Configuring SPX Connection Parameters

Because some Novell and third-party NetWare applications place unique demands on the SPX transport protocol, NIASCFG enables you to adjust the values of the following parameters:

• Maximum IPX Socket Table Size ---Maximum number of concurrent IPX sockets that can be opened by an application.
• SPX Watchdog Abort Timeout ---Time, in ticks (about 1/18 of a second), SPX waits without receiving a packet from the other end of a connection before concluding that the connection is no longer valid.
• SPX Watchdog Verify Timeout ---Time, in ticks, SPX waits without receiving a packet from the other end of a connection before requesting a watchdog, or keep-alive, packet.
• SPX Ack Wait Timeout ---Time, in ticks, SPX waits without receiving an acknowledgment for a data packet it sent, before resending the packet.
• SPX Default Retry Count ---Number of times SPX resends a data packet if it does not receive an acknowledgment.

  The product of this parameter and the SPX Ack Wait Timeout is about how long it takes for SPX to conclude that the connection is no longer valid.

• Maximum Concurrent SPX Sessions ---Maximum number of concurrent SPX sessions that can be opened by an application program.

The default values for these parameters are sufficient for most NetWare applications. Any application that requires a change to one or more of these parameters typically tells you so.

How to Configure SPX Connection Parameters

To adjust the value of any SPX connection parameter, complete the following steps:

1. Load NIASCFG, then select the following parameter path:

   Select Configure NIAS > Protocols and Routing > Protocols > IPX > IPX/SPX Parameters

   The IPX/SPX^TM Parameters menu displays the SPX connection parameters.

2. Enter a new value for each parameter you need to change.

3. Press Esc and save your changes.

4. Press Esc to return to the Internetworking Configuration menu.

5. If you want this change to take effect immediately, select Reinitialize System .

   If you want to configure other parameters, do so now, then reinitialize the system when you are finished.
