Question regarding client classes

Ick, I mistakenly sent this to dhcp-hackers; I humbly apologise.
List,
I have a number of similar clients (phones) with the same vendor-id, but they
exist on different subnets.
How can I best set subnet-specific options for these classes?
I thought I would be able to define a bunch of "class" defines:
class "Phones-Subnet1" {
match if substring (option vendor-class-identifier, 0, 3) = "SOFT";
option soft-option "ip1=10.0.0.1;ip2=10.0.0.2;";
}
class "Phones-Subnet2" {
match if substring (option vendor-class-identifier, 0, 3) = "SOFT";
option soft-option "ip1=10.1.0.1;ip2=10.1.0.2;";
}
class "Phones-Subnet3" {
match if substring (option vendor-class-identifier, 0, 3) = "SOFT";
option soft-option "ip1=10.2.0.1;ip2=10.2.0.2;";
}
and then use a number of "shared-network" definitions, so:
shared-network "subnet1" {
subnet 10.0.0.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option routers 10.0.0.254;
default-lease-time 28800;
max-lease-time 86400;
pool {
range 10.0.0.64 10.0.0.128;
allow members of "Phones-Subnet1";
}
}
}
shared-network "subnet2" {
subnet 10.1.0.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option routers 10.0.0.254;
default-lease-time 28800;
max-lease-time 86400;
pool {
range 10.1.0.64 10.1.0.128;
allow members of "Phones-Subnet2";
}
}
}
shared-network "subnet3" {
subnet 10.2.0.0 netmask 255.255.255.0 {
option subnet-mask 255.255.255.0;
option routers 10.2.0.254;
default-lease-time 28800;
max-lease-time 86400;
pool {
range 10.2.0.64 10.2.0.128;
allow members of "Phones-Subnet3";
}
}
}
However, this does not appear to work (perhaps I missed something important
in the documentation ..); all networks are given options from the
Phones-Subnet1 class (I guess, first match ..).
What would the best work-around be?
Kind regards,
Tor
