Basic Configuration Components

Ethernet Interface Names

Names on 64-bit systems:

The name of the Ethernet interface in the emulator configuration file has the format EWxn with the following definitions:

• x is an upercase letter starting with A for the first interface and then continues with B, C, etc. for additional interfaces. The possible number of network cards depends on the features of the original physical system. The absolute maximum number is 16.
• n is the device number of the card starting with 0 for each value of x.

Names on 32-bit systems:

The currently supported 32-bit system supports only one Ethernet card named system.lan0.card.

Minimal Configuration Parameters

The configuration of each network interface must at least have two basic components (shown for as shown below:

64-bit system (example shows the first Ethernet card EWA0):

• Interface definition (EWA0.iface)
• Interface initialization command: (EWA0.initialize_command)

32-bit system:

• Interface definition (system.lan0.card.iface)
• Interface initialization command: (system.lan0.card.initialize_command)

The default configuration assumes that a physical network interface will be used.

Please refer to the Configuration File Reference and the configuration template of your model for more information.

Basic Configuration Example

Example of a basic network card configuration using a physical interface on a 64-bit emulated system:

EWA0.iface="enp0s20f0u3u4"
EWA0.initialize_command="ethtool -K ${IFACE} rx off ; ethtool -K ${IFACE} tx off ; ethtool -K ${IFACE} sg off ; ethtool -K ${IFACE} gso off ; ethtool -K ${IFACE} gro off ; ethtool -K ${IFACE} txvlan off ; ethtool -K ${IFACE} rxvlan off"

The variable IFACE is set automatically by the emulator upon start.Please refer to the Configuration File Reference and the configuration template of your model for more information.
