Nir,
We have to use special settings in DHCP to use the UUID. It requires
the ISC DHCP server v3.0. Here's what the dhcpd.conf looks like:
class "c6.cluster4" { #CSM CLASS FOR c6.cluster4
match if substring(option client-guid,1,16) =
be:57:32:c6:e8:1d:b2:11:8d:f3:ca:8c:18:95:4f:29;
}
pool { #CSM POOL FOR c6.cluster4
allow members of "c6.cluster4";
range 10.64.40.6;
option domain-name "cluster4";
option host-name "c6.cluster4";
option routers 10.64.0.1;
}
This allows us to bind the UUID to IP, and then pxelinux branches based
on the IP...
