Class declarations are global. Take it out of the subnet declaration. If these two subnets are on the same vlan they should be in a 'shared-network' declaration. The class should also be outside of this shared network.

this somewhere in my googling. I’ve a situation where I have an
option 82 definition for a port on a switch and a separate subnet definition. If
I plug my client into the switch port which has the class definition for a
subnet AND I plug my dhcp server into the switch port next to my client –

of both. Here’s the config file:</span></font></p>
