3: Operating the Adapter
Changing the Configuration
Configuration changes for Ethernet devices drivers are made by means of the
ethtool(8) command. The ethtool command works with all Linux Ethernet drivers.
In general, each feature has a query and a modify variant. If you are wondering
whether the current driver and ethtool support a specific feature, attempt to run the
query option first, an example is, as follows:
# ethtool -a eth0
Pause parameters for eth0:
Autonegotiate: on
RX: on
TX: on
This shows the current settings of the pause (or flow control) parameters. You can then
change these parameters with the ethtool -A option.
As with any system configuration changes, make sure to have a back out strategy, read
the most recent documentation for potential changes and pitfalls, and consult with a
relevant Linux archives for examples of common usage.
Troubleshooting
The following standard Linux commands are useful with any Ethernet device:
• ethtool(8)
• ifconfig(8)
• ip(8)
For more information, see the man page associated with each tool.
