Hi.

For some machines "Tools-> info-> ARP cache (SNMP)" option return mac-address from cache all like  00:00:00:00:00:00.

I think NetXMS use 1.3.6.1.2.1.3.1 OID instead 1.3.6.1.2.1.4.22.1.2

Description
The Address Translation tables contain the NetworkAddress to `physical' address equivalences. Some interfaces do not use translation tables for determining address equivalences (e.g., DDN-X.25 has an algorithmic method); if all interfaces are of this type, then the Address Translation table is empty, i.e., has zero entries.

Best regards.

Hi!

You can try to create custom tool for 1.3.6.1.2.1.4.22.1.2. I'm not sure that all devices supports IP-MIB, so changing default tool to it may not be a good idea. Probably another standard tool based on IP-MIB should be added.

Best regards,
