Configure dhcp to assign ip addresses based on part of the mac address

[aitaseller]

Hi all,

What I am trying to achieve is to configure debian dhcp server to assign ip addresses based on part of the mac addresses starting with 00:0d:da.

I have the following config:

class "TestSwitch" {
match if substring(option agent.remote-id, 2, 12) = "TestSwitch";
match pick-first-value ( option vendor-class-identifier );
option tftp-server-name "10.60.41.75";
option bootfile-name "10.60.41.75";

}

subnet 10.60.200.0 netmask 255.255.248.0 {
# DHCP Setup for test Residential Ring 2
# --- default gateway
option routers 10.60.207.254;
option subnet-mask 255.255.248.0;
option domain-name-servers 10.57.1.71, 10.57.11.71;
pool {
allow members of "TestSwitch";
range 10.60.200.1 10.60.200.230;
range 10.60.201.1 10.60.201.230;
deny dynamic bootp clients;
}
}

So I was thinking of two solutions. Corret me if I am wrong. I am note sure if the and statement is correct?

The first one is to add a statement under class "TestSwitch":

class "TestSwitch" {
match if ((substring(option agent.remote-id, 2, 12) = "TestSwitch") and (substring (hardware, 1, 3) = 00:0d:da));

subnet 10.60.200.0 netmask 255.255.248.0 {
# DHCP Setup for test Residential Ring 2
# --- default gateway
option routers 10.60.207.254;
option subnet-mask 255.255.248.0;
option domain-name-servers 10.57.1.71, 10.57.11.71;
option domain-name "rg.testmgmt.hef.dk";
pool {
allow members of "TestSwitch";
range 10.60.200.1 10.60.200.230;
range 10.60.201.1 10.60.201.230;
deny dynamic bootp clients;
}
}

The other solution ( I am not sure if I can allow two classes in the allow members ?) is:

class "Test" {
match if substring(hardware, 1, 3) = 00:0d:da;
}

subnet 10.60.200.0 netmask 255.255.248.0 {
# DHCP Setup for test Residential Ring 2
# --- default gateway
option routers 10.60.207.254;
option subnet-mask 255.255.248.0;
option domain-name-servers 10.57.1.71, 10.57.11.71;
option domain-name "rg.testmgmt.hef.dk";
pool {
allow members of "TST1CUPE10";
allow members of "Test";
range 10.60.200.1 10.60.200.230;
range 10.60.201.1 10.60.201.230;
deny dynamic bootp clients;
}
}
