assigning groups to classes

[Victor Hiebert]

Trying to assign specific ranges to specific groups, it seems the way to do this is with classes.  Would like the assignment to happen without relying on input from the clients, eg not vendor-class-identifier.  Also I MUST use groups, and can't simply define specific clients within a class.

It looks like the config-option expression is what I want, I take this expression to mean that if a client would be handed the option from the dhcpd.conf then it will be placed in the specified class.  However this never seems to work, perhaps I'm simply misunderstanding how classes and/or the config-option work?  Example dhcpd.conf below showing attempted group assignment to a class based on the domain-name option.

### begin dhcpd.conf

class "groupofcomputers" {
match if (config-option domain-name = "group.of.computers.com");
}

group {
	option domain-name "group.of.computers.com";

	host host1 {
                hardware ethernet 00:0c:29:f4:40:c8;
        }
        host host2 {
                hardware ethernet 00:15:17:63:17:0b;
	}
}

subnet 10.0.0.0 netmask 255.255.255.0 {
        option broadcast-address 10.0.0.255;
        option subnet-mask 255.255.255.0;

	pool {
                allow members of "groupofcomputers";
                range 10.0.0.2 10.0.0.10;
        }
}

### end dhcpd.conf
