When they bring up a new machine and do dhcp, it takes about 45 seconds to get the new IP. I'm convinced most of the time is the switches playing games trying to figure out the most efficient way to connect the newly introduced machine to the dhcp server. Isn't that any easy problem to solve? Whichever switch the new machine is connected to just looks in its tables and asks "how did I send

But I'm no expert, so perhaps I'll learn something!
Actually, with Spanning Tree Protocol (STP), it shouldn't even take that long. Each switch maintains a table of devices (MAC addresses) connected to it and through STP, the switches determine the best path. If a link fails, an alternate path, if available, is used. This all happens automagically. Of course, switches know nothing about DHCP requests or anything else to do with IP. They handle level 2 traffic (Ethernet etc.) only, not higher protocols. https://en.wikipedia.org/wiki/Spanning_tree_protocol -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
