General Description

 The diagnostic program for the dual token-ring interface card includes the following groups of tests:

Figure 9-1 illustrates the menu flow for the dual token-ring diagnostic program. For information on error logging and error statistics, refer to Chapter 2.

Port Configuration

You can configure ports 0 and 1 differently for certain tests. If this is the case, the applicable port number appears above the prompt. When a port number does not appear above the prompt, your entry applies to both ports.

Figure 9¯1 Dual Token-Ring Diagnostic Menu Flow

Executing the Diagnostic Program

To run the dual token-ring diagnostic program, boot the router diagnostic program. Chapter 1 provides the boot procedure.

Once the router diagnostic program boots, the screen displays the Mode Menu. Select the Use automatic mode of operation option to automatically run all of the diagnostic programs. Or, select the Use manual mode of operation option to run the diagnostic programs individually. Chapter 1 provides additional information on automatic and manual mode.

To display the main menu for the dual token-ring diagnostic program:

1. After the router diagnostic program boots, the console displays the Mode Menu. Select the Use manual mode of operation option and the Main Menu appears.
2. From the Main Menu, select the Execute Diagnostics option. This displays the Diagnostic Execution Menu.
3. If the dual token-ring interface card has been added to the system configuration using the router diagnostic program, it appears as a menu item on the Diagnostic Execution Menu with a number in the parentheses. Enter the menu item number that lists the dual token-ring interface card. The console displays the following message followed by the main menu for the dual token-ring diagnostic program: 
CNX Dual Token Ring Standalone Diagnostic Version #.#


-----------------------------------------------------------------------------------------

Network Tests Group

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

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 Dual Token-Ring Diagnostic Main Menu and select Network Tests Group. Figure 9-30 describes the Network Tests Group Menu and Table 9-1 lists the steps to run the network tests.

Menu Item Function
0. Return to previous menu Displays the previous menu.
1. LAN PORT 0 (Not configured) Tests the transmit and receive functions on LAN port 0. This item displays the LAN Port # (Not Configured) Menu (Figure 9-31).
2. LAN Port 1 (Not configured) Tests the transmit and receive functions on LAN port 1. This item displays the LAN Port # (Not Configured) Menu (Figure 9-31).
3. Execute Test Runs the transmit, receive, and echo tests.
A. Toggle Diagnostic Flags Displays the Router Diagnostic Flow Control Flags Menu.
B. Setup Diagnostic Parameters Displays the Router Diagnostic Parameters Setup Menu.
C. Display Dual Token-Ring Parameters Displays the current token-ring parameters.
D. Display Network Statistics Provides statistics on the network tests. Figure 9-32 shows the Network Test Statistics Screen and Chapter 10 defines the statistics.
E. Clear Network Statistics Resets the network test status log to zero.

1. Transmit Only Transmits packets to the receive only node.
2. Receive Only Receives packets from the transmit only node.
3. Echo Test Master Node Transmits packets to an echo slave node.
4. Echo Test Slave Node Receives packets from the echo master node. Once it receives the packets, the echo test slave node swaps the packet source and destination addresses and transmits the packets back to the echo master node.
5. Not Configured Indicates that the specified port is not configured to run the transmit, receive, or echo tests.
A. Toggle Diagnostic Flags Displays the Router Diagnostic Flow Control Flags Menu.
B. Setup Diagnostic Parameters Displays the Router Diagnostic Parameters Setup Menu.

Port/Node

 Activity Menu
1. Determine two unique source IP addresses.
2. A and B Enter a source IP address on both ports/nodes. Menu: Network Tests Group Item: Setup Diagnostic Parameters Menu: Router Diagnostic Parameters Setup Item: Set Node IP Address
3. A Set the destination IP address to match the source IP address on port/node B. Menu: Router Diagnostic Parameters Setup Item: Set Destination Node IP Address
4. B Set the destination IP address to match the source IP address on port/node A. Menu: Router Diagnostic Parameters Setup Item: Set Destination Node IP Address
5. A Configure the various test parameters such as the number of packets and their size. Menu: Router Diagnostic Parameters Setup
6. A and B Set the source node address on both ports/nodes. Menu: Setup Token-Ring Parameters Item: Set Source Node Address
7. A Set the destination node address to match the source node address on port/node B. Menu: Setup Token-Ring Parameters Item: Set Destination Node Address
8. B Set the destination node address to match the source node address on port/node A. Menu: Setup Token-Ring Parameters Item: Set Destination Node Address

 Port/Node

 Activity Menu
9. A or B Specify the port that is to transmit the packets for the test. Menu: Network Tests Group Item: LAN Port # (Not Configured) Menu: Lan Port # (Not Configured) Item: Transmit Only
10. A or B Specify the port that is to receive the packets for the test. Menu: Network Tests Group Item: LAN Port # (Not Configured) Menu: Lan Port # (Not
Configured) Item: Receive Only
11. A and B Execute the test. Menu: Network Tests Group Item: Execute Test
12. A Check the number of packets that were transmitted by viewing the "Number of Packets Transmitted by Adapter" statistic. Figure 9-32 shows the Network Test Statistics Screen. Menu: Network Tests Group Item: Show Network Test statistics
13. B Check the number of packets that were received by viewing the "Number of Packets Received by Adapter" statistic. Figure 9-32 shows the Network Test Statistics Screen. Menu: Network Tests Group Item: Show Network Test Statistics
14. A and B The number of packets transmitted and received should match or be comparably close. If a discrepancy exists, view the other network statistics on both nodes to determine if errors occurred during the test. If other errors do not exist, run the test again. Contact your representative if the significant discrepancy continues.
