Network Test Group

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

You can run the network tests on any of the four ports on the quad serial card. Any port can be configured to transmit or receive the packets during the tests. You can also use two nodes to run the network tests: a transmit node and a receive node. The receive node must reside on the same subnet as the 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 destination address of the router running diagnostics should match the node IP source address of the operational node.
If you are running the network tests on two nodes, the receive node does not have to be executing diagnostics. 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. Boot the router that is running the diagnostics via the operational node. Chapter 1 provides the boot procedure.

4. From the router that is running diagnostics, display the Quad Serial Line Diagnostic Main Menu and select Network Tests Group. Figure 8-13 describes the Network Test Group Menu and Table 8-1 lists the steps to run the network tests.
