About the Ethernet diagnostic tests

The Ethernet group of diagnostic tests the functioning of the Ethernet cards that are in your system. The tests range from testing PCI connectivity through data transfer and data registers. The Ethernet diagnostic tests can generate error messages associated with the hardware and software.

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.

Ethernet diagnostic test menu

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

Test no	Test	Description
1	Comprehensive test	Runs all tests in this menu in current mode.
2	PCI-PCI bridge test	Checks the local PCI-PCI bridge chip on a quad card.
3	Status check	Checks card error status.
4	Display Ethernet address	Reads and displays controller device addresses.
5	Software reset test	Verifies the software reset function, checks the SAIL registers after reset, and verifies default values of all internal registers.
7	Interrupt test	Tests the interrupt mechanism. Checks transmit and receive interrupts, as well as timer interrupts.
8	Link integrity test	Verifies external link condition of physical layer (PHY). Requires loopback plug or Ethernet connection.
9	Internal loopback test	Tests data movement between main memory and the Ethernet chip, using on-chip loopback capability.
10	External loopback test [Xtnd]	Extended test mode: Tests card functionality and data movement between memory and Ethernet cable. Requires loopback plug.
11	Mode switch test [Xtnd] (DEC)	Extended test mode: Tests external loopbacks and mode switching between 10Base-T and 100Base-TX on DEC Ethernet cards.
12	Int Phy loop test (Intel)	Tests data movement between main memory and the Ethernet chip on the Intel Ethernet card.
13	Timer test (DEC)	Tests the timer on DEC Ethernet cards.
14	Verify SROM (DEC 21143)	Verifies function of system SROM.
40	Port test (Intel) [Xtnd]	Extended test mode: Tests the Ethernet port on the Intel Ethernet card. Requires a loopback connector.
41	VLAN test (Intel) [Xtnd]	Extended test mode: Tests the VLAN on the Intel Ethernet card. Requires a loopback connector.
71	Show all registers (DEC)	Displays all memory registers on DEC Ethernet cards.
72	Show revision number	Displays the revision number of the Ethernet card.
73	Display SROM [Factory]	Option not available.
90	Ethernet card selection	Enables the selection of a specific Ethernet card in the system.
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.
