Allows you to query or change the settings of an Ethernet device (a network interface device, sometimes referred to as a NIC, or Network Interface Card). Use ethtool to view or change the settings of the network interfaces on the AE Services server. When you use ethtool to change the network interface settings, the changed settings will not persist after rebooting the AE Services server. To specify new persistent settings for the network connection, you must use the AE Services Management Console. For more information about changing network settings, see Editing the NIC configuration (optional).
The following list provides examples of using the ethtool command for AE Services.
ethtool eth0
Displays the settings of eth0.
ethtool -s eth0 autoneg on
Turns on auto-negotiation for eth0. This is the default setting for any interface unless it is changed.
ethtool -s eth0 autoneg off
Turns off auto-negotiation for eth0. When you want to change the settings of a network interface, such as the network speed or the duplex mode, you must turn off auto-negotiation first.
ethtool -s eth0 speed 100
Sets the network speed of eth0 to 100 Mbs. This is the required speed for AE Services.
ethtool -s eth0 duplex full
Sets the duplex mode to full for eth0. This is the required duplex mode for AE Services.
ethtool -s eth0 speed 100 duplex full
Sets the network speed and duplex mode for eth0 with a single command entry.
