there are no limits in the script, and it should ignore unknown MAC <br>
addresses. Usually problems like this are caused by not configuring the <br>
interface type correctly in IXP Manager (Switches / Switch Ports).<br>
<br>
You can see what's happening in this script by using the "--debug" CLI <br>
parameter.<br>
<br>
Normally we would recommend having dedicated hardware for an IXP.<br>
