Handling Procedure
4. If the PCIe device is visible in
the system but the network
port is invisible, the driver fails
to be loaded. In this case,
perform the following steps:
a. Run the ifconfig eth
command in Linux (or
equivalent in other
operating systems) to
ensure the information in
the network port
configuration file is
consistent with the actual
physical network ports and
whether the network ports
are up.
b. If an error is reported when
you install the driver in
compilation mode, run the
gcc -v and c++ -v
commands on the OS CLI. If
the command output
displays the corresponding
version information, the
GCC and C/C++ software is
installed properly.
Otherwise, install the GCC
and C/C++ software first.
c. Check the optical module
type. If an Intel NIC and a
non-Intel optical module
are configured, the driver
cannot be loaded and the
network port is invisible.
d. Reinstall the driver. Check
that no errors are reported
during the driver
installation and check
whether system logs record
any failures when loading
driver.
5. Collect OS logs. For details, see
