Thank you for the information.
Tha problem is, that i have to migrate some dhcp-server from 3.0.5 to 4.1.0,
and the configs are pretty old and from another guy, who leaves our company.
After several test, i stumbled over the problem with the class-match and
the known statement. Thatswhy i asked the question and got some really
useful information from you.

Best Regards,
