Hardware dependant Static DHCP

[Laurent CARON <lcaron@unix-scripts.info>]

Hi,

I'm basically trying to set-up the following thing.

A DHCP server serving my computers on one range (say: 192.168.0.10 - 
192.168.0.100), and i'd like to give IP addresses in the range 
(192.168.0.110 - 192.168.0.200) to my IP phones (Polycom IP600).

I already tried to get the vendor string by adding
set vendor-string = option vendor-class-identifier;
in the dhcpd.conf but without success (nothing useful appears in the 
leases file for that phone).

Do you know a good way to achieve my goal ?

Thanks

Laurent
