IIRC, this isn't really a function of the DHCP server but of the 
switches and routers in the middle. From my limited knowledge from the 
Harold B Lee Library system, Altirus has a regular DHCP server in it 
serving up requests. The switches and routers in the middle actually get 
a lease from the campus DHCP server and tag on the extra information 
from a lease from the Altirus server. I can't remember what the function 
in the switches was. My recommendation to check and see if this is the 
case would be Dan Wells in OIT or Jonathan Mecham in the Library. I 
might be completely off here though. I didn't really build that system.
