Network Tests Group

This group tests the transmit, receive, and echoing functions of the FDDI interface card when it is connected to a network. Before you run the network tests, note the following:

The network tests require two nodes: a transmit node and a receive node.
The receive node must reside on the same subnet as a transmit node.
If the tests are running on a network with active routers, do not use default addresses. If the network is only running diagnostics, you can use the default addresses.
The node IP and physical destination addresses of the router running the diagnostics should match the node IP and physical source addresses of the operational node.
The receive node does not have to be executing diagnostics during the network tests. It can be a router supporting IP. However, the Address Resolution Protocol (ARP) table must be manually configured to set the node IP destination address. To configure the Arp table:

1. Select an operational node for testing.

2. Set the ARP timers to zero so that the ARP cache does not expire. At the operational node, enter set refresh-timer 0 after the ARP config> prompt. For further information on configuring ARP, refer to the Bridging Router Protocol Configuration Guide, Volume 1.

3. Via the operational node, boot the router that is running diagnostics. Chapter 1 provides the boot procedure.

4. From the router that is running diagnostics, display the FDDI Diagnostic Main Menu and select Network Tests Group. Figure 6-22 describes the Network Tests Menu and Table 6-1 lists the steps to run the network tests.
