PF is not really intended to manage your production DHCP. You need to
provide your own DHCP arrangements for each of your production networks
in a VLAN-switching setup. PF tells the switch to change the client's
VLAN, and that's where PF's responsibility ends.
If you would like to take advantage of PF's IP address history function
(not as great in V4 as it was in V3 IMO), then you will need to use a
Cisco DHCP helper to send those requests to PF IN ADDITION TO your
production DHCP server. You could set up PF interfaces on every VLAN
and let PF listen for the DHCP broadcasts directly, but that really
isn't practical on larger networks...

Subject: [PacketFence-users] DHCP on switch via DHCP helper
Hello listmates,
Let us say I have a PF and I have a number of Cisco switches directly
accessible via IP and I want VLAN's on those switches to be DHCP-managed with
the PF server serving the addresses. How do I do that? Or is that the correct
way to do that?
So continuing on with the example: let us say my PF server is at 192.168.10.5
and a switch sw1 is at 192.168.10.20. sw1 is allocating/serving a number of
VLAN's not even accessible to the PF server. Can it still control them -
including the DHCP on them?
Thanks.
Boris.
