26 omdiag: Using the Diagnostic Service
NOTE: The following tests are only available on systems running a supported Microsoft Windows operating system.
– Intel Control Registers Test — Checks for any conflicts in the I/O address and tests the
accessibility of the registers. This test includes all General Registers, Receive Registers, and
Transmit Registers. It does not test the EEPROM Control/Data Register.
– Intel EEPROM Test — Verifies the integrity of data read from the EEPROM. This test completes a
write and read from the EEPROM and then compares the results for consistency.
– Intel Interrupt Test — Uses the Interrupt registers to confirm that all NIC interrupts work.
– Intel MAC Loopback Test — Tests the NIC’s ability to send and receive packets by sending packets to
itself. This test uses the MAC Loopback mode.
NOTE: The Intel MAC Loopback Test is not supported on the Intel PRO/1000 MF and the Intel PRO/1000 MT DP
network cards.
– Intel PHY Loopback Test — Tests the NIC’s ability to send and receive packets by sending packets
to itself. This test uses the PHY Loopback mode. Not all NICs support PHY Loopback.
– Intel Link Test — Checks the network connection, and the NICs send and receive functionality by
sending 1000 proprietary packets out on the network and retrieving those same packets.
The Intel Online Diagnostics tests and the Intel Offline Diagnostics tests are only available on systems
running a supported Red Hat Enterprise Linux operating system.
– Intel Online Diagnostics Tests — Performs a limited set of tests without interrupting normal NIC
operation during the tests.
– Intel Offline Diagnostics Tests — Performs a full set of tests. This test might disrupt the normal
operation of the NIC.
omdiag chassis parallelport
Use the omdiag chassis parallelport command to test the parallel port, which is a high-speed
communications port for attaching certain devices to your system.
The parallel port test writes a series of characters to the port and then reads it back again. If this test
detects differences between the written and read character series it logs an error message and the test
fails. The parallel port test performs the following tests:
• Mode Test — Tests the different modes of the Extended Capabilities Port (ECP). The following
modes are tested:
– Standard Mode (unidirectional)
– Byte Mode (a bi-directional mode, also called Reverse Mode)
– Parallel Port FIFO Mode (SPP hardware-handshake)
– EPP Mode (may not be available depending on chipset)
– ECP FIFO Mode (ECP hardware-handshake)
