omdiag: Using the Diagnostic Service 29
omdiag chassis network
Use the omdiag chassis network command to test the NIC. Three main categories of diagnostic tests
available are:
• Generic Network Diagnostic Tests
• Broadcom NIC Diagnostic Tests
• Intel

NIC Diagnostic Tests
Generic Network Diagnostic Tests
The following two tests are available on all Dell™ supported NICs:
– NIC Communication Test — Checks whether the NIC under test is physically connected (wired)
to the network. It also checks whether the NIC has a valid IP address.
NOTE: The network team test is only available on systems running a supported Microsoft Windows
operating system.
– NIC Team Test — Checks whether the NIC under test is in team mode. NIC teaming is one
method for providing high availability and fault tolerance in systems.
Broadcom NIC Diagnostic Tests
The following tests are available on Dell supported Broadcom NICs:
– BRCMNetwork Control Registers Test — Tests most of the internal registers on the chip. Each
chip contains many internal registers. Each register can contain some read-only bits and some
read/write bits. This diagnostic tests read-only bits that cannot be overwritten, and tests if
read/write bits can be written properly.
– BRCMNetwork MII Registers Test — Tests most MII registers on the chip. Each chip contains
many MII registers. Each MII register may contain some read-only bits and some read/write bits.
This diagnostic tests read-only bits that cannot be overwritten, and tests if read/write bits can be
written properly.
– BRCMNetwork EEPROM Test — Tests the EEPROM checksum of the bootstrap record and the
configuration block on the chip.
– BRCMNetwork Internal Memory Test — Tests most of the internal memory of the chip. Each chip
contains a certain amount of on-chip memory to support on-chip processor operations.
– BRCMNetwork Interrupt Test — Tests the interrupt capability of the chip by verifying that the
NDIS driver is able to receive interrupts from the NIC.
– BRCMNetwork MAC Loop–back Test — Verifies that the NDIS driver is able to send and receive
packets from the NIC. It issues IOCTL (Input Output Controls) to request driver setup
(MAC layer loop back) in hardware.
– BRCMNetwork PHY Loop–back Test — Verifies that the NDIS driver is able to send and receive
packets from the NIC. It issues IOCTL (Input Output Controls) to request driver setup
(PHY layer loop back) in hardware.
