I have this configuration in my dhcp server, and i try to give to an  
Ip phone with the string "MTA3308" one of the ip address pool bellow,  
but is not working.
class "pepe" {
match if substring (option vendor-class-identifier, 0, 4) = "MTA3308";
}

subnet 192.168.1.0 netmask 255.255.255.0 {
    pool {
      deny members of "pepe";
      range 192.168.1.100 192.168.1.245;
    }
    pool {
      allow members of "pepe";
      range 192.168.1.46 192.168.1.97;
    }
   Set vendor-string = option vendor-class-identifier;
   option domain-name-servers 192.168.1.1, 10.0.0.1;
   option domain-name "ttt.com";
   option routers 192.168.1.1;
   option broadcast-address 192.168.1.255;
   default-lease-time 86400;
   max-lease-time 100000;
}


In the dhcp lease file i have :

lease 192.168.1.219 {
   starts 2 2007/06/12 22:01:35;
   ends 3 2007/06/13 22:01:35;
   tstp 3 2007/06/13 22:01:35;
   binding state active;
   next binding state free;
   hardware ethernet 00:10:99:01:1d:57;
   uid "\001\000\020\231\001\035W";
   set vendor-string = "MTA3308";
   client-hostname "001099011d57";
}


I have a couple of question here :


In this part "(option vendor-class-identifier, 0, 4)" where i can  
find this two numbers (in red ) ?( tcpdump, manufacture manual ).

Can I use part of the mac address to give a range of ip address ?  
( like give from 192.168.1.10 to 20 to all mac address starting with  
00:15:00 ?)


Thanks.
