I'm trying to PXE-boot desktop-machines to install a new OS over the network, but it isn't picking up an IP address via DHCP during boot. When an OS is already booted on the machine, it is working fine.
In the past i had some issues with this, because of misconfigured RSTP. But with
spanning-tree [PORT] admin-edge-port on HP-Switches (equivalent to ciscos
portfast i guess) i thought i solved this. Now it is back, with exactly the same symptoms...
Client -> Server: DHCP-Discover Server -> Client: DHCP-Offer Client -> Server: DHCP-Discover Server -> Client: DHCP-Offer .... looping...
I tried several things:
- extending the boot time (memory check on the client)
- disabling RSTP
- disable auto-negotiate between Switch and Client
I am at my wit's end. Someone has an idea?
