMP-compatible management utility.

  1. From the Protocols page, click Advanced.

  2. Select the SNMP tab.

  3. (Optional) Type a hardware description, server location, and administrator in the fields provided.

  4. Type the IPX and IP destination addresses of the devices that will receive the SNMP information in the fields provided.

  5. Click OK.

(Optional) Configuring IPX Compatibility

When enabled, IPX compatibility provides passive support for IPX-based applications without binding IPX. Although the server does not broadcast services using RIP and SAP, NetWare processes any IPX request that arrives at the server.

  1. From the Protocols page, click Advanced.

  2. Select the IPX Compatibility tab.

  3. (Conditional) Select the Load IPX Compatibility check box. This option is only available if you did not select the IPX box in Installing IP and IPX.

    1. Type the eight-digit hexadecimal compatibility mode network number in the field provided or accept the default shown.

    2. Select the preferred IP address from the drop-down list.

  4. (Conditional) Select the Load the Migration Agent on This Server check box. This option is only available if you checked the IPX box in Installing IP and IPX.

    NetWare regulates IP and IPX protocols using a Migration Agent. A Migration Agent regulates the protocol function on different network segments. If a Migration Agent is not enabled, packets are not forwarded onto network segments communicating with a different protocol. For more information, see the online help file associated with this screen.

    1. Type the eight-digit hexadecimal compatibility mode network number in the field provided or accept the default shown.

    2. Select the preferred IP address from the drop-down list.

  5. Click OK.

    After completing the previous optional steps, you are taken back to the Protocols page.

  6. Click Next.
