Detect Multiple MacAddress in the interface?

[doki]

Hi,

How can netxms detect multiple mac address on the interface ? (not on uplink or bridge aggregate) . The reason i ask because most of our users bring cheap network hub/switch inside the campus. LLDP, CPD, FDB etc. wont able to detect this as switch or any network device. So if i can detect multiple mac address in the edge switch interface its more likely its a hub or switch.

Thanks,
Doki

Yes, NetXMS will correctly detect multiple MACs on ports, and will know there is an un-managed switch behind your normal managed switch on port x.

How? Can you help enlighten me? thanks!

I found the data I needed on topology > Switch Forwarding Database (Mac Address Table) now what I need is how can I use these data into an event? Example, If multiple macs found on the particular interface. it will generate an alert.

Hi,

currently there is no way to get FDB information into DCIs. I can add a function to read FDB entries for node in next release, then you'll be able to create scripting DCI or poller hook to control it.

Best regards,
