[SOLVED] PXE-E51 "No DHCP or DHCP Proxy Offers received"

[88fingerslukee]

Hi Everybody,

I’m posting this as a problem and a solution. I hope it helps somebody:

I now have FOG working really well with most of my clients; however, I have one client that simply refuses to get an IP address from the DHCP server. It exits out with a PXE-E51 “No DHCP or DHCP Proxy Offers received” error.

I found this weird because the rest of the clients get an IP from the DHCP server no problem. The solution I found was something I knew nothing about before I researched it.

If you have manageable switch and you have Spanning-Tree enabled on it. You’ll need to enable Port-Fast (Cisco lingo) or Fast-Link (Netgear lingo) on each port that’s giving you trouble. It may be called something else on your switch, so it’s worth looking at your manual.

YMMV with this. I have no idea if it breaks anything else in the network but I haven’t noticed anything yet.

It won’t “break” anything else on the network, but it does leave you open to creating a loop and bringing the network down. Generally, you turn on port-fast, or set the ports to “edge” if you know they will also connect to an end point and not another switch.

Thanks for the info. That’s useful.
