I've got a couple of switches (non-Mikrotik) of different vendors that, as a function of their DHCP Snooping implementation, show what IP address has been assigned to devices on each port. I cannot seem to locate this information in Mikrotik RouterOS - is this not part of their implementation? Alternately, I tried to locate the MAC address that had the lease for the IP address I was looking for, but it only showed up on the bridge itself - I had to torch each interface until I found the IP address. Any ideas? I am using VLANs on each port, assigned to two different bridges.

Your port/interface to the CPU with the DHCP server is the bridge (, or other nonbridged interfaces). From there it splits further and further, irrelevant for the DHCP server. If you want to follow where it is going, look in the bridge "Hosts" table , and in other switches "MAC table".
