I'm still trying to make it work myself, but I think you have a problem
here. That should be a binary string:
dhcp_identifier = UNHEX(REPLACE('aa:bb:cc:dd:ee:ff', ':', ''))

I found this:

By the way, do you happen to know how to make MySQL log show the
contents of the executed query? My log only shows the prepared format,
even when executing:
Execute SELECT host_id, dhcp_identifier, dhcp_identifier_type,
dhcp4_subnet_id, dhcp6_subnet_id, ipv4_address, hostname,
dhcp4_client_classes, dhcp6_client_classes FROM hosts WHERE
dhcp4_subnet_id = ? AND dhcp_identifier_type = ? AND dhcp_identifier
= ?
