Different hardware options based on subnet

[Ricardo Stella]

Not a newby but definitely beginner in terms of experience here.

In our dhcpd.conf file we have a class set up to identify IP phones and we
assign the server they need to connect to:

class "i2004-clients" {
        match if substring (option vendor-class-identifier, 0, 14) =
        "Nortel-i2004-A";
        option nortel-specific-info =
        "Nortel-i2004-A,10.1.0.10:4100,1,15;10.1.0.10:4100,1,15.";
        option vendor-class-identifier "Nortel-i2004-A";
}

In a subnet, I have the following, which works perfectly fine.

        subnet 10.10.0.0 netmask 255.255.0.0 {
          authoritative;
          option routers 10.10.0.1;
          one-lease-per-client true;
          pool {
            allow members of "i2004-clients";
            range 10.10.250.50 10.10.250.249;
            max-lease-time 43200;
            default-lease-time 43200;
          }

There's other pools as well, and we have several other vlans like the above
and all IP phones get the default configuration.

But I need to assign some phones to a different controller - that is I need
to assign those that land in this specific vlan with the following:
          option nortel-specific-info =
          "Nortel-i2004-A,10.2.0.10:4100,1,15;10.2.0.10:4100,1,15.";

I tried creating a different class, but because hardware is the same, they
fall under the first defined one. I tried adding the above inside the pool
section but they still get the globally defined one. Am I missing
something? Or would I need to assign the class or the above lines to every
vlan and take it out of the global config?

Thanks in advance - Ricardo.
