About the FDDI diagnostic tests

The FDDI group of diagnostic tests the functioning of the FDDI cards that are in your system. The tests range from a status check of the card through the testing of data movement through the system while the FDDI card is being used. The FDDI diagnostic tests can generate error messages associated with the hardware.

Note: Tests that are labeled [Xtnd] often require loopback plugs for complete test operation and will indicate failures without these plugs.

Caution: Do not run [Xtnd] mode diagnostics on network adapter cards with live network connections. Disconnect all network connections prior to running network diagnostics in [Xtnd] mode. Running with attached networks can adversely affect other attached devices. Type xtnd n to cancel Extended test mode.

FDDI diagnostic test menu

The following table describes the tests in the FDDI diagnostic menu.

Test no	Test	Description
1	Comprehensive test	Runs all tests in this menu in current mode.
2	Status check	Checks card error status.
3	Display network address	Reads and displays card device.
4	Display SMT information	Checks and displays SMT information, such as media type.
5	Internal loop test	Tests data movement between main memory and the FDDI controller, using onboard loopback capability.
6	External loop test [Xtnd]	Extended test mode: Tests FDDI controller functionality and data movement between memory and FDDI cable. Requires loopback plug.
71	Show PDQ revision	Displays PDQ revision of the card.
72	Show firmware revision	Displays the firmware running on the card.
91	Enable/disable looping	Enables or disables continuous running of a diagnostic test. The test is stopped when Ctrl-C is pressed or when an error is encountered if option 92 is active.
92	Stop/continue on error	Starts or stops running a diagnostic test on an error. If looping is enabled, as set by option 91, looping continues after an error is encountered.
93	Extended/normal test mode	Enables or disables extended mode on tests where extended mode is an available option.
99	Exit	Exits diagnostics.
