Hi,

There is no way to get the LiSA kernel module to generate a random MAC
address, but you can manually assign a specific (and distinct, of
course) MAC address on each node.

To do this, you need to configure a kernel module option by adding a
line to /etc/modprobe.conf (or to /etc/modprobe.d/lisa.conf, if you are
on a newer distro). The line should look like this:

options switch vif_mac=02:00:11:22:33:44

Then restart LiSA using /etc/init.d/lisa restart.

Please let me know if this solves your problem.

Cheers,

Radu
