Jake, Thanks for the reply. It is seeing the port up/down. I'm about to do a packet cap to make sure that it's sending DHCPREQUEST, but I have no reason to suspect it isn't - I think that it sends the request but dhcpd on the PF box never see's it.

Subject: Re: [Packetfence-users] Fwd: VLAN assignment and DHCP Check to make sure the client is seeing the port go down, I have seen in windows if the port goes down and comes back too fast the client will not notice the change and will not arp for a new dhcp address.

Subject: Re: [Packetfence-users] Fwd: VLAN assignment and DHCP Yes, my production DHCP server will handle IP addresses for the production network. There is no overlapping of scopes at all. Reg and Iso vlans are handled by dhcpd on pf box Production networks are handled by dhcp on a separate server. I have interfaces with a dhcplistener running on them so pf can 'see' the dhcp traffic on the production nets as per the manual. As I said, dhcpd is configured correctly as if I put a port into the reg vlan manually via the switch CLI it picks up an IP - it's just when Packetfence puts the port into reg vlan, no dhcp request is ever receieved on the pf box and so the client doesn't get an IP.

Subject: Re: [Packetfence-users] Fwd: VLAN assignment and DHCP Who's leasing the IP's for your Production (Normal) VLAN? This should be a DHCP server in your production VLAN that gives you the correct IP and DNS information once you've registered with PF. Make sure the scopes don't overlap with the PF DHCP ranges. -----Original Message----- From: Mark Holmes [mailto:mar...@nu...] Sent: Monday, February 21, 2011 6:28 AM To: pac...@li... Subject: Re: [Packetfence-users] Fwd: VLAN assignment and DHCP I do, yes. I'm using pf as the dhcp for the reg and iso VLANS. I know dhcpd is working correctly, as if I manually put a port into the registration VLAN using the switch CLI it picks up an IP in the registration range.
