By default, emulated models have one Ethernet device. Depending on the model, more Ethernet devices can be added.
The emulated network devices
DE 500 PCI based cards (for 64-bit systems), and
LASI-82596 cards (for the 32-bit system)
do not support Jumbo frames. For physical interfaces, this feature must be disabled in the emulator configuration (together with any other offloading parameters).
Basic Configuration Components

The variable IFACE is set automatically by the emulator upon start.
Supplemental Information: Virtual Bridge and TAP Interfaces
The following example shows a simple example of how to create a virtual bridge on Linux and how to add TAP interfaces to it.
Example using ip commands:
| Step | Command |
|---|---|
| |
ip link set my_tap0 up | |
ip link add name my_bridge type bridge | |
ip link set my_bridge up | |
ip link set <physical-int> master my_bridge | |
ip addr delete <ip-address>/<netmask> dev <physical-int> | |
ip addr add <ip-address>/<netmask> dev my_bridge | |
ip link set my_tap0 master my_bridge |
