This group of diagnostics tests the functioning of the Ethernet funtionality of the CNAs that are in your system. This diagnostic test can generate error messages associated with the hardware, software, and user input.
The following table describes the tests in the CNA Ethernet diagnostic menu.
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.
| Test no | Test | Description |
|---|---|---|
1 |
Comprehensive test |
This is a superset of tests 2 through 5 and it will test the adapter's entire Ethernet functions. |
2 |
Reset test |
This test will reset the port of the card to test the hardware port reset function. The port reset function will reset both FC and NIC functions for the port. |
3 |
Interrupt test |
Tests the hardware interrupt mechanism. If there is network traffic going though the hardware, the card will generate the interrupt to inform software to handle it. |
4 |
Internal loopback test |
There are two types of internal loopbacks: PCS and HSS internal loopbacks. In the comprehensive CNA NIC portion, the PCS internal loopback mode is tested and in the stress test, the HSS internal loopback is tested. |
5 |
External loopback test [Xtnd] |
Extended test mode: Tests card Ethernet functionality and data movement between host and Ethernet cable. Requires loopback plug. |
70 |
Display NIC information |
The network information about the card is displayed. |
90 |
CNA card selection |
Enables the selection of a specific CNA 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 this diagnostics menu. |
