Cannot find MAC address in scan report

I've performed a discovery scan with Founds 6.5, to get an inventory of all Mac OS devices within the enterprise.  After reviewing the scan report,  I noticed in the Banner column of the report that the MAC address for the devices equals null.  The MAC address shows proper for PCs.  Any ideas on this?

Re: Cannot find MAC address in scan report

MVM can only discover the MAC address of Windows based systems. We do this by doing a banner grab on TCP port 137, which is the Windows netbios port.

Since ARP requests will not pass through a router unless configured to do so this is the only reliable method.

does this still hold true?  i have the most up to date defs but mvm still cannot find the MAC address of any of my *nix machines.
