DHCP Lease Timeout?

I am encountering an error and am racking my brain here. Please see below. Thank you all so much!

@Kureebow Offen this is caused by old school spanning tree being enabled without port-fast. Check the switch configuration to see if you can change the setting to rapid spanning tree or use port-fast.

@Sebastian-Roth my network supervisor is looking into the Spanning tree settings. However, he did ask if FOG has the capability to boot with a usb drive for the time being. We are rushed to get some devices imaged today.

Try inserting one of those cheap 5 port (i.e. dollar store) 1GbE switches between the building switch and the pxe booting computer. If that solves the problem then its a spanning tree issue.

If that’s the case your network engineer will need to set the port where you expect to see a pxe booting computer, to either portfast/fast-stp/rstp/mstp or whatever your switch mfg calls it. If you are entertaining using usb boot, it might be just as easy to walk around with that cheap-o GBE network switch.
