DHCP Timeout (Preboot Execution; PXE) Nortel Baystack 450 2T - PBX Info :: Your Free PBX, PABX and Telephone Information Resource

06-30-2005, 10:24 AM

A few weeks ago I made an Update on our Nortel Baystack 450-24T Switches. Before they had the Software Release 3.0, now they have 4.5.2.4! After I updatet the switches we can't Image our PC's anymore. We work with Novell and our PXE get's an DHCP Timeout after booting the Linux Kernel. I found some information on the Microsoft Homepage, this happends because of the loop detection (Spanning Tree). But before we made the update it worked with the same Attitudes. I hope someone can help me with this problem.

Thanks

Version 4 introduces the new rapid-spanning tree protocol standard. try enabling fast-start on all the ports accept for uplinks and if this does not work you may have to change the spanning-tree protocol type in the global STG settings.
