LM and Mikrotik routers

[DGrandes]

Hi! do you want to check on Mikrotik DHCP server lease list either it has specific MAC or not?
If yes, here is the script:

Code:

:local exists [/ip dhcp-server lease find mac-address="78:02:F8:7A:96:01"];

Hi, it works perfectly but it doesn't work for what i whant because dhcp server keep MAC address even if i disconect from the network.
I've seen that ARP lease change DC to C when disconect from network.

Do you know the best option to know conected MAC address to network in real time?

Thanks
