The benchmark command and functionality are about to be replaced by an updated version reflecting the current multithreading scheduler and 10GBit interfaces with more precise benchmarking results.
This example shows how to implement a virtual cross-cable which connects two virtual TAP interfaces (Linux only). This setup is implemented by one instance, where the other instance may be used to examine the HW performance using the BalanceNG benchmark command.
The following BalanceNG instance 1 configuration (/etc/bng1.conf) implements the cross cable and sets up the virtual TAP interfaces:
// configuration taken ...
// BalanceNG ...
hostname c_1_crossover
module crossover
interface 1 {
name veth0
access tap
init "ip addr add 10.0.0.1/24 dev veth0; ip link set veth0 up"
}
interface 2 {
name veth1
access tap
init "ip addr add 10.0.0.2/24 dev veth1; ip link set veth1 up"
}
register interfaces 1,2
enable interfaces 1,2
// end of configuration
