Hi,
have the same with at least one wifi connected device. Devices are BYOD, so I have no client device information or access to its settings.
The setup is with 2 hAP ax3 with ROS 7.12 , with each having a DHCP server per VLAN serving the same subnets, but with non-overlapping address pools. (split scope)
Clients should stick with one DHCP server for renewal, once served by one of the DHCP servers. The other DHCP server should not NACK the address if not in his pool.
Fact is that that client constantly flips between the 2 DHCP servers.

Setting one of the 2 ax3 DHCP server sides with [Authoritative "after 10 seconds delay"] and removing its list with Leases , this completely stopped the flipping.
Well actually now all leases are now on the other ax3 set of DHCP servers.
Internet readings .... exclusion ranges in MT ???
IPAM 2020.2
CAUSE
The IP conflict is caused by both DHCP servers managing the same IP and issuing lease information to them. In a correctly configured split scope, two DHCP servers setup scopes within the same subnet. Once that scope is setup however, each DHCP server must set an exclusion range that is the opposite of the other DHCP server within that range.
