Network Connectivity Testing for Linux
To verify that the Ethernet interface is up and running, run
ifconfig
to check the
status of the Ethernet interface. Use
netstat -i
to check the statistics on the
Ethernet interface.
Ping an IP host on the network to verify that the connection has been
established.From the command line, type
ping < ip_address >
, and then press
ENTER. The ping statistics that are displayed indicate whether or not the network
connection is working.
The adapter link speed can be forced to 10Gbps or 25Gbps using the operating
systems GUI tool, or the ethtool command,
ethtool –s ethX speed SSSS

Microsoft Virtualization with Hyper-V

2012 R2. For more information on Hyper-V, see

Linux
Problem : QL45212 devices with SFP+ Flow Control default to Off rather than
Rx/Tx Enable.
Solution : The Flow Control default setting for revision 1.6. x and newer has been
changed to Rx Off and Tx Off because SFP+ devices do not support
auto-negotiation for Flow Control.
Problem : Errors appear when compiling driver source code.
Solution : Some installations of Linux distributions do not install the development
tools by default. Ensure the development tools for the Linux distribution you are
using are installed before compiling driver source code.
