Clients using PXE don't get an IP address

[vancampdax]

I'm trying to install an Altiris deplyment server but my clients even don't get an IP address during the PXE boot.

I configured the port with "switchport host" and have on my router the command "ip helper" active.

As soona s the clients boot their OS, they receive an IP address.

Why aren't clients getting an IP address ( via DHCP ) when they boot in PXE but do get an IP address ( via DHCP ) when they boot their OS.

Is this a IOS bug ???

Have you checked that spanning-tree portfast is configured on the client-ports?

If not, the PXE-boot will time-out before the port forwards the request. The DHCP comes later and by then, the port is forwarding traffic.

Hope this explains your issue.

The command "switchport host" disables the spanning-tree on the port.

I just found the problem.

The Altiris deployment Ip address was faulty !

It seems that the DHCP request and the boot file are connected together.

If your PXE server isn't configured correct you wont get an DHCP address either
