</div>Hi,<br>
<br>
There is no way to get the LiSA kernel module to generate a random MAC<br>
address, but you can manually assign a specific (and distinct, of<br>
course) MAC address on each node.<br>
<br>
To do this, you need to configure a kernel module option by adding a<br>
line to /etc/modprobe.conf (or to /etc/modprobe.d/lisa.conf, if you are<br>
on a newer distro). The line should look like this:<br>
<br>
options switch vif_mac=02:00:11:22:33:44<br>
<br>
Then restart LiSA using /etc/init.d/lisa restart.<br>
<br>
Please let me know if this solves your problem.<br>
<br>
Cheers,<br>
<br>
